The most powerful of which was the first industrial power in the world - Great Britain. Europeans mastered almost the whole world, turned the rest of the countries into colonies, sales markets their goods.

By the beginning of the 20th century, the number of industrialized countries had increased. At the same time, non-European countries began to play an increasing role in world affairs - the United States and Japan, which had embarked on the path of industrial development.

Overall, out of a total world population of 1,680 million people in industrial, industrial-agrarian and agrarian-industrial countries at the beginning of the 20th century were home to about 700 million people. About 600 million lived in the colonies (including approximately 400 million in the British).

A special place was occupied by a group of states with a total population of about 380 million people, which were formally independent, but in fact were in the position of semi-colonies of the great powers. At the beginning of the century, these included China, Persia (Iran), Turkey, Siam, Egypt, Korea, and a number of others. The signs of a semi-colony were, as a rule, the acceptance by its authorities of unequal terms of trade, the provision of special privileges to foreign citizens, including their lack of jurisdiction local authorities in case of crimes. Semi-colonies became countries that, due to military-technical backwardness and the weakness of the central government, were unable to resist colonial empires, but at the same time avoided complete conquest. This was due to the competition of industrial powers that interfered with each other, a special geopolitical position semi-colonies, which made it difficult to conquer them.

§ 1. Industrialized countries: Aggravation of contradictions

By the beginning of the 20th century, the most important characteristic of world development was not only an increase in the number of industrial countries, but also their division into two groups, the first and second waves of modernization, or organic and catching up industrial development.

Countries of the first echelon of industrial development.

For this group of countries, which included Great Britain, France, the United States, as well as a number of medium and small European countries (Belgium, Holland, Scandinavian states), the gradual mastery of the industrial type of production was characteristic. The industrial revolution, then the transition to mass, large-scale conveyor production took place in stages, as the corresponding socio-economic and cultural prerequisites matured. These included the following.

First, the maturity of commodity-money relations, the large capacity of the domestic market, its readiness to absorb large volumes of industrial output.

Secondly, the high level of development of manufactory production, which was primarily subjected to modernization.

Thirdly, the presence of a numerous layer of the poor, people who have no other sources of livelihood, except for the sale of their labor force, as well as a layer of entrepreneurs who have accumulated capital and are ready to invest it in production.

So, in England, the industrial revolution began at the end of the 18th century. Heavy industry, mechanical engineering, as an independent industry, began to develop in the 1920s. XIX century. Following England, the industrial revolution began in the northern states of the United States, which were not burdened with remnants of feudal relations due to the influx of emigrants from Europe with free labor resources. However, the full industrialization unfolded in the United States after civil war 1861-1865 between North and South, which ended the plantation system of agriculture in the southern states, based on slavery, and strengthened the unity of the country's domestic market. France, where manufactory production traditionally existed, bloodless Napoleonic wars, entered the path industrial development after the revolution of 1830

Second echelon countries of modernization.

Germany, Russia, Italy, Japan, Austria-Hungary were delayed in joining industrial society for different reasons. For Germany and Italy, with the oldest manufacturing traditions in Europe, centers of industry already established in the 19th century, the main problem was fragmentation into small kingdoms and principalities, which made it difficult to form a sufficiently capacious internal market. Only after the unification of Italy (1861) and Germany under the leadership of Prussia (1871) did the pace of their industrial development accelerate. In Russia, Japan, and Austria-Hungary, industrialization was hindered by the preservation of pre-capitalist relations in the countryside, various forms of personal dependence of the peasantry on landowners, limited domestic financial resources, and the prevalence of the tradition of investing capital in trade rather than in industry.

The impetus for transformations in Germany and Italy came from the ruling circles, striving to further strengthen the positions of their states in the international arena, dreaming of creating vast colonial empires.

In Russia, one of the reasons for the transition to reforms was the defeat in the Crimean War of 1853-1856. which showed its military-technical lag behind Great Britain and France.

In Japan, modernization was preceded by the threat of bombardment of its ports by Admiral Perry's squadron of American ships in 1854, which revealed its defenselessness. The forced acceptance of unequal terms of trade and relations with foreign powers meant the transformation of Japan into a dependent country. This caused discontent among many feudal clans, samurai (chivalry), merchant capital, and artisans. As a result of the outbreak of the revolution, Japan became a parliamentary, centralized monarchy headed by the emperor, embarked on the path of reform and industrialization.

With a large variety of countries in the second echelon of industrial development, a number of common, similar features were revealed, the main of which was the special role of the state during the period of modernization. So, in 1913 in the USA the state disposed of only 9% of the gross national product (GNP), while in Germany - 18%. The special role of the state was explained as follows.

First, it was the state that was the main instrument for implementing reforms designed to create the preconditions for modernization. The reforms were supposed to expand the scope of commodity-money relations, reduce the number of low-productive subsistence and semi-subsistence farms in the countryside, and thereby ensure the release of free labor for use in a growing industry.

Secondly, in conditions when the need for industrial goods in the domestic market was previously satisfied by importing them from more developed countries, the modernizing states were forced to resort to protectionism, the introduction of increased customs duties on imported products to protect only the growing strength of domestic producers.

Thirdly, with limited internal resources for modernization, weakness of domestic capital, the state directly financed and organized the construction of railways, the creation of factories and factories. In Russia, and especially in Germany, the greatest support was given to the military industry and its service industries. Typical was the creation of mixed companies and banks with the participation of state and sometimes foreign capital. The role of foreign sources of modernization financing in various forms(direct investment, participation in mixed companies, the purchase of government securities, the provision of loans) was especially large in Austria-Hungary, Russia, Japan, less - in Germany and Italy.

Most of the countries that carried out accelerated modernization had no alternative to it, since they were in danger of becoming second-rate, dependent states. Thus, Japan only in 1911 got rid of all the previously unequal treaties imposed on it. At the same time, the accelerated development of the countries of the second echelon of industrialization was a source of exacerbation of many contradictions both in the international arena and within the modernizing states themselves.

Exacerbation of the contradictions of world development.

One of the reasons for the growth of contradictions was the increase in the number of industrial countries, since the industrial capital of each of them sought to win a place for itself in the national and world markets. Even when England was the main "industrial workshop of the world", in 1825, 1836, 1847, she faced crises of overproduction. All the markets open to her could not absorb the products produced by her. In 1857, the first global industrial crisis broke out, affecting not only Great Britain, but also other countries that had embarked on the path of industrial development. Between the industrial capital of these countries, the struggle for foreign markets intensified, on the possession of which the well-being of the becoming industrialized countries depended.

The capacity of world markets gradually increased. Firstly, this was due to an increase in the standard of living in industrialized countries (the domestic market of the United States was considered especially capacious and dynamic at the beginning of the century). Secondly, with the erosion of the subsistence and semi-subsistence economy of the colonies and dependent countries, the development of commodity-money relations in their territories, which accelerated the formation of the global market and expanded consumer demand. At the same time, the development of world markets constantly lagged behind the growing possibilities of production, which led to a deepening economic crises. The crisis marked the onset of a new, 20th century. Slipping to the crisis was outlined on the eve of the First World War of 1914-1918.

Crises accelerated the concentration and centralization of capital, contributed to the ruin of weak and inefficient enterprises and, from this point of view, contributed to an increase in the competitiveness of the economy. At the same time, causing an increase in unemployment, exacerbation social relations, they created serious problems for industrial countries.

The social consequences of the crises were most painful in the countries of the second echelon of modernization. In the countries that later embarked on the path of capitalist industrial development, social conflicts between labor and capital were combined with the unresolved agrarian question, the continuing struggle of the peasantry for the completion or more just implementation of the agrarian reform. In the countries of the first echelon of modernization, however, the agrarian issue was resolved in one way or another.

In countries where the contradictions between entrepreneurs and employees made themselves felt in the last century, gradually aggravated, experience has been gained in pursuing a flexible social policy. The struggle of the working people for better working conditions and higher wages was carried out within the framework defined by law, on the basis of bargaining and compromises between trade unions and employers. At the same time, maintaining stability in society largely depended on the resources that could be allocated to reduce the severity of social problems. Where employees guaranteed pension provision, an accident insurance system was introduced, acceptable conditions were created for access to medical care, education, etc., workers did not have an incentive to express social protest.

In the countries of the second echelon of modernization, the state not only did not have the experience and means to solve social problems, but also, incurring large expenses to support domestic production, was forced to take unpopular measures, raising taxes, seeking other measures to replenish the treasury at the expense of the population.

It is indicative that it was Russia, which had far fewer resources for social maneuvering than other industrial countries, that experienced the greatest upheavals in the 20th century. Thus, the production of national income per capita in 1913 in Russia (in comparable prices in 1980) was only $350, while in Japan it was $700, in Germany, France and Great Britain it was $1,700 each. , in the USA - 2325 dollars.

The most important source of solving internal problems for the countries of the first wave of modernization, especially England and France, were colonial empires. Great Britain managed to create the most extensive colonial empire in the world. More than a quarter of the world's population lived in its possessions, their territory exceeded the area of ​​​​the metropolis by almost 100 times. The second colonial power in the world was France, which put under its control North and Equatorial Africa, Indochina.

The wealth exported from the colonies, the ability to monopolize their markets, receiving super profits, enriched both the ruling elite and the general population of the metropolises. The poor, the unemployed, unable to find work in the metropolises, emigrated to the colonies. This was facilitated by the emerging diamond and gold rushes, the distribution of land on favorable terms. The constant outflow of surplus labor reduced the level of social tension. The colonies were a stable, guaranteed market for products, which partly mitigated the severity of crises for the metropolises.

The flip side of prosperity was the constant flight of capital. A high standard of living led to a rise in the cost of labor, which made it unprofitable to invest in the economy of the metropolis proper. There were no incentives for its development, since the markets of the colonies were not too demanding on the assortment and quality of products. British bankers preferred to invest in colonies, dominions (colonies populated mainly by immigrants from the metropolis and given self-government opportunities, Canada - in 1867, Australia - in 1901, New Zealand- in 1907), as well as to the US economy. French capital was invested in government loans of those countries where high profits could be made quickly, in particular Russia.

Thus, in the economy of the most developed countries of the world, tendencies to stagnation have been outlined, it has lost its dynamism, and its growth rates have slowed down. On the contrary, in states that did not create vast colonial empires, such as Germany, the USA, Japan, most of the capital was directed to the development of national economies. Later, when they entered the path of industrial development, they equipped the emerging industry with the most advanced technology, and this provided them with advantages in the fight against competitors. This led to the emergence of a discrepancy, a contradiction between the levels of development of industrial countries and the distribution of colonies and spheres of influence between them.

An attempt to resolve this contradiction at the beginning of the 20th century, in conditions when the primary division of the world had already been completed, took the form of a struggle for the redistribution of colonies and markets for goods. The first war of the new era for the redivision of the world was the Spanish-American (1898), as a result of which the United States seized the Philippines, the islands of Puerto Rico and Guam from Spain, and granted independence to Cuba. The second is the Anglo-Boer (1899-1902), as a result of which England established complete control over South Africa, capturing the Transvaal and Orange republics, founded by immigrants from Holland.

Germany, Japan and Italy were the most active and aggressive in colonial policy at the beginning of the century. As competition intensified on world markets, colonial policy intensified, and the rivalry of the leading powers on the world stage intensified.

Contradictions between the mother countries and the peoples of the colonial and dependent countries began to become increasingly acute. With the development of commodity-money relations in these countries, the emergence of a stratum of the national bourgeoisie, the intelligentsia, who received a European education, protest movements against colonial status intensified. Anti-colonial movements were often supported from outside by countries striving to repartition the world and expand their own spheres of influence. Thus, on the eve of the war with Spain, the United States showed solidarity with the liberation movement in the Philippines and Cuba, which, however, did not prevent them from including these countries in the orbit of their own influence after the victory. In Japan, the slogan "Asia for Asians" was popular, implying that Asian countries should free themselves from the domination of white colonialists and enter the Japanese sphere of influence.

Tsna - a river in the Tambov and Ryazan regions of Russia, the left tributary of the Moksha (Volga basin).

The total length of the Tsna is 445 km, of which 325 km are within the Tambov region and 120 km within the Ryazan region. Tsna begins in the Sampursky district of the Tambov region from the confluence of two small water streams: Wet Top and Bely Plyos. The basin area is 21.5 thousand km2.

Tsna is a calm flat river. The river bed is winding, the width is from 40 to 200 m. The depth of the river is 2-5 m, and in the whirlpools - up to 10 m. There are 5 dams in the section of the river between Tambov and Morshansk.

It receives numerous tributaries from the right and left: Karian - 48 km long, Lipovitsa - 52 km, Lesnoy Tambov - 89 km, Chelnovaya - 121 km, Kersha with Khmelina - 86 and 49 km, Kashma with Big and Small Lomovis - respectively 111, 106, 66 km, Serp - 66 km, etc.

Below the village of Semikino are lakes Lebyazhye and Orekhov Zaton - the largest floodplain lakes on the Tsne River.

The left bank of the river is treeless and heavily populated. A strip of forest stretches almost everywhere along the right bank, but it comes out to the water only in some places, since during the Great Patriotic War was cut down.

The cities of Kotovsk, Tambov, Morshansk, Sasovo stand on the river.

Shipping

The Tsna River is navigable only in places, from Tambov to the mouth. To the list of waterways Russian Federation only a 47 km long section from the village of Tensyupino to the place where the Tsna flows into the Moksha was included.

Bridges and crossings

There are many bridges across the Tsna River, in particular the bridge in Morshansk, Tambov Region; bridge in the village Yambirno, Ryazan region; railway bridge near the village of Periksa, Tambov region; railway bridge in the city of Sasov, Ryazan region; cable-stayed and Tezikov (Pervomaisky) pedestrian bridges in Tambov, etc.

Fish

The Tsna River will please anglers with an abundance of different fish. Caught verkhovka, chub, silver bream, ruff, asp, golden carp, carp, silver carp, bream, rudd, tench, river lamprey, European perch, burbot, roach, gudgeon, pike perch, catfish, pike , bleak and ide. In some seasons, when the water is quite clear, spearfishing is relevant.

The Tsna River, a large left tributary of the Moksha, forms southwest of the village of Verkhotsenye and flows into the Moksha at the 44th km in the Ryazan region. The length of the river is 451 km, the length of the described section is 321 km. The banks of the Tsna are mostly meadow, the channel is winding, the speed is insignificant: from 0.4 km / h in the reaches to 1.5 km / h in the riffles, there are a lot of algae, thickets of reeds. The right bank is sparsely populated, the forest behind the meadows, sometimes comes close to the water. Fields and villages stretch almost entirely along the left bank. Six waterworks facilities have been built on the Tsna, and the river is therefore navigable.

From the village of Sampur to the village of Kuzmina Gat 53 km, then to the city of Tambov 33 km, then to the city of Morshansk 135 km, then to the village of Nosiny 53 km.

We start the route in the flood from the village of Sampur, where a bus runs from Tambov (54 km). The river here is narrow, shallow and flows first to the northwest past the village of Tekino on the left bank and the village of Nikolskoe. Below the village of Znamenka (on the left bank), the regional center of the Tambov region, where the river is crossed by a road bridge, the Tsna receives the left tributary of the Karian and turns north. Below the left tributary of the Lipovitsa, the river becomes more full-flowing, turns to the northeast and below the bridge of the Tambov-Balashov railway line, it receives the right tributary of the Lesnaya Tambov. Now the river flows north to Tambov. We pass the village of Kuzmina Gat and the city of Kotovsk on the right bank. The railroad and highway run along the left bank. Tambov (1636) is a large industrial and cultural center. The city has a museum of local lore, an art gallery, the Gostiny Dvor building of the 18th century.

It is difficult to find a place in our country more suitable for a harmonious peasant life than the Tsna valley. Fat black soil, favorable climate, fish river, water meadows and vast riverine forests - all this is the Tsna valley. Its left bank is heavily populated, which, together with the fact that the river is regulated for navigation, reduces the advantages of Tsna in relation to tourist travel. Large left-bank villages following one after another stand on the busy Tambov-Morshansk-Shatsk highway.

In Tambov, the dam is to be demolished.

Below Tambov Tsna is a calm river 40-80 m wide (on rifts it decreases to 25-30 m), flowing in a wide valley with backwaters, oxbow lakes and channels. On the left bank, chains of villages stretch 1-2 km from the water, on the right, at the same distance, there is a forest. Near the village of Dubrova and the village of Donskoye, the river becomes shallow, forming rifts. 40 km below Tambov, the Gorelsky sluice and the hydroelectric power station (there is a bus from Tambov, 27 km). Behind the village of Dubki at the gateway we pass the village of Chernyavoe on the left bank and the village of Quiet Corner near the pine forests. Tsna forms below Malinovsky turns and rifts. The right bank is elevated, on the left - the hill "fortified". Near the village of Troitskaya Dubrava, on the left bank, the river makes a steep bend, cut by a non-navigable channel, at the next bend - a hydroelectric complex, run-out on the left. Behind the village of Kuleshevo a good place to relax in the oak forest. Near the village of Perkino (on the left bank), where the forest approaches the shore, there is a low bridge with a diversion span. There are similar bridges in other places.

Below the mouth of the right tributary of the Golyma, behind the timber industry enterprise, the Semikinsky Canal, which significantly shortens the path along the Tsna, leads to the large Linevo Bay. In the floodplain of Tsna near Perkino, Semikino and below, there are labyrinths of oxbow lakes overgrown with reeds, bays, lakes. Between Lake Lebyazhye and Orekhov Zaton is Kulevatovskaya Luka, on the left bank of which stands the village of Kulevatovo with an old park. There is a bus from Tambov (69 km) or Morshansk (30 km). The Tsna receives here a significant left tributary of the Chelnovaya.

We sail below the village of Peski and the large village of Otyassy. Here Tsna makes two major turns, forming a large bay connected by a narrow channel with a chain of oxbow lakes. Behind the village of Mamonovo - a dam and a lock, run-out on the right. Here is a good place to relax, there is a forest. Below the confluence of the right tributary of the Kersha, after the village of Kershinsky Borki, floods begin. From the village of Cherkino, the Tsna flows for 10 km to the village of Iven on the left bank of the Iven turns. Beacons serve as a guide.

From Tambov to Morshansk, the river is accompanied by a forest at some distance, now approaching, now receding; the city of Morshansk is a district center in the north of the Tambov region, it stands on the railway line Ryazhsk-Penza. The city has a museum of local lore, historical-revolutionary and architectural monuments. From Morshansk there is very little forest around. Below Morshansk, a large right tributary of the Kashma flows into the Tsna, beyond which, near the village of Staroe Ustye, the river is crossed by the Ryazhsk-Penza railway line. The river flows north. Tsna becomes wider, beaches appear. The forest moves to the right, only occasionally approaching the banks. The current is noticeable, willow bushes serve as a guide to the big water. The river flows through floodplain meadows, and only in front of the village of Mutasovo (on the left bank) a wood stretches on the left 200 m from the water. 3 km below, on the right bank, a small forest grows, to which a backwater approaches.

Below the village of Alkuzhi (on the left bank), Tsna receives the Serp River from the left; Serpovoe village - near its mouth. There is a dam and a lock. An old channel approaches the canal in front of the lock, you can cross it by dragging. 10 km below the dam, Tsna approaches the right ridge, washing it away. The high sandy shore is covered with pine trees. The river winds then among the meadows, again approaches the pine forest, not reaching the village of Rysli on the left bank. Soon a floating bridge. Near the village of Chernitovo (on the left bank) is the next dam. Carrying is difficult here, it is better to lock. Below the left bank is bare, the river expands to 100-200 m and beyond the village of Nosiny on the left bank passes into the Ryazan region.

The sources of the Tsna River (the left tributary of the Moksha) take south-west of the village of Verkhotsenye. It flows into Moksha in the Ryazan region, at the forty-fourth kilometer. The length of Tsna is 451 kilometers. Its channel is winding, the banks are mostly meadow, the speed of the current is small - from 0.4 to 1.5 kilometers per hour. There are many reed thickets and algae in the river. On the sparsely populated right bank, the forest in some places rises to the water. The left bank is almost entirely occupied by fields and settlements. There are 6 hydropower stations built on Tsna, thanks to which the river is navigable.

The length of the river from the village of Sampur to the village of Kuzmina Gat is 53 kilometers, then to Tambov 33 kilometers, then to Morshansk 135 kilometers and to the village of Nosiny - 53 kilometers.

From the village of Sampur, where the Tsna is shallow and narrow, it flows to the northwest, past the village of Tekino located on the left bank and the village of Nikolskoye. Behind the district center Znamenka, where a road bridge was built across the river, the left tributary of the Karian flows into the Tsna and then the river turns north. Below the Lipovitsa River, the left tributary, the Tsna, becoming more full-flowing, turns to the northeast and, behind the bridge of the Tambov-Balashov railway line, the right tributary of the Lesnoy Tambov flows into it. From here the river flows north to the city of Tambov. The city of Kotovsk and the village of Kuzmina Gat are located on its right bank. On the left bank are roads and railways.

Perhaps, in all of Russia there is no place where it is so free to live a rural life as in the valley of the Tsna River. Fertile lands, mild climate, a river rich in fish, green meadows and endless forests - all this is in the Tsna valley. The densely populated left bank, together with regulated navigation, somewhat reduces the attractiveness of the river for tourist travel. Large villages located on the left bank stand on the busy highway Tambov-Morshansk-Shatsk.

Below Tambov, the width of the Tsna is from 40 to 80 meters, on the rifts it narrows to 25-30 meters. The course of the river, which runs through a wide valley, is calm, with oxbows, backwaters and channels. On the left bank, at a distance of one or two kilometers from the water, there are settlements, along the right stretches the forest. Near the villages of Donskoye and Dubrava, Tsna forms rifts. Forty kilometers from Tambov, downstream, there is a hydroelectric power station and the Gorelsky sluice. Below the lock, behind the village of Dubki on the left bank, there are the villages of Chernyavoe and Quiet Corner, not far from the pine forest. On the left bank of the river there is a hill fort, the right one is elevated. Near the village of Troitskaya Dubrava, located on the left bank of the river, Tsna forms a bend, which is crossed by a non-navigable channel. At the next bend there is a waterworks. The oak grove, located outside the village of Kuleshovo, is a great place to relax. On the left bank of the river, not far from the village of Perkino, the banks are connected by a low bridge.

Below the confluence of its right tributary, the Golym, with the Tsna, there is the Semikinsky Canal, leading to the Linevo Bay, which significantly reduces the path along the river. Below the villages of Semikino and Perkino in the river valley there are many lakes, oxbow lakes and bays overgrown with reeds. On the bank of the Kulevatovskaya Luka backwater, located between the Orekhovy backwater and Lake Lebyazhye, there is the village of Kulevatovo with an old park. Here, a large left tributary, the Chelnovaya River, flows into the Tsna.

Below the village of Otyassy and the village of Sands, Tsna makes two sharp bends, forming a vast bay, which is connected by a narrow channel with a string of oxbow lakes. Behind the village of Mamonovo, where the gateway and the dam are located, there is a forest where you can have a wonderful rest. Below the mouth of the Kersha, the right tributary of the Tsna, there are overflows. From the village of Cherkino to the village of Iven for 10 kilometers - Ivensky turns, marked with beacons.

The banks of the Tsna from Tambov to Morshansk are overgrown with forest, now approaching, now moving away from the water. From Morshansk, the forests become much smaller. Below the city, Tsna receives a large right tributary of the Kashmu, behind which a line passes through the river. railway Ryazhsk-Penza. Further, Tsna becomes wider, the forests are quite far from the coast, only in some places approaching the water. The current here is much faster, floodplain meadows stretch along the banks, only in front of the village of Mutasovo on the left bank, two hundred meters from the water, there is a small forest. Downstream, after 3 kilometers, a small grove grows on the right bank of the river.

Below the village of Alkuzhi, located on the left bank, the left tributary Serp flows into the Tsna. Not far from the confluence is the village of Serpovoe, there is a dam and a lock. Ten kilometers from the dam there is a high sandy shore overgrown with pines, which is washed away by the river. Further, the river winds among the meadows, and not reaching the village of Rysli, located on the left bank, a pine forest rises to its banks. Near the village of Chernitovo, located on the left bank, there is another dam. Downstream, the Tsna expands to 100-200 meters and, behind the village of Nosiny located on the left bank, passes into the Ryazan region.
