How did the Eastern European countries develop in the 50s and 80s? What was the special path of Yugoslavia? What are the reasons for the growing crisis phenomena in the socialist countries of Europe?

1. In the 50-80s. Eastern European countries were dependent on the USSR, the political position of these countries was determined by the actions and instructions of the Soviet Union. By the beginning of the 60s, the collectivization of agriculture had ended in a number of Eastern European countries. The nationalization of enterprises was carried out on a large scale.
2. The “special path” of Yugoslavia created its own problems. After all, all the Balkan peoples were under the auspices of this state. Disagreements arose between the peoples of Yugoslavia. In addition, Yugoslavia maintained an orientation towards a market economy, which ran counter to the views of the USSR. Not without the initiative of this country, the “Non-Aligned” movement was also created.
3. After perestroika, the USSR called on the Eastern European countries to democratize. However, many countries followed the path of reforms of the Soviet Union, which only worsened the economic situation of these countries. The intensification of opposition forces and the outflow of citizens to Western countries also influenced the economic decline.
