Ancient history

First World War

The first half of the 20th century is a time of great change worldwide. In the First World War the great capitalist bourgeoisies of the powerful countries clashed for economic and political control of the world , which caused an economic, political, social and cultural crisis in the capitalist system. On the other hand, the organized and politically aware working classes carried out revolutions to achieve political power and from there change the entire economic, social and political system.


The current world (the 1980s and 1990s and the beginning of the 21st century) has not changed much in essence because the struggles between the great capitalist power groups of the powerful countries still continue, the economic crisis continues on a world scale, a crisis of culture and education and social degradation. But it still remains in force, that spirit of change of reality in men (scientists, artists and workers) who seek to create a new economy, new society, new government and new education different from the one that has been established in capitalism.
