The study is a critical evaluation of Wallerstein's theory on "historical capitalism": drawing general theoretical conclusions especially on changing social forms and demanding a stricter class based approach. In the countries of the former "Eastern Block", the world-systems analysis is more useful in sociology and in historical science than the trendy theoretical tools, which replace the backward looking soviet "historical materialism", like the "civilization" based approach, the "clash of civilisations" or even fully desisting theories. It is time for social scholars in East Europe to read the inspiring sources of Wallerstein, namely the works of Latin American and African authors of the dependence school.
