While it is true that the theoretical and ideological origin of the socialist and communist tendencies is common, there is a significant difference between socialism and communism from the economic, political and sociological point of view. Communism is commonly understood to be the last phase of socialist theory. Over the years and the appearance of new socio-political and economic models, both ideological tendencies have diverged. Mostly thanks to new mixed perspectives and coexistence with the capitalist and free market model.

Feudalism was the socioeconomic system that prevailed in the Middle Ages, but even survived in some regions of Europe in the Modern Age. The feudalism was a set of practical issues involving economic, social and political. Between the 5th and 10th centuries, Western Europe underwent a series of transformations that enabled the emergence of these new ways of thinking, acting and relating.
