In the later half of the 19th century capitalist nations began producing more goods then they could sell in their domestic markets. So they started seeking out foreign markets. This led to Imperialism . Foreign countries were required to agree to allow foreign goods to be sold in their country or face the wrath of a superior military. Socialism is an economic system in which the means of production are owned and controlled by the people.
Socialism is economic democracy.
Historically many socialists have advocated state control, but not all socialists. Those that do are called state socialists. There are basically two definitions of communism. The first refers to a society similar to the Soviet Union or China. It has a totalitarian one-party state running the economy and controlling citizen's lives.
