Socialism in One Country is a political theory proposed by Joseph Stalin in the 1920s, arguing that a socialist state could be built and maintained in a single country, particularly the Soviet Union, without the need for worldwide revolution. This idea diverged from the traditional Marxist belief that socialism required a global uprising of the working class. The concept emphasized the need for strengthening the Soviet economy and consolidating power domestically as a means to secure socialism amid global capitalist threats.
