The term "permanent revolution" refers to a theory developed by Leon Trotsky, one of the leaders of the Russian Revolution in 1917. According to this theory, socialist revolutions must continue to occur in different countries until capitalism is completely overthrown and replaced with communism on an international scale.
Trotsky believed that the working class would lead these permanent revolutions, as they were the most oppressed by the capitalist system. He also argued that each country's socialist revolution must be independent of others, but at the same time, supportive and cooperative with other socialist countries in order to achieve global communism.
In summary, "permanent revolution" refers to a continuous process of socialist uprisings until capitalism is completely eradicated on an international level.
