Communist insurgency refers to a movement where groups seek to overthrow a government using guerrilla warfare and other tactics, often inspired by Marxist ideology. These groups aim to establish a communist state, promoting collective ownership and the elimination of class distinctions. Such insurgencies have occurred in various countries, notably during the 20th century in places like Vietnam and Cuba. They often arise in response to perceived social injustices, economic inequality, or foreign intervention, leading to prolonged conflicts that can significantly impact the affected nations and their populations.
