Korean War: The First Proxy War That Divided a Nation (1950–1953)

Welcome to The Gridded War — short cinematic battles explained in minutes. If you enjoy war history and strategy, subscribe. New battles every week. In June 1950, North Korean tanks crossed the 38th parallel, igniting the first major "hot" war of the Cold War. The United Nations, led by the United States, intervened to stop the spread of communism. Three years later, millions were dead, Korea was permanently divided, and the Cold War had entered a dangerous new phase. This breakdown covers: the causes of the war, the North Korean invasion, the Pusan Perimeter, the Inchon landing, the Chinese intervention, the Chosin Reservoir, the stalemate, and the armistice that left Korea divided to this day.
