What war initiated after North Korea's invasion of South Korea in 1950?

The Korean War was initiated following North Korea's invasion of South Korea in June 1950. This conflict stemmed from the broader context of the Cold War, where tensions between communist and democratic nations were escalating. North Korea, backed by the Soviet Union and China, aimed to unify Korea under communist rule, while South Korea, supported by the United States and other Western allies, sought to maintain its independence and democratic governance.

The war resulted in significant military engagement and international involvement, with the United States leading the United Nations forces. The fighting continued until the armistice was signed in 1953, which effectively restored the boundaries at the 38th parallel but did not result in a formal peace treaty, leaving North and South Korea technically still at war.

Understanding this conflict is crucial in examining the dynamics of the Cold War and the geopolitical landscape of the time. The other options listed pertain to different events and periods in history that do not relate to the Korean Peninsula's division and conflict initiated in 1950.
