The Korean War (1950-1953)

The Korean War was a conflict between the Democratic People’s Republic of Korea (North Korea) and the Republic of Korea (South Korea), rooted deeply in the tensions of the early Cold War. It began on June 25, 1950, when North Korean forces, backed by the Soviet Union, crossed the 38th parallel in a sudden invasion of the South.[1] In response, the United Nations, led primarily by the United States, intervened on behalf of South Korea, marking one of the first major military actions under the UN’s collective security framework.

The war’s human toll was staggering. Countless North Korean civilians, desperate to escape the conflict and repression, sought refuge in the South, but many were unable to make the journey. The invasion and subsequent fighting caused widespread family separation, creating a humanitarian crisis that displaced millions and left lasting emotional scars.The Hungnam evacuation is one such example, in which hordes of desperate civilians crowded the port, pleading for passage aboard departing ships as United Nations and South Korean forces withdrew in December 1950. While the evacuation saved tens of thousands of lives, it also marked the last time many families would see each other, as the division of the peninsula soon became a permanent reality.

Over the course of the war, millions of people were killed, the majority of them civilians. Cities were reduced to rubble, and the Korean Peninsula became a focal point of international rivalry as foreign powers poured resources, soldiers, and weapons into the conflict, China on the side of the North, and the United States and other UN members on the side of the South[2].

Hostilities formally ceased on July 27, 1953, with the signing of an armistice agreement. This established the Demilitarized Zone (DMZ) near the 38th parallel, a heavily fortified buffer that still divides the peninsula today[3]. However, no peace treaty was ever signed, meaning the two Koreas still are technically at war.

The Korean War’s legacy extends far beyond its three years of fighting. It reshaped the geopolitical landscape of East Asia, cemented the division of the Korean people, and set the stage for decades of military tension, political hostility, and unresolved humanitarian issues that persist into the present day.
