Outline of major events

Overview

The Korean War began with North Korean forces launching a surprise invasion, crossing over the 38th parallel at dawn on June 25th, 1950. The war lasted for three years and one month and as Korea and UN Forces together stopped the spread of communism, it is regarded as a war to protect world peace and a victory for free democracy.

Background and Cause

Influenced by the escalating tension between the U.S. and the Soviet Union after World War II, South and North Korea were divided along the 38th parallel soon after liberation in 1945 and were in conflict against each other. Even after the Korean government was established in 1948, there was sharp conflict among rightists and leftists leaving South Korean society extremely unstable. The Korean War broke out against this backdrop of instability, as well as Stalin’s strategy to communize the world and Kim Il-sung’s ambition for unification through military force, sparked by Mao Zedong’s promise of support.
