The Korean War began on June 25, 1950 and ended on July 27, 1953.
The Korean War took place on the Korean Peninsula, initially in South Korea, and then later in North Korea as well.
North Korean communist forces called the North Korean People's Army (KPA) under President Kim Il-Sung began the war. Mao Zedong's Chinese People's Volunteer Army (PVA) and the Soviet Red Army joined later. Note - the majority of the soldiers in the People's Volunteer Army were not really volunteers.
On the other side, the South Korean Republic of Korea Army (ROK) joined forces with the United Nations. The UN force included troops from:
- United States (approx. 327,000)
- Great Britain (14,000)
- Canada (8,000)
- Turkey (5,500)
- Australia (2,300)
- Ethiopia (1,600)
- The Philippines (1,500)
- New Zealand (1,400)
- Thailand (1,300)

Who Won the Korean War?
Neither side actually won the Korean War. In fact, the war goes on to this day, since the combatants never signed a peace treaty. South Korea did not even sign the Armistice agreement of July 27, 1953, and North Korea repudiated the armistice in 2013.
In terms of territory, the two Koreas returned essentially to their pre-war boundaries, with a demilitarized zone (DMZ) dividing them roughly along the 38th parallel. The civilians on each side truly lost the war, which resulted in millions of civilian deaths and economic devastation.
Total Estimated Casualties
- South Korea and UN troops: 178,236 killed, 32,844 missing, 566,314 wounded.
- North Korea, USSR, and Chinese troops: Numbers are unclear, but American estimates range from 367,000 to 750,000 killed, about 152,000 missing or taken prisoner and 686,500 to 789,000 wounded.
- South Korean civilians: 373,599 killed, 229,625 wounded, and 387,744 missing
- North Korean civilians: estimated 1,550,000 casualties
- Total civilian deaths and injuries: approximately 2.5 million
