The Korean War (1950-1953) involved four phases: South's liberation, UN invasion northward, Chinese counterattack, and a stalemate leading to peace talks.

Phase 1: Liberating the South

Phase 1: Liberating the South

North Korean forces attacked South Korea on 25 June 1950.
The United Nations, led by the USA, supported South Korea.
- UN troops helped South Korea push North Korean forces back.
The South's liberation marked the first phase, ending by September 1950.

Phase 2: UN invasion

Phase 2: UN invasion

General MacArthur led the UN forces into North Korea in October 1950.
- UN troops advanced towards the Yalu River, the Chinese border.
The UN aimed to reunite Korea under South Korean control.
This phase showed UN success before Chinese intervention.

Phase 3: Chinese counterattack

Phase 3: Chinese counterattack

China entered the war in late October 1950, sending hundreds of thousands of troops.
Chinese forces pushed the UN back into South Korea.
- This counterattack reversed UN gains and caused heavy casualties.
Fighting shifted southwards, showing the war's changing tide.

From mid-1951, the front stabilized near the 38th parallel.
- Neither side gained significant ground.
The UN and North Korea began peace talks in July 1951.
