1950 – 1953 · North Korea vs South Korea vs United States vs China
North Korea's invasion triggered a three-year UN-backed war that killed 3-4 million Koreans and left the peninsula permanently divided.
Divided after WWII, Korea saw North (Soviet-backed) and South (US-backed) governments dispute peninsula control. North Korean forces invaded June 1950, sweeping south rapidly. UN forces, mostly American, landed at Inchon (Sept 1950), pushing north. Chinese intervention (Oct 1950) pushed UN forces south. For two years, armies seesaw'd across the peninsula. Armistice (July 1953) restored the 38th parallel division. Korea remained technically at war (armistice, not peace treaty). Roughly 1 million military deaths (mostly Korean) and 2-3 million civilian deaths (disease, bombing, starvation). North and South remained hostile, militarized states.
The Korean War established the UN as an international security arbiter (though weakened by Cold War divisions). It demonstrated US commitment to containing communism globally. The war accelerated US militarization during the Cold War and justified NATO expansion. It created a permanent US military presence in East Asia (50,000+ troops remain). Korea's permanent division made it a Cold War symbol alongside Berlin and Vietnam. The Korean War and armistice remains among history's most unresolved conflicts—technically still ongoing.
