When did the south Korea and north Korea ended?

The Korean War officially ended in 1953 with the signing of an armistice agreement. After three years of conflict North and South Korea agreed to a ceasefire and established the Korean Demilitarized Zone (DMZ) a 2.5 mile wide strip of land separating the two countries. Since then there has been no formal end to the war and both countries remain in a state of armistice. Despite the technical state of war diplomatic relations between the two states have improved since the 1990s leading to a series of reconciliatory agreements.

• 1953: Armistice agreement signed establishing the Korean DMZ.
• 1990s: Improved diplomatic relations between North and South Korea.
• 2000-2018: Multiple reconciliatory agreements and summits.
