Korean DMZ history, without the missing years.
The fighting did not simply end in 1953. Follow the armistice line through seven decades of ambushes, infiltrations, intelligence missions, defections, veteran service, and recurring crisis.
A cease-fire zone—not a settled border.
The Korean Demilitarized Zone was created by the July 27, 1953 Armistice Agreement. It follows the Military Demarcation Line for roughly 155 miles across the peninsula, extending about two kilometers on each side. Because no peace treaty replaced the armistice, it remains both a buffer and the front line of an unfinished conflict.
