The crossing of the 38th parallel by North Korean forces and the subsequent crossing of the Yalu River by Chinese forces were central events in the outbreak and prolongation of the Korean War. The 38th parallel had been established as the boundary between North and South Korea following World War II, but North Korea did not recognize it as a legitimate border and invaded South Korea in 1950. The Chinese entered the war to support North Korea and pushed the fighting back to the 38th parallel and beyond, eventually leading to a stalemate and armistice in 1953.
