Final answer:
The truce in 1953 divided the Korean Peninsula along the 38th parallel, resulting in Communist North Korea and Democratic South Korea, and established the DMZ.
Step-by-step explanation:
The truce signed between North and South Korea in 1953 called for a cease-fire and officially divided the Korean Peninsula along the 38th parallel, forming Communist North Korea and Democratic South Korea. The Korean Armistice Agreement led to the establishment of the Korean Demilitarized Zone (DMZ) around this parallel, which is patrolled by both sides, and is known as the most heavily guarded border in the world. Despite the armistice, no formal peace treaty was signed, and the two Koreas remain technically at war to this day, with a significant military presence maintained along their common border.
