The 38th parallel is a circle of latitude that is 38 degrees north of the Earth's equatorial plane. It is significant as it roughly demarcates the border between North Korea and South Korea. This line became prominent after World War II when Korea was divided into two zones of occupation, leading to the establishment of separate governments. During the Korean War (1950-1953), the 38th parallel was the initial front line between the two Koreas. Although the war ended with an armistice, the line remains a critical point of tension and military presence, symbolizing the ongoing division of the Korean Peninsula.
