Korea’s Borders Through Time: Three Kingdoms to the Korean War

Korea’s borders have changed dramatically over time, from the era of the Three Kingdoms to the divided peninsula seen today. Goguryeo, Baekje, and Silla competed for power before Silla united most of Korea, while Balhae rose in the north across northern Korea and Manchuria. Later, Goryeo reunited the peninsula, the Mongols made it a vassal, and Joseon expanded north to roughly the modern border.

The story then moves into the modern era, when Korea fell under Japanese influence and was annexed in 1910. After World War II, the peninsula was split into a communist North and a US-backed South, leading to the Korean War. North Korean forces nearly took the South, but US-led troops pushed them back, China intervened, and the front eventually stabilized near the original border.
