Why did Korea split into two countries?
The division of Korea into two separate nations, North Korea and South Korea, traces its origins back to the closing days of World War II.
Korea had been under Japanese rule since 1910, and its fate after Japan's defeat was uncertain. In 1945, as World War II neared its end, Allied leaders decided to temporarily divide Korea for administrative purposes along the 38th parallel.
This division was meant as a short-term military convenience, with the Soviet Union taking control of the north and the United States taking control of the south. The initial plan was to administer Korea jointly until it could govern itself, but the Cold War tensions between the Soviet Union and the United States made this cooperation increasingly difficult.
As the Cold War intensified, the division between the northern and southern parts of Korea deepened. In the North, the Soviet Union supported the establishment of a communist government under Kim Il-Sung. In contrast, the South saw the establishment of a government led by Syngman Rhee with the backing of the United States, which was vehemently anti-communist.
These opposing regimes reflected the ideological battle lines of their respective superpower patrons, setting the stage for conflict. Each government in Korea claimed legitimacy over the entire peninsula, refusing to recognize the other as a legitimate government.
The simmering tensions escalated into outright war when, on June 25, 1950, North Korean forces, supported by Soviet tanks and heavy artillery, invaded South Korea. This marked the beginning of the Korean War, which saw massive involvement from both the United States and China, with the Soviet Union providing support to the North in the background.
The conflict was brutal and devastating, causing immense suffering and loss of life on both sides. After three years of fighting, the war ended in 1953 with an armistice agreement, but no formal peace treaty was ever signed. The armistice created the Korean Demilitarized Zone (DMZ), a heavily fortified border that remains to this day.
Following the armistice, both Koreas embarked on divergent paths of development influenced heavily by their ideological alignments. North Korea, under Kim Il-Sung, established a centralized, totalitarian regime with a state-controlled economy, pursuing policies of juche (self-reliance).
South Korea, meanwhile, initially struggled with political instability and economic challenges but eventually transitioned into a vibrant, democratic society with a dynamic market economy, particularly from the 1960s onward under the leadership of Park Chung-hee.
