Why is Korea divided?

The Soviet Union occupied the northern half of Korea after World War II ended in 1945.

Southern Korea was controlled by the United States.

The peninsula was formally split in two on 9 September 1948.

The political differences between the two rival states led to the outbreak of a horrific war in 1950.

Three years later, a cease-fire agreement ended the Korean War.

But the North Korea and South Korea have to this day never signed a peace treaty.
