Answer:
 North Korea as a communist nation and South Korea as a democratic nation.
Explanation:
 The Korean War was fought between the two sides of the Korean Penninsula within the context of the Cold War.
 North Korea counted with the support of China and the Soviet Union, while South Korea was supported by the United Nations, especially the United States.
 The war began when the North invaded the South and ended with an armistice creating a demilitarized zone between the two Koreas. Although this, no peace treaty was ever signed between the two of them, so technically they still at war.
