Korea has been divided for over 50 years, separated into the communist North and capitalist South. While the two Koreas share a common culture and language, they have been antagonistic governments. There is a desire for reunification expressed by monuments in South Korea, but reunification faces challenges. The division began after WWII when the peninsula was divided and two governments formed, and the division was cemented after the Korean War. The large economic differences between the prosperous South and poor North pose a challenge, as reunifying could overburden the South Korean economy.
