The contemporary culture of South Korea developed from the traditional culture of Korea which was prevalent in the early Korean nomadic tribes. By maintaining thousands of years of ancient Korean culture, with influence from ancient Chinese culture, South Korea split on its own path of cultural development away from North Korean culture since the division of Korea in 1945. The industrialization, urbanization and westernization of South Korea, especially Seoul, have brought many changes to the way Korean people live. Changing economics and lifestyles have led to urbanization—a concentration of population in major cities, with multi-generational households separating into nuclear family living arrangements. Today, many cultural elements from South Korea, especially popular culture, have spread across the globe and have become some of the most prominent cultural forces in the world.

The history of South Korea begins with the Japanese surrender on 2 September 1945. At that time, South Korea and North Korea were divided, despite being the same people and on the same peninsula. In 1950, the Korean War broke out. North Korea overran South Korea until US-led UN forces intervened. At the end of the war in 1953, the border between South and North remained largely similar. Tensions between the two sides continued. South Korea alternated between dictatorship and liberal democracy. It underwent substantial economic development.
