Japan invaded again and colonized Korea from 1910 to 1945. Then, Japan controlled Korea, including Busan. After World War 2 ended, Korea was divided into North Korea which was controlled by Russia and South Korean which was governed by the United State of America. During the Korean War, Busan was the temporary capital of South Korea from 1950 to 1953 and one of cities that were not conquered by North Korea when Korean War occurred. Therefore, many South Korean moved to Busan from other places. At that time, UN troops landed on Busan and surrounded Busan to protect Koreans from communists and to defeat North Korea and other allied communists on June 30 in 1950. South Korean and UN Soldiers started to fight with North Korean and communists in Korea. The Korean War occurred when the Korean government was made into Republic of Korea and Democratic People’s Republic of Korea because of political ideology after Pacific War and World War 2. IN 1995, the name of city was changed from Busan City (Jikhalsi) to Busan Metropolitan City.
