not captured by the North Korean army within the first three months of the War. As a result, the city became a refugee camp site for Koreans during the war. As Busan was one of the few areas in Korea that remained under the control of South Korea throughout the Korean War, for some time it served as a temporary capital of the Republic of Korea. UN troops established a defensive perimeter around the city known as the Pusan Perimeter in the summer and autumn of 1950. Since then, like Seoul, the city has been a self-governing metropolis and has built a strong urban character. From 1978, three container port docks were opened and in 2013, Busan is the third port in the world due to its facilities and overall capacity.
