Busan was the host city of the 2002 Asian Games and APEC 2005 Korea. It was also one of the host cities for the 2002 FIFA World Cup, and is a center for international conventions in Korea. On November 14, 2005, the city officially announced its bid to host the 2020 Summer Olympics Games.

Geochilsan-guk existed in the second and third and fourth centuries as a chiefdom of Jinhan. It was absorbed by Silla and renamed Geochilsan-gun. The word Geochilsan means rough mountain, probably referring to Hwangnyeongsan, located at the center of the city.

The grave goods excavated from mounded burials at Bokcheon-dong indicate that a complex chiefdom ruled by powerful individuals was present in the Busan area just as the Three Kingdoms of Korea were forming, c. A.D. 300-400. The mounded burials of Bokcheon-dong were built along the top of a ridge that overlooks a wide area that makes up parts of modern-day Dongnae-gu and Yeonje-gu. Archaeologists excavated more than 250 iron weapons and ingots from Burial No. 38, a wooden chamber tomb at Bokcheon-dong.

In 757, Geochilsan-gun was again renamed Dongnae, which it is still called.

From the beginning of the fifteenth century, the Korean government designated Busan as a trading port with the Japanese and allowed their settlement. Other Japanese settlements in Ulsan and Jinhae diminished later, but the Busan settlement, called Waegwan at the time, continued until Japan invaded Korea in 1592. After the war, diplomatic relations with the new shogunate in Japan were established in 1607, and Busan Waegwan was permitted to be reconstructed. The Japanese settlement, though relocated into Choryang later, continued to exist until Korea was exposed to modern diplomacy in 1876. In 1876, Busan became the first international port in Korea.

During the Japanese rule, Busan developed into a hub trading port with Japan. Busan was the only city in Korea to adopt the steam tramway before electrification was introduced in 1924[verification needed]. Busan, along with Jeju City, is the only city in Korea, with the exemption of Daegu, that was never taken by the North Korean Communists during the Korean War. As a result the city was a refugee camp site for Koreans during the war.

Busan was one of the few areas in Korea that remained under the control of South Korea throughout the Korean War and 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.

Many restaurants in the area are famous for their family recipes. Chungnyeolsa is a Confucian shrine for soldiers who died during the sixteenth century battle against the Japanese at Dongnae Fortress.

Busan is called the summer capital of Korea since it attracts tourists from all over the country to its six beaches. Luxury hotels and a carnival boardwalk line the beach at Haeundae. Gwangalli Beach is famous for its cafes, bars, and restaurants along the beach, and the Grand Gwangan Bridge. The area around Pukyong National University and Kyungsung University has many cafes, bars and restaurants attracting college students and youth.

Taejongdae, is a natural park with magnificent cliffs facing the open sea on the island of Yeongdo.

The area known as the "Foreigners' Shopping Street", but commonly referred to as "Texas Street" near part of the Port of Busan, has many businesses that cater to the local Russian population, as well as the crews of foreign ships. The area was originally the location of the local Chinatown and still contains a Chinese school. Because of the Chinese presence, the area was designated to serve as the commercial and entertainment needs of American soldiers, and businesses were set up there during the 1940s and 1950s to cater to them.
