Busan

Busan Metropolitan City, also known as Pusan is the largest port city in South Korea. Busan has a population of 3.65 million and is South Korea's second largest metropolis, after Seoul. The city is located on the Southeasternmost tip of the Korean Peninsula and faces the Korea Strait. The most densely built up areas of the city are situated in a number of narrow valleys between the Nakdong River and Suyeong River, with mountains separating some of the districts. Administratively, it is designated as a Metropolitan City. The Busan metropolitan area is divided into 15 major administrative districts and a single county.

History
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.
