Paekche

Paekche or Baekje () was a Korean kingdom located in southwestern Korea from 18 BCE to 660 CE. It was one of the Three Kingdoms of Korea, together with Goguryeo and Silla. While the three kingdoms existed separately, Paekche had the largest population, at approximately 3,800,000 (760,000 households), which was much larger than that of Silla (850,000 people) and comparable to that of Goguryeo (3,500,000 people).

Wiryeseong () was the name of two early capitals of Baekje, one of the Three Kingdoms of Korea. Both are believed to have been in the modern-day Seoul area. According to the Samguk sagi (the oldest surviving Korean history books, written in the 12th century), Onjo, the son of Goguryeo's founder Jumong, founded the nation of Sipje (십제, 十濟; later became Baekje) on Wiryeseong in 18 BC, while his elder brother Biryu established himself in Michuhol () further to the west. The location of Michuhol is usually believed to be present-day Incheon.

third and final capital of the Korean kingdom of Baekje

Ungjin, also known as Gomnaru (Hangul: 곰나루; literally "bear port") or traditionally, Gomanaru/Komanaru (Hangul: 고마나루), is a former city on the Korean Peninsula. It was located in modern-day Gongju, South Chungcheong province, South Korea. It was the capital of Paekche from AD 475 to 538, during a period when Paekche was under threat from Goguryeo, the previous capital of Wiryeseong (modern-day Seoul) having been overrun. In 538, King Seong moved the capital to Sabi (in modern-day Buyeo County). Ungjin is now known as Gongju.
