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).
