衛氏朝鮮
According to the Records of the Grand Historian by the Chinese historian Sima Qian, Wiman Joseon of Korea was founded by General Wiman from China who originally served but usurped the throne of Gojoseon (the name of ancient Korea) in 194 BC. In 108 BC, the Han dynasty of China destroyed Wiman Joseon and established four commanderies on the northern Korean peninsula. Three of the commanderies were shortly lost but the Lelang commandery remained on the northwestern Korean peninsula for about 400 years. The Three Kingdoms of Korea of Baekje, Goguryeo and Silla emerged after the fall of Gojoseon and eventually expelled the Chinese. The Three Kingdoms competed with each other both economically and militarily; Goguryeo and Baekje were the main players for much of the Three Kingdoms era and controlled most of the Korean peninsula. At times more powerful than neighboring Chinese dynasties, Goguryeo (where the name "Korea" comes from) was a regional power that defeated massive invasions by the Sui dynasty multiple times. Goguryeo and Baekje were eventually destroyed by a Tang dynasty and Silla alliance. Silla then drove out the Tang dynasty in 676 to control most of the Korean peninsula undisputed.
