衛氏朝鮮
King Jun of Gojoseon is reported to have fled to Jin after Wiman seized his throne and established Wiman Joseon. Some believe that Chinese mentions of Gaeguk or Gaemaguk (蓋馬國, Kingdom of armored horses) refers to Jin. Goguryeo is said to have conquered "Gaemaguk" in 26 AD, but this may refer to a different tribe in northern Korea.
