The Proto–Three Kingdoms period (or Samhan period) refers to the proto-historical period in the Korean Peninsula, after the fall of Gojoseon and before the maturation of Goguryeo, Baekje, and Silla into full-fledged kingdoms. It is a subdivision of what is traditionally called Korea's Three Kingdoms period and covers the first three centuries of the Common Era, corresponding to the later phase of the Korean Iron Age.
