What is "hanpu"

Hanpu or Hambo , later Wanyan Hanpu, was a leader of the Jurchen Wanyan clan in the early tenth century. According to the ancestral story of the Wanyan clan, Hanpu came from Goryeo ( Korea) when he was sixty years old, reformed Jurchen customary law, and then married a sixty-year-old local woman who bore him three children. His descendants eventually united Jurchen tribes into a federation and established the Jin dynasty in 1115. In 1136 or 1137, Hanpu was retrospectively given the temple name Jin Shizu , or "first ancestor of Jin."

Chinese historians have long debated whether Hanpu was of Silla, Goryeo, or Jurchen ethnicity. Since the 1980s, they have chiefly argued that he was a Jurchen who had lived in Silla, the state that had dominated the Korean peninsula until it was destroyed by Goryeo in 935. Western scholars usually treat Hanpu's story as a legend, but agree that it hints to contacts between some Jurchen clans and the states of Goryeo and Balhae (a state located between Jurchen lands and Silla until it was destroyed in 926) in the early tenth century. In Korea, a recent KBS history special treated Hanpu as a native Silla man who moved north and settled in Jurchen lands during the demise of Silla.
