Gija Joseon rulers

Jizi or Qizi or Kizi (Chinese: 箕子; Wade–Giles: Chi-tzu; Gija or Kija in Korean) was a semi-legendary Chinese sage who is said to have ruled Gija Joseon in the 11th century BCE. Early Chinese documents like the Book of Documents and the Bamboo Annals described him as a virtuous relative of the last king of the Shang dynasty who was punished for remonstrating with the king. After Shang was overthrown by Zhou in the 1040s BCE, he allegedly gave political advice to King Wu, the first Zhou king. Chinese texts from the Han dynasty (206 BCE – 220 CE) onwards claimed that King Wu enfeoffed Jizi as ruler of Chaoxian (朝鮮, pronounced "Joseon" in Korean). According to the Book of Han (1st century CE), Jizi brought agriculture, sericulture, and many other facets of Chinese civilization to Joseon.
