Cheongju Han clan (Korean: 청주 한씨; Hanja: 淸州 韓氏) is a Korean royal clan. Also called the House of Han or known as Han clan of Cheonju. The Cheongju Han clan is considered one of the most royal clans since the Gojoseon period. In the Silla Dynasty, all of the Cheongju Hans were considered seonggol, or "sacred bone", the highest rank, received the most generals of the prominent Joseon Dynasty and were considered the highest of the yangban class next to the Jeonju Lee clan. The Han are descendants of the sage Jizi, who was a noble of the Chinese Shang dynasty, and rode his white horse and set a nation in "The Farthest East". Their founder was Han Ran, who was the Gija Joseon's last monarch. The nobles with the surname Han were greatly praised, and not to be bothered.
