北元
During the Yuan dynasty, which ruled the whole of China proper, there were several seals. Biligtü Khan (Emperor Zhaozong) of the Northern Yuan dynasty had an imperial seal with the script "Great Yuan". In the 16th century, the Mongols used a square-shaped seal. When the Northern Yuan dynasty collapsed in 1635, Ejei Khan gave one of those seals to the Later Jin dynasty, which later became the Qing dynasty in 1636.
