The Yuan dynasty started in 1260 when Genghis Khan's grandson, Kublai Khan became the emperor of China. Kublai Khan was the first outsider to rule China. To make the Chinese like him he moved the capital from Mongolia to a city which is close to today's Beijing. But only non-Chinese could have high government positions.
