This is a picture of Kublai Khan, more properly spelled Khubilai Khan, who lived from 1215 to 1294 and built a magnificent summer palace at Xanadu. He moved the capital of the Mongol Empire to a city called Cambaluc, or Khan-balik "Khan's capital" - now called Beijing.

Marco Polo met him and called him Cublay Kaan, describing him as "the most potent man, as regards forces and lands and treasure, that existeth in the world, or ever hath existed from the time of our First Father Adam until this day."
