Zebras have been kept in captivity since at least the Roman Empire. In later times, captive zebras have been shipped around the world, often for diplomatic reasons. In 1261, Sultan Baibars of Egypt established an embassy with Alfonso X of Castile and sent a zebra and other exotic animals as gifts. In 1417, a zebra was sent to the Yongle Emperor of China from Somalia as a gift for the Chinese people. The fourth Mughal emperor Jahangir received a zebra from Ethiopia in 1620 and commissioned a painting of the animal, which was completed by Ustad Mansur. In the 1670s, Ethiopian Emperor Yohannes I exported two zebras to the Dutch governor of Jakarta. These animals would eventually be given by the Dutch to the Tokugawa Shogunate of Japan.
