Ulugh Beg, grandson of the Asian conqueror Timur (Tamerlane) and one whose primary interest was in the arts and intellectual matters. Under his brief rule, the Timurid dynasty of Iran reached its cultural peak.
Ulugh Beg was notable for his work in astronomy-related mathematics, such as trigonometry and spherical geometry, as well as his general interests in the arts and intellectual activities. It is thought that he spoke five languages: Arabic, Persian, Turkic, Mongolian, and a small amount of Chinese. During his rule (first as a governor, then outright) the Timurid Empire achieved the cultural peak of the Timurid Renaissance through his attention and patronage. Samarkand was captured and given to Ulugh Beg by his father Shah Rukh.
Ulugh Beg and his astronomical observatory scheme are depicted on the 1987 USSR stamp. He was one of the greatest astronomers during the Middle Ages. The stamp says "Uzbek astronomer and mathematician Ulugbek" in Russian.
