Emperor Huizong (November 2, 1082 – June 4, 1135) was the eighth and one of the most famous emperors of the Song Dynasty of China, with a personal life spent amidst luxury, sophistication and art but ending in tragedy.
Born Zhao Ji, he was the 11th son of Emperor Shenzong. In February 1100 his older half-brother Emperor Zhezong died without a surviving son, and Huizong succeeded him the next day as emperor. He reigned from 1100 to 1126.
Huizong was famed for his promotion of Taoism. He was also a skilled poet, painter, calligrapher, and musician. He sponsored numerous artists at his court, and the catalogue of his imperial painting collection lists over 6,000 known paintings.
