"In the early 1250s, Mongke Khan, grandson and successor of the mighty Mongol emperor, Genghis Khan, sent out his younger brothers Qubilai and Hulegu to consolidate his grip of power. Hulegu was welcomed into Iran while Qubilai continued to erode the power of the Song emperors of southern China. In 1276, he finally forced their submission and peacefully occupied their capital, Hangzhou. The city enjoyed a revival as the cultural capital of a united China and was soon filled with traders, adventurers, artists, entrepreneurs, and artisans from throughout the great Mongol Empire, including a prosperous, influential and seemingly welcome community of Persians. In 1281, one of their number, Ala al-Din, built the Phoenix Mosque in the heart of the city where it still stands today. This study of the mosque and the Ju-jing Yuan cemetery, which today is a lake-side public park, casts light on an important and transformative period in Chinese history, and perhaps the most important period in Chinese Islamic history"--front flap.
