As we all know, the Zhengde Emperor of China (who reigned from 1505 to 1552) publicly converted to Islam after his near-death experience in 1521, but what if he hadn't openly converted to Islam (or died in 1521)? What would the impact be of no Muslim Ming Emperors? Would Islam still be a prominent religion in China (with 13% of China's population being Muslims histroically)? What would the Ming Dynasty's fate be if the Zhengde Emperor hadn't adopted Islam?
