Li Hong

Li Hong was a crown prince of the Tang dynasty of China. He was the fifth son of Emperor Gaozong and the eldest son of his second wife Empress Wu. After being titled Prince of Dai (代王) in 655, he became crown prince in 656. As he grew older, he often came in conflict with his ambitious and powerful mother and it is believed by traditional historians that she poisoned him to death in 675. His father Emperor Gaozong, then still reigning, posthumously honored him with an imperial title.
