Who was the fifteenth emperor of the Tang Dynasty?

Tang Wuzong-Li Yan (born in August14, died in 846) was the 15 th emperor of the Tang Dynasty (together with Wu Zetian). He was in office from 840 to 846, and he was in office for 6 years, aged 33. Tang Wuzong was Tang Wenzong's younger brother named Wang Ying. Under the control of eunuch Chou Shiliang, he was made Emperor Taidi by taking advantage of the illness of literate Sect, and the former Prince Li was abolished and was able to reign. Tang Wuzong believes in Taoism. Since 845, a large-scale suppression of Buddhism has been ordered, which is called Huichang's suppression of the law. Except for a few temples in the capital, all the temples in the country were demolished, monks and nuns were forced to return to the secular world, the slaves in the temples were released, and all the fields in the temples were confiscated as state-owned. This is a serious blow to Buddhism in the history of China. In the history of the Tang Dynasty, there has always been dissatisfaction with the forces of Buddhism. There may be many reasons for the extinction of Buddhism in Tang Wuzong. First of all, perhaps because Tang Wuzong himself believed in Taoism more, he attacked Buddhism. Besides, Buddhism was very powerful at that time. Tang Wuzong said in his will that the scale of Buddhist temples is larger than that of the imperial palace, and the temples do not pay taxes, which is a great loss to the national finance. Finally, there is a legend that after Tang Wuzong succeeded to the throne, he was afraid that someone would frame his uncle Li Chen (later Tang Xuanzong) and threaten his position. Li Chen fled to the Buddhist country, so Tang Wuzong destroyed the Buddha and left Li Chen with nowhere to hide. But this statement may be just a legend, because historians are still controversial about whether Li Chen was really a monk. Tang Wuzong died of poisoning after eating the longevity pills given to him by the Taoist priest. Tang Wuzong was buried in Duanling after his death, and posthumous title was the most filial emperor.
