There were several main reasons why Emperor Taizong of the Tang Dynasty deposed Li Chengqian. First of all, Li Chengqian's character was corrupt and he lost the trust and respect of his father and his subjects. He did not obey his father's orders, did not respect his teachers, did not care about political affairs, indulged in wine, sex, and pleasure, wasting the country's financial and material resources. He had also befriended some crafty people and listened to their instigation, betraying his father and country. Secondly, Li Chengqian's rebellion violated his father's bottom line and endangered the country's security and stability. Not only did he want to assassinate his brothers and ministers, but he also wanted to overthrow his father's rule and seize the throne. Such behavior made Tang Taizong think that Li Chengqian could not be a qualified successor. Therefore, Emperor Taizong abolished Li Chengqian's position as Crown Prince.
