Emperor Taiwu of Northern Wei

Emperor Taiwu of Northern Wei, personal name Tuoba Tao (拓拔燾), Xianbei name Büri (佛貍), was an emperor of Northern Wei. He was generally regarded as a capable ruler, and during his reign, Northern Wei roughly doubled in size and united all of northern China, thus ending the Sixteen Kingdoms period and, together with the southern dynasty Liu Song, starting the Southern and Northern Dynasties period of ancient Chinese history. He was a devout Taoist, under the influence of his prime minister Cui Hao, and in 444, at Cui Hao's suggestion and believing that Buddhists had supported the rebellion of Gai Wu (蓋吳), he ordered the abolition of Buddhism, at the penalty of death. This was the first of the Three Disasters of Wu for Chinese Buddhism. Late in his reign, his reign began to be cruel, and his people were also worn out by his incessant wars against Liu Song. In 452, he was assassinated by his eunuch Zong Ai, who put his son Tuoba Yu on the throne but then assassinated Tuoba Yu as well. The other officials overthrew Zong and put Emperor Taiwu's grandson Tuoba Jun on the throne as Emperor Wencheng.
