赫連勃勃
The city was built by around 100,000 Xiongnu of the Hu Xia dynasty under the command of Helian Bobo (Emperor Wulie) in 419. Helian Bobo, also known by his sinified surname as Liu Bobo, was a descendant of the Xiongnu "chanyu" who founded their steppe empire in the 3rd century BC. Helian Bobo died in 425 AD, and Helian Chang succeeded him as ruler of the city.
