With a tyrannical second emperor - Emperor Yang, the Sui Dynasty was often compared to the Qin Dynasty (221 BC - 206 BC). However, the whole nation was reunified and certain economic and political advances were achieved in the period.In Northern Zhou (557 - 581), Yang Jian, who was born to the noble class and was the Chengxiang (Prime Minister) of the last emperor, monopolized the political and military power and suppressed the separatist forces as well as some other royal forces. In 581, Yang Jian replaced Northern Zhou with Sui and proclaimed himself Emperor Wen. Thus the Sui Dynasty was founded, with Chang'an (currently Xian) the capital and Luoyang the auxiliary capital. In 589, the Sui Court defeated the last of the Southern Dynasties, Chen, and unified the whole nation.
