Yuan Hao
In spring and early summer 529, Liang troops under Chen pushed into Northern Wei territory. Not far away was a large Northern Wei army commanded by the general Yuan Tianmu (元天穆) the Prince of Shangdang. However, Yuan Tianmu did not consider Yuan Hao a threat, and he instead proceeded to attack another rebel leader, Xing Gao (邢杲), who had claimed the title of Prince of Han. Yuan Tianmu and Erzhu Rong's nephew Erzhu Zhao were able to crush Xing and capture him. Meanwhile, however, Chen was able to win battle after battle against Northern Wei generals with much larger forces, and after Chen captured Suiyang, Yuan Hao declared himself emperor there. Chen's army then proceeded to capture Yingyang (滎陽, in modern Zhengzhou, Henan), not far from Luoyang, and when Yuan Tianmu, realizing the seriousness of the Yuan Hao threat, advanced on Yingyang, intending to crush Chen's army, Chen defeated him, forcing him to flee. Yuan Hao then approached Luoyang. Emperor Xiaozhuang, fearful of Yuan Hao's army, fled Luoyang north of the Yellow River to rendezvous with Erzhu Rong and Yuan Tianmu. Yuan Hao was welcomed into Luoyang, whose people were resentful of Erzhu Rong and therefore hoped that Yuan Hao could deliver them. Most of the provinces south of the Yellow River also declared allegiance to him, while most of the provinces north of the Yellow River continued to recognize Emperor Xiaozhuang.
