Yin Hao

Yin Hao (殷浩) (died 356), courtesy name Yuanyuan (渊源), was a Jin Dynasty (265-420) politician.

Yin Hao was from an aristocratic family, and when he was young, he became known for intelligence and metaphysical discussions. He temporarily served on Yu Liang's staff, but subsequently declined an invitation by Yu Liang's younger brother Yu Yi (庾翼) to serve on his staff, and he lived the life of a hermit. Gradually, officials and commoners began to believe that he had the ability to guide the Jin state to great things, and people even observed his behavior to venture guesses as to what the fortunes of the state would be. In 346, he finally agreed to join the government as the governor of the capital region.

In 348, after Huan Wen destroyed Cheng Han and merged its territory into Jin's, key officials of the Jin imperial government began to fear that he would use his military might to try to dominate the government. The regent for Emperor Mu, Sima Yu the Prince of Kuaiji therefore invited Yin to participate in important government decisions. Yin and Huan immediately developed a rivalry and suspected each other of treachery.

In 350, intent on proving himself as much of a general as Huan, Yin had himself commissioned with a large army, preparing to recover central and northern China as rival Later Zhao was collapsing into civil war, but for reasons unknown delayed the campaign. Later that year, he took even greater power, as after another major official, Cai Mo (蔡謨), repeatedly declined an imperial honor, he accused Cai of being disrespectful and had Cai imprisoned. He was prepared to further execute Cai, but was persuaded not to, but Cai was still demoted to commoner status.

Around the new year 352, Huan, upset that his requests to lead armies north had been rebuffed by Yin and Sima Yu, mobilized his troops and gestured as if he were about to attack the capital. Yin was shocked, and initially considered either resigning or send the imperial banner of peace (Zouyu Fan, 騶虞幡) to order Huan to stop. After advice from Wang Biaozhi (王彪之), however, he instead asked Sima Yu to write a carefully worded letter to Huan, persuading Huan to stop.

Later in 352, Yin launched his own campaign, but upon the start of the campaign, former Later Zhao generals in control of Xuchang and Luoyang rebelled, and his venture had to halt to deal with these rebellions. Subsequently, when his assistants, the generals Xie Shang (謝尚) and Yao Xiang (姚襄) tried to attack Zhang Yu (張遇), the general in control of Xuchang, Former Qin forces came to Zhang's aid and defeated Xie's troops. Yin then abandoned the campaign entirely.
