Guo Zhang

Guo Zhang (died between July 291 and 7 May 300) was a politician of the Western Jin. He was a maternal relative of Empress Jia, and after she took power in 291, he and Empress Jia's nephew, Jia Mi, wielded significant power over the imperial court. Guo Zhang and Jia Mi were known by the people of their time as "Jia-Guo" (賈郭), and under the two, the Jin government became increasingly corrupt. Provided by Wikipedia
