A series of violent riots over several days broke out on 5 July 2009 in Ürümqi, the capital city of the Xinjiang Uyghur Autonomous Region (XUAR), in northwestern China. The first day's rioting, which involved at least 1,000 Uyghurs, began as a protest, but escalated into violent attacks that mainly targeted Han people. According to Chinese state media, a total of 197 people died, most of whom were Han people or non-Muslim minorities, with 1,721 others injured and many vehicles and buildings destroyed. Many Uyghurs disappeared during wide-scale police sweeps in the days following the riots; Human Rights Watch (HRW) documented 43 cases and said figures for real disappearances were likely to be much higher.

Rebiya Kadeer is an ethnic Uyghur businesswoman and political activist. Born in Altay City, Xinjiang, Kadeer became a millionaire in the 1980s through her real estate holdings and ownership of a multinational conglomerate. Kadeer held various positions in the National People's Congress in Beijing and other political institutions before being arrested in 1999 for, according to Chinese state media, sending confidential internal reference reports to her husband, who worked in the United States as a pro-East Turkistan independence broadcaster. After she fled to the United States in 2005 on compassionate release, Kadeer assumed leadership positions in overseas Uyghur organizations such as the World Uyghur Congress.
