The Chinese Communist Party, which formed in 1921 and has ruled the People's Republic of China since 1949, celebrated its 100th anniversary on Thursday, July 1.
As the ruling party, the CCP monopolizes both the state and society in China. It controls the military and the police, along with personnel appointments across all of China's political institutions, the media and the judiciary.
With more than 90 million members, the CCP is one of the largest political parties in the world.
The party's leader, Xi Jinping, has been China's President since 2013. A controversial change to the country's constitution abolished term limits in 2018, paving the way for Xi to stay in power indefinitely.
