In short
On July 23, 1921, a small group of Chinese intellectuals and activists gathered in Shanghai to formally establish the Communist Party of China. The party emerged from decades of turmoil following China's military defeats and colonial encroachment, offering a radical alternative to both traditional governance and the competing Nationalist movement. This founding set in motion the ideological and organizational machinery that would eventually seize power nearly three decades later.
How it unfolded.
The five-minute version
What actually happened.
The Communist Party of China (CPC), commonly known as the Chinese Communist Party (CCP), is the founding and ruling party of the People's Republic of China (PRC). Founded in 1921, the CCP won the Chinese Civil War against the Kuomintang and proclaimed the establishment of the PRC under the chairmanship of Mao Zedong in October 1949. The CCP has since governed China and has had sole control over the country's armed forces and law enforcement. As of 2024, the CCP has more than 100 million members, making it the second largest political party by membership in the world.
