Li Dazhao or Li Ta-chao was a Chinese intellectual and revolutionary who participated in the New Culture Movement in the early years of the Republic of China, established in 1912. He co-founded the Chinese Communist Party (CCP) with Chen Duxiu in July 1921. He helped build a united front between the CCP and Sun Yat-sen's Nationalist Party (KMT) in early 1924. During the Northern Expedition, Li was arrested and then executed by warlord Zhang Zuolin in Beijing in April 1927.

The Chinese Communist Party (CCP), officially the Communist Party of China (CPC), is the founding and sole ruling party of the People's Republic of China (PRC). Under the leadership of Mao Zedong, the CCP emerged victorious in the Chinese Civil War against the Kuomintang. In 1949, Mao proclaimed the establishment of the People's Republic of China. Since then, the CCP has governed China and has had sole control over the People's Liberation Army (PLA). Successive leaders of the CCP have added their own theories to the party's constitution, which outlines the party's ideology, collectively referred to as socialism with Chinese characteristics. As of 2023, the CCP has more than 98 million members, making it the second largest political party by membership in the world after India's Bharatiya Janata Party.
