Wang Jingwei (Wang Ching-wei; 4 May 1883 10 November 1944; born as Wang Zhaoming (Wang Chao-ming), but widely known by his pen name Jingwei ( Ching-wei )), was a Chinese politician. He was initially a member of the left wing of the Kuomintang (KMT), but later became increasingly anti-Communist after his efforts to collaborate with the CCP ended in political failure. His political orientation veered sharply to the right later in his career after he joined the Japanese.Wang was a close associate of Sun Yat-sen for the last twenty years of Sun's life. After Sun's death Wang engaged in a political struggle with Chiang Kai-shek for control over the Kuomintang, but lost. Wang remained inside the Kuomintang, but continued to have disagreements with Chiang until the break of The Second Sino-Japanese War in 1937, after which he accepted an invitation from the Japanese Empire to form a Japanese-supported collaborationist government in Nanjing. Wang served as the head of state for this Japanese puppet government until he died, shortly before the end of World War II. Although he is still regarded as an important contributor in the Xinhai Revolution, his collaboration with the Imperial Japanese is a subject of academic debate, and the typical narratives often regard him as a traitor in the War of Resistance.
