张国焘
He rebelled against the Kuomintang after Chiang Kai-shek began violently suppressing Communists, when he planned and led the unsuccessful Nanchang Uprising. After escaping, he organized a soviet in rural Hunan (and later Guizhou), but was forced to abandon his bases when pressured by Chiang's Encirclement Campaigns. He joined the Long March in 1935, over a year after forces associated with Mao Zedong and Zhu De were forced to do so. He met with forces led by Zhang Guotao, but he disagreed with Zhang about the strategy of the Red Army and led his forces to join and support Mao.
