Chiang Kai-Shek and Mao Zedong were two of the most prominent leaders of China in the twentieth century and had lasting impressions on Chinese governance. Chiang, also known as Generalissimo, was a disciple of Sun Yat-Sen and received military education. He led China for several years. He was the leader of Kuomintang, the Nationalist Party, and unified the country as he led the Republic of China for 22 years. After Mao Zedong's victory, Chiang Kai-Shek retreated to Taiwan and ruled for a further 30 years.
Mao Zedong was a communist and was at loggerheads with Chiang Kai-Shek. He led the Chinese Communist Party to a victory against the Nationalist Party of Chiang Kai-Shek and established the People's Republic of China, the form in which we see China today.
Chiang Kai-Shek and Mao Zedong had differing philosophies; their only common concern was the establishment of the Republic of China, a unified country free from foreign oppression. They briefly came together against the threat of Japan; apart from that, their ideological differences kept them as enemies.
