Abolition of the presidency in China

The dispute over the abolition of the presidency of the People's Republic of China (formerly called Chairman of the PRC in the 1954 Constitution) led to a broader power struggle between Mao Zedong, Chairman of the Chinese Communist Party, and Marshal Lin Biao, Vice Chairman of the Chinese Communist Party, the Defense Minister and Mao's appointed successor along with some members of the 9th Politburo of the Chinese Communist Party during the middle of the Cultural Revolution. This dispute was later interpreted by the Chinese Communist Party (CCP) as evidence that Lin Biao had tried to usurp the party and seize power.
