On October 1, 1949, Mao proclaimed the foundation of the PRC, a single-party state controlled by the CCP. In the following years he solidified his control through campaigns against landlords, suppression of "counter-revolutionaries", "Three-anti and Five-anti Campaigns" and through a psychological victory in the Korean War
From 1953 to 1958, Mao played an important role in enforcing planned economy in China, constructing the first Constitution of the PRC, launching the industrialisation program, and initiating the "Two Bombs, One Satellite" project.
With this success, Mao launched the "Great Leap Forward." He wanted to make the communes larger and more productive.
