Mao was born in Chaochan in Hunan province. He came from a peasant family. As with all peasants living in Nineteenth Century China, his upbringing was hard and he experienced no luxuries.
He first encountered Marxism while he worked as a library assistant at Peking University. In 1921, he co-founded the Chinese Communist Party. Mao gave a geographic slant to Marxism as he felt that within an Asiatic society, communists had to concentrate on the countryside rather than the industrial towns. In reality, this was a logical belief as China had very little industry but many millions involved with agriculture. Mao believed that a revolutionary elite would only be found in the peasantry and not among those who worked in towns.
With Zhou Enlai, Mao established a revolutionary base on the border of Hunan. In 1931, Mao set up a Chinese Soviet republic in Kiangsi. This lasted until 1934 when Mao and his followers were forced to leave Kiangsi and head for Shensi in the legendary Long March which lasted to 1935. Here they were relatively safe from the Kuomintang lead by Chiang Kai-shek but far removed from the real seat of power in China – Peking (Beijing).
From 1937 to 1945, the enmity between the KMT and the Communists was put to one side as both concentrated their resources on the Japanese who had launched a full-scale invasion of China in 1937. It was during this time that Mao developed his knowledge about guerrilla warfare that he was to use with great effect in the civil war against the KMT once the war with Japan had ended in 1945.
