He was born in a turbulent time in 181 in Shandong Province. After he was born, a large-scale rebellion of the Yellow Turbans and the Five Pecks of Rice army ravaged the country. Then, when he was 14, Cao Cao invaded Shandong. His family was forced to flee. This was a time of natural disasters, regional conflicts, and political crisis. There were frequent assassinations and open conflicts between rival ruling groups of the dynastic court. In Hubei, he farmed during the day and studied at night. It is said that he developed friendships with the local educated people.
In 207, he met Liu Bei. Liu Bei's base of power was in the region of the southwest around Sichuan. They were threatened by Cao Cao who held a large area north of the Yangtze River. Liu Bei and Zhuge Liang planned an alliance between Liu Bei and a ruler named Sun Quan who controlled a lot of territory in the southeast. In 208, at the Battle of Red Cliffs, the allied armies of Liu Bei and Sun Quan defeated Cao Cao's army.
Due to this victory, both of the southern regions became kingdoms when the Eastern Han Dynasty ended. In the year 220, the empire was divided between the three rival regional leaders. Cao Cao (155¨C220 CE) controlled the area north of the Yangtze River; Liu Bei (161-223) controlled an inland area including Sichuan in the southwest; and Sun Quan (182-252) controlled the southeast. The north was called Cao Wei, the southwest was called Shu Han, and the southeast was called Dong Wu that means Eastern Wu. The Han Empire broke into three economic geographical regions that were separated by the natural boundaries of the Yangtze River and the central mountains where the Three Gorges are. It is said that Zhuge Liang understood the geographical division of the region.
In the southwest, the Shu Han had a small population of only a million people. But they had a natural defensive stronghold because travel by boat going upriver past the Three Gorges area was difficult. The river's passage could be defended against invading armies. Their territory was also very fertile. However, the other states were bigger and more populous. Dong Wu had about twice the population, and Cao Wei had four times their population.
In 221, Liu Bei in Shu Han named himself the Emperor of the Han Empire. In the same year, Sun Quan took the title of the King of Wu. Liu Bei declared war on Dong Wu. At the Battle of Yiling, Liu Bei was defeated by Sun Quan's army, and he was forced to retreat back to Shu Han where he died. After the death of Liu Bei, Liu Bei's son Liu Shan took power in Shu Han. Zhuge Liang became the Prime Minister under Liu Bei. They made peace with Sun Quan. This stabilized the political situation between them. In order to make sure that the Nanmen people who lived in the south would not attack them, Zhuge Liang and Liu Shan fought the Nanmen. Once they surrendered, they added Nanmen to their army. Shu Han was then prepared to attack northwards.
In 227, Zhuge Liang sent an army against Cao Wei even though Wei had a much bigger population. His five campaigns failed, and in 234, he led his last northern offensive. During the campaign, he died of an illness at the age of 54.
