Han Dynasty

Han empire began in 206 B.C. when Liu Bang, prince of Han, defeated the Qin army in the valley of Wei. The defeat was part of a larger rebellion that began after the First Emporer's death. The people were dissatisfied with the tyranny of the Qin leaders and their Legalist form of government. However, while traditional Chinese history portrays the Han as implementing immediate changes in government, evidence shows the Han continued to rule in the tradition of the Qin, and only gradually incorporated Confucian ideals into their Legalist form of government. Economic expansion, changing relationships with the people of the steppes, strengthening of the palace at the expense of the civil service, weakening of the state's hold on the peasantry, and the rise of the families of the rich and the gentry were all factors that led to the adoption of Confucian ideals..
The expansion also led to trade with the people of inner Asia. Thereafter, the Silk Road was developed. The Silk Road actually consisted of more than one possible route through the mountains that the traders followed. Agriculture grew with the development of better tools. Iron tools were made of better quality, and oxen drawn ploughs were commonly used. Irrigation systems were increased to help develop the areas of North China. Crop rotation was also practiced from 85 B.C. onwards. The state attempted to monopolize the production of iron and salt, which were the two biggest sectors of the economy, but succeeded for less than a century. Silk weaving and copper work were also important activities.
