Centralisation or centralization (see spelling differences) is the process by which the activities of an organization, particularly those regarding planning and decision-making, framing strategy and policies become concentrated within a particular geographical location group. This moves the important decision-making and planning powers within the center of the organisation. The term has a variety of meanings in several fields. In political science, centralisation refers to the concentration of a government's power—both geographically and politically—into a centralised government. Centralisation of authority is defined as the systematic and consistent concentration of authority at a central point or in a person within the organization. This idea was first introduced in the Qin Dynasty of China. The Qin government was highly bureaucratic and was administered by a hierarchy of officials, all serving the First Emperor, Qin Shi Huang. The Qin Dynasty practised all the things that Han Feizi taught, allowing Qin Shi Huang to own and control all his territories, including those conquered from other countries. Zheng and his advisers ended feudalism in China by setting up new laws and regulations under a centralized and bureaucratic government with a rigid centralization of authority. Under this system, both the military and government thrived. This was because talented individuals were more easily identified and picked out to be trained for specialized functions.
