Traditional Chinese law refers to the laws, regulations and rules used in China up to 1911, when the last imperial dynasty fell. It has undergone continuous development since at least the 11th century BC. This legal tradition is distinct from the common law and civil law traditions of the West – as well as Islamic law and classical Hindu law – and to a great extent, is contrary to the concepts of contemporary Chinese law. It incorporates elements of both Legalist and Confucian traditions of social order and governance.
