nLaozi was an ancient Chinese philosopher and writer. He is known as the reputed author of the Tao Te Ching and the founder of philosophical Taoism, and as a deity in religious Taoism and traditional Chinese religions. Although a legendary figure, he is usually dated to around the 6th century BC and reckoned a contemporary of Confucius, but some historians contend that he actually lived during the Warring States period of the 5th or 4th century BC. A central figure in Chinese culture, Laozi is claimed by both the emperors of the Tang dynasty and modern people of the Li surname as a founder of their lineage. Laozis work has been embraced by various anti-authoritarian movements as well as Chinese Legalism.
