The history of Taoism stretches throughout Chinese history. Originating in prehistoric China, it has exerted a powerful influence over Chinese culture throughout the ages. Taoism evolved in response to changing times, with its doctrine and associated practices being revised and refined. The acceptance of Taoism by the ruling class has waxed and waned, alternately enjoying periods of favor and rejection. Most recently, Taoism has emerged from a period of suppression and is undergoing a revival in China.
Laozi (Lao Tzu) is traditionally regarded as the founder of the Taoist religion and is closely associated in this context with "original", or "primordial", Taoism. Whether he actually existed is disputed, and the work attributed to him – the Daodejing (Tao Te Ching) – is dated between the 8th and 3rd century BC. The Yellow Emperor, Huangdi (2697–2597 BCE) is also often associated with the origin of the Tao; his works are believed to have greatly influenced Laozi. It is possible Taoism existed before Laozi, as he refers to the "Tao masters of antiquity" in the 15th chapter of the Daodejing; however it is also possible he was referring to masters—mythical or historical—of the wisdom to which Taoism points, rather than masters of Taoism as an already established religion.
