When was Taoism founded?

Taoism was founded in the Spring and Autumn Period and the Warring States Period.

During the Spring and Autumn Period and the Warring States Period, Taoism, as a school in hundred schools of thought, was founded by Lao Zi Li Er. But it was not until the end of the Eastern Han Dynasty that Taoism really developed, and many Taoist organizations were established at this time.

Of the five major religions in China, Taoism is the only one that originated in China and was founded by China people, so it is also called indigenous religion. Taoism had a far-reaching influence on politics, economy and culture in ancient China, and it was one of the three spiritual pillars of the ruling class.
