During the Spring and Autumn (770BC-476BC) and Warring States (475BC -221BC) period (also known as the Eastern Zhou Dynasty), Chinese society went through a

remarkably liberal period of cultural and intellectual openness in which a "Hundred Schools of Thought" (chu-tzu pai-chia, or "all philosophers hundred schools") was encouraged. It was during this period that Taoism, Confucianism, Mohism and Legalism (Fa-chia, or "School of law"), the four main schools of philosophical thought at the time, emerged. They exerted a profound influence on Chinese culture that would reach far into the future. In 550BC, in the middle of the Hundred Schools of Thought era, Lao-tzu wrote the Tao-Te Ching, thus founding Taoism. But the Taoism of the period was far removed from the later, more codified Taoism of Zhang Daoling and others. Still, Taoism pays homage to Lao-tzu as the founder of Chinese Taoism and continues to address him respectfully as Senior Lord Taishang.
Scripture
Tao Te Ching
The Tao Te Ching, or Daodejing, is widely considered to be the most influential Taoist text. It is a foundational scripture of central importance in Taoism. It has been used as a ritual text throughout the history of religious Taoism. However, the precise date that it was written is the subject of debate: there are those who put it anywhere from the 6th century BC to the 3rd century BC.
Zhuangzi
The Zhuangzi was named after its author, who also appears as a character in the book's narrative. It is more in the form of a collection of stories than the short aphorisms and maxims of the Tao Te Ching. Also among the cast of characters in the Zhuangzi's stories is Laozi of the Tao Te Ching, as well as Confucius.
Daozang
The Daozang (Treasury of Tao) is sometimes referred to as the Taoist canon. It was originally compiled during the Jin, Tang, and Song dynasties. The version surviving today was published during the Ming dynasty. The Ming Daozang includes almost 1500 texts. The Zhen ("real" or "truth") grotto includes the Shangqing texts.
Influence
The number of people practicing Chinese folk religion is estimated to be just under four hundred million. Most Chinese people and many others have been influenced in
some way by Taoist tradition. Estimates for the number of Taoists worldwide range from twenty to over fifty million. Geographically, Taoism flourishes best in regions populated by Chinese people: mainland China, Taiwan, Malaysia, Singapore, and various Chinese diaspora communities. Taoist literature and art has influenced the cultures of Korea, Japan, and Vietnam. Organized Taoism seems not to have attracted a large non-Chinese following, except in Korea and Vietnam, until modern times. In Taiwan 7.5 million people (33% of the population) identify themselves as Taoists. In Singapore, 8.5% of the population identify themselves as Taoist. There are also small numbers of Taoists in the Western world.
Relations with Other Religions and Philosophies
Early Taoist texts reject the basic assumptions of Confucianism which relied on rituals and order, in favour of the examples of "wild" nature and individualism. Historical Taoists challenged conventional morality, while Confucians considered society debased and in need of strong ethical guidance.
The entry of Buddhism into China was marked by interaction and syncretism, with Taoism in particular. Originally seen as a kind of "foreign Taoism", Buddhism's scriptures were translated into Chinese using the Taoist vocabulary. Chan Buddhism was particularly modified by Taoism, integrating distrust of scripture, text and even language, as well as the Taoist views of embracing "this life", dedicated practice and the "every-moment". Taoism incorporated Buddhist elements during the Tang period, such as monasteries, vegetarianism, prohibition of alcohol, the doctrine of emptiness, and collecting scripture in tripartite organisation.
Ideological and political rivals for centuries, Taoism, Confucianism, and Buddhism deeply influenced one another. They also share some similar values, with all three embracing a humanist philosophy emphasizing moral behavior and human perfection. In time, most Chinese people identified to some extent with all three traditions simultaneously. This became institutionalized when aspects of the three schools were synthesized in the Neo-Confucian school.
