The ninth patriarch Huang De-hui founded Xian Tian Tao in 1661, laying a foundation for I-Kuan Tao. In 1877, the 15th patriarch Wang Jue Yi advocated the Interconnection of the Three Realms of Heaven: Wu-Ji Li Tien (the Ultimate Truth Heaven), Tai-Ji Energy Heaven and Huang-Ji Phenomena Heaven and utilizes them to complete the constitution of Confucius philosophy as I-Kuan Tao’s core teaching. In 1886, the 16th patriarch Liu Qing Xü officially named the great Tao “I-Kuan Tao”. I-Kuan Tao was steadily progressed under the leadership of the 17th patriarch Lu Zhong-Yi. Afterward, it was spreaded from China to Taiwan and to the rest of the world by the 18th Patriarch Zhang Tian-Ran and Matriarch Sun Su-Zhen. The I-Kuan Tao societies spread now over 80 countries around the globe, and its national headquarters had been established in 14 countries. The I-Kuan Tao International Headquarter was founded in America.
