Cheondoism (Korean Cheondogyo; hanja 天道教; hangul 천도교; literally "Religion of the Heavenly Way") is Korean traditional religion which began during the last year of Joseon Dynasty. It was found in 1860 by Choe Je-U, the first religious sect leader of Cheondoism. At first, he named this religion Donghak, or Eastern Learning in opposition to Western Learning. In 1905, the name was change to Cheondogyo by the third leader, Son Byeong-Hui. In period of Japanese occupation, it made an effort to lead Korea's Independence Movement against Japanese colonial rule and expand it's congregation. Today, Cheondoism exerts less strong influence than before.
