Taiwan is highly diversified in terms of religious faith, with the practice of Buddhism, Daoism, Christianity, Mormonism, the Unification Church, Islam, and Hinduism, as well as native sects such as Yiguandao and others.
The island not only respects traditional faiths but also opens its arms to other types of religious thought from the outside. For the most part, the traditional religions practiced in Taiwan are Buddhism, Daoism, and folk religions; except for a small number of purely Buddhist temples, however, most of the island's traditional places of worship combine all three traditions. Daoism is China's native religion, and many of its gods are deified persons who actually lived in the past and made important contributions to society. Guan Gong, the God of War, is a classic example of this; in history he was Guan Yu, a famous general of the Three Kingdoms period. Daoism came to Taiwan in the 17th century, but it was suppressed during the period of Japanese occupation (1895-1945) because of its embodiment of the spirit of Chinese culture. During those years the adherents of Daoism had to worship their gods surreptitiously in Buddhist temples, and after the island was restored to Chinese rule the convergence of these two religions continued. Today all sorts of different kinds of deities are worshipped in the same temple, forming one of the unique features of religion in Taiwan.
Confucius is another important part of religious thinking in Taiwan. Confucius was China's most famous and beloved teacher, advocating the practice of rituals and the worship of ancestors. The Emperor Yuan of the Western Han Dynasty (207 B.C. - A.D. 24) built the first shrine dedicated to Confucius, and after that many more temples were constructed as a mark of respect to the Sage. External religions first arrived on the island in the early part of the 17th century, when Catholicism and Protestantism were introduced by Spanish and Dutch missionaries. Presbyterianism is perhaps the Protestant branch of Christianity that has played the most prominent role in Taiwan's history.
