Religion

Since Western missionaries brought Christianity to Tongan society, politics, and culture, it has had a significant role in all of these areas. The London Missionary Society started this in the late 1700s, and it lasted into the early 1800s with the help of Free Wesleyan missionaries. Almost every element of life was impacted at this time, including the traditional socio-political system and kin groups. Many native customs, such as the practice of tattooing and indigenous worldviews, that opposed Christianity's morality or ways of life were modified to fit the faith.

Nearly all Tongans today identify with a particular branch of Christianity. In the nation, there is a wide variety of Christian denominations that are practiced, including but not limited to: the Free Wesleyan Church (35%), Church of Jesus Christ and the Latter-day Saints [Mormonism] (18.6%), Roman Catholic Church (14.2%), Free Church of Tonga (11.9%), Church of Tonga (6.8%), Assembly of God (2.3%), Seventh Day Adventist (2.2%), Tokaikolo Christian Church (1.6%), and other Protestant 2.4% of the remaining population identifies as belonging to another religion, and 0.05% do not.
