In the Micronesian Federation, virtually everyone professes Christianity. Missionaries from Hawaii were driving when the Congregationalist Church was established in Kosrae and Pohnpei around 1850. The Christian ideals were integrated with local culture, and the church was then spread by Pohnpeier to the Chuuk Islands. In the 1890s, the Spanish Capuchins founded with great difficulty the Roman Catholic Church at Yap, which today is exclusively Catholic. However, the shift of colonial powers, and thus the changing language of instruction, complicated the situation. The Catholic Church was also established at Pohnpei and Chuuk, and today comprises just over 50% of the population.
