In the 1860s, while Arabs sought influence from the north, British explorers searching for the source of the Nile arrived in Uganda. They were followed by British Anglican missionaries who arrived in the kingdom of Buganda in 1877 and French Catholic missionaries in 1879. This situation gave rise to the death of the Uganda Martyrs in 1885—after the conversion of Muteesa I and much of his court, and the succession of his anti-Christian son Mwanga.
