The Catholic faith infiltrated Northern Uganda through the work of one of the Verona Fathers; Bishop Daniel Comboni who became the Apostolic Vicar of Khartoum in the Vicariate of Central Africa (in December 1877).After his death in 1881, the Combonimissionaries continued with the work under Bishop Xavier Francis Geyer moving southwards from Bahrel Ghazal through Gondokoro, Nimule until they arrived in Pakwach on the 2nd February 1910. At Nimule on the Uganda-Sudan boarders, they were not allowed to enter Uganda as they could not produce an entry permit except a recommendation from the Governor General of Sudan.
