Joseph Mukasa was a 19th-century majordomo serving the court of King Mwanga II in the Buganda kingdom. Born around 1860 in Mawokota County, he became a Catholic catechumen in 1879 and was baptized in 1882. During a period when missionaries had temporarily relocated for safety, he served as a leader for the local Christian community. His commitment to his faith and his attempts to intercede for others eventually led to his execution in Kasubi in 1885.
