James Hannington, born 1847, was sent out from England in 1884 by the Anglican Church as missionary Bishop of Eastern Equatorial Africa. As he was travelling toward Uganda, he was apprehended by emissaries of King Mwanga. He and his companions were brutally treated and, a week later, 29 October 1885, most of them were put to death. Hannington's last words were: "Go tell your master that I have purchased the road to Uganda with my blood."
The first native martyr was the Roman Catholic Joseph Mkasa Balikuddembe, who was beheaded after having rebuked the king for his debauchery and for the murder of Bishop Hannington. On 3 June 1886 (see Biography), a group of 32 men and boys, 22 Roman Catholic and 10 Anglican, were burned at the stake. Most of them were young pages in Mwanga's household, from their head-man, Charles Lwanga, to the thirteen-year-old Kizito, who went to his death "laughing and chattering." These and many other Ugandan Christians suffered for their faith then and in the next few years.
In 1977, the Anglican Archbishop Janani Luwum and many other Christians suffered death for their faith under the tyrant Idi Amin.
Thanks largely to their common heritage of suffering for their Master, Christians of various communions in Uganda have always been on excellent terms.
