Martyrs' Day is observed in Uganda every June 3 as a public holiday, commemorating the execution of 23 Anglican and 22 Catholic converts between November 1885 and January 1887 under King Kabaka Mwanga II. The executions, particularly concentrated in Namugongo, took place between May 25 and June 3, 1886, with 22 Catholic converts buried alive. This day serves as a pilgrimage for many, attracting participants from Uganda and neighboring countries such as Kenya, Rwanda, Tanzania, Burundi, and the Democratic Republic of Congo, with the pilgrimage starting on May 25 and culminating on June 3. The climax of the celebrations includes a Mass at 10 a.m., accompanied by liturgical dances, and is attended by ministers and representatives from various embassies and states. The event is organized annually by dioceses, highlighting its significance in Ugandan culture and history.
