Uganda is coming together to honour the life of King Oyo Nyimba Kabamba Iguru Rukidi IV, the Omukama of the historic Tooro Kingdom, who passed away on 27 August 2026 at the age of 34. The news was officially shared by Tooro Kingdom Prime Minister Calvin Armstrong Rwomiire Akiiki, who described the monarch’s passing as an immense loss for the royal family, the kingdom, and the nation.

Born on 16 April 1992, King Oyo stepped into global prominence in September 1995 following the death of his father, King Patrick David Matthew Kaboyo Olimi III. At just three years old, he was crowned Omukama, earning a place in the Guinness World Records as the youngest reigning monarch on earth. During his early childhood, a council of regents guided the traditional administration until he took full direct leadership upon reaching adulthood in 2010.

Situated in the scenic landscape of western Uganda, Tooro is a traditional cultural kingdom with a history spanning over two centuries. While political governance rests with the central government, traditional institutions hold deep cultural significance, with the Omukama serving as the custodian of heritage for over two million Batooro people. Throughout his reign, King Oyo focused on youth leadership, vocational training, environmental sustainability, and healthcare initiatives, including partnering with international bodies to champion HIV/AIDS awareness across the region.
