Oyo Nyimba Kabamba Iguru Rukidi IV, the Omukama, or king, of Uganda’s Tooro Kingdom, was 34 when a hospital in Dallas became the place of his death at about 10 p.m. Ugandan time on Thursday, August 27, 2026. A monarch who entered the record books as a toddler, he has since drawn mourners in 24 countries to sign an online book of condolence. He will be buried on Saturday, September 12 — the 31st anniversary of his coronation.
The kingdom’s official memorial page showed 408 published messages of condolence as of September 9. Mourners have also lit 756 candles in the king’s memory, and the page counts 39 countries represented — Uganda, the United States, the United Kingdom, Brazil, the Democratic Republic of the Congo, Belgium and Kenya among them — with those counters live and still rising. A single mourning motto has gathered the grief — “Omukama Atulize. Enkuba Etutire.” A physical Book of Condolences was opened at Buziga Palace on August 28. In a new official communication dated September 7 and headed “Condolence Contributions for the Late King Oyo,” the kingdom said Tooro Kingdom “continues to mourn the passing of our beloved King.”
Tooro Kingdom Prime Minister Calvin Armstrong Rwomiire Akiiki announced the death in a statement issued August 27, urging the Batooro to remain united, calm and prayerful. “This is an immeasurable loss to the Royal Family, the people of Tooro and the nation of Uganda,” Akiiki said in the statement. No cause of death appeared in that first announcement, which said only that the monarch had been critically ill and receiving treatment in the United States.
Museveni Reveals Cancer Battle
The details came later from Ugandan President Yoweri Kaguta Museveni, who said in a statement on his official X account that the king had died of an aggressive cancer while under medical care in the United States. Queen Mother Best Kemigisa, known as Nyinomukama, had come months earlier to tell him of the diagnosis, the president said. The family travelled to Germany for treatment and then to the United States, where the king died, with the government supporting the trips.
The president, writing on behalf of himself, First Lady Janet Kainembabazi Museveni and all Ugandans, extended condolences to the royal family. He lamented that a monarch orphaned as a small boy had himself died young. “How unfair life can be!!” Museveni wrote. King Oyo, he added, had shown the potential to work with central and local government to develop Tooro.
A King Crowned at Three
The boy who would become a global curiosity was born April 16, 1992. His father, Rukirabasaija Patrick David Matthew Kaboyo Olimi III, died at 49, and the son was crowned on September 12, 1995. He was three years old when he took the throne of the kingdom in western Uganda, and Guinness World Records recognized him as the world’s youngest reigning monarch.
Through his childhood, a regency that included the queen mother ran the kingdom’s traditional affairs. His official coronation followed on April 17, 2010, the day after his 18th birthday, and he took full direct leadership on reaching adulthood, a reign that lasted nearly 31 years in all. From the royal seat at Karuziika Hill in Fort Portal, the 13th monarch of Tooro — a kingdom established in the early 19th century — served as custodian of the heritage of more than two million Batooro.
An elected president and parliament govern Uganda, a republic, yet several traditional monarchies also sit within its borders, exercising political power that is largely symbolic while their cultural and social sway stays considerable. King Oyo turned that space into a public profile built on education and vocational training, youth empowerment, healthcare and HIV/AIDS awareness, and environmental and climate conservation.
A Nation and a Continent Mourn
Mourning alongside the people of Tooro was Buganda Kingdom, the country’s largest and most influential traditional institution, while Rwenzururu Kingdom also sent condolences to all those grieving the loss. A genuine ally of the game was how the Federation of Uganda Football Associations saluted the late monarch, and it ordered a moment of silence before kickoff at every match through September 4.
Nobody was smiling, said Margaret Muhanga, the member of parliament for Fort Portal North Division, who described the mood across the kingdom as somber and said one million trees would be planted in the king’s honor during the mourning period. Tributes also came from Ugandan musician Juliana Kanyomozi, who called it a dark day for Tooro in an Instagram post, and from pop star-turned-politician Bobi Wine. Organizers of the Tooro Annual Youth Conference 2026 postponed the event, saying they were joining the people of Tooro in mourning.
Princess Elizabeth Bagaya, 90, the king’s paternal aunt and a former regent, mourned him after the body arrived on a chartered flight from Nairobi. “He had just started and loved Batooro so much,” she said. She added: “God should have protected this child who was still young and instead taken us who are old.”
At Karuzika Royal Palace in Fort Portal, a heavy downpour sent mourners scrambling for shelter during the mourning period. Tooro tradition regards rain at a royal gathering as a blessing.
Succession and an Official Burial
Tooro selects its monarch through a hereditary system, and the kingdom says the line is intact even though King Oyo was unmarried. A prince survives the king as his heir, Akiiki said, and that heir’s identity will be formally revealed at the appropriate time, in keeping with the traditions and customs of Tooro. The prime minister said the continuity of the crown is assured. Speaking before the death was confirmed, Local Government Minister Balaam Barugahara had said only that the king remained critically ill and under medical management in the United States.
Identifying the successor and announcing him fell to a 21-member committee of Babiito elders, headed by the Omujwera Musuuga, Charles Kamurasi. A young boy heir would be introduced to the public at the right moment, the queen mother told the president by telephone, he said. A name has now come from the committee: George Desmond Kamurasi, a British citizen who captains and keeps goal for ninth-tier English club SE Dons in London, was chosen as the late king’s successor on the Friday before September 8, with 15 of 18 members voting for him, according to Ugandan reports. His father was the second son of King George Rukidi III, making him King Oyo’s cousin, and he has a wife and son. Local press reports say Kamurasi is reportedly reluctant to leave London and take up the role. He has offered no public comment, and a match clashing with the funeral awaits his Bexleyheath-based team.
An official burial for the king has been directed by Museveni, with flags flying at half-mast on the day before the burial, the burial itself and the day after — September 11, 12 and 13. Repatriation of the remains on September 4 opened the nine-day official mourning period.
The remains reached Entebbe International Airport at 10 a.m. on Friday, September 4, a day later than first planned, after a flight from Texas by way of Amsterdam and Nairobi. Museveni received them in person. A military helicopter carried the casket to Kyegegwa, where an open carriage took it more than 100 kilometers through Kyegegwa, Kyenjojo and Kabarole districts, moving slowly so mourners could line the route before it reached Karuziika Palace that evening. The king has lain in state there since, the casket visible but the body concealed in keeping with royal custom, with evening prayers each day and restrictions on farming, entertainment and loud music across the kingdom.
The burial falls on Saturday, September 12, the ninth day and, by the kingdom’s reckoning, the 31st anniversary of the coronation. Mourners are to be seated by 8 a.m., ahead of a service at St John’s Cathedral from 9 a.m. to noon. A procession to the Karambi Royal Tombs follows, with burial rituals and a military gun salute between 1 and 2 p.m.
