Fort Portal, Uganda — The Tooro Kingdom is in mourning following the unexpected passing of its king, Oyo Nyimba Kabamba Iguru Rukidi IV, who died at the age of 34. His death occurred on August 27, 2026, while he was receiving medical treatment in the United States. The royal family and the kingdom are navigating the deep sorrow of losing a monarch celebrated for his vibrant leadership and potential in fostering unity among the Batooro people.
As the news of his death spread, tributes poured in from around the globe, with the kingdom’s official memorial page receiving 191 messages of condolence and candles lit in memory of the king from 375 individuals representing 26 nations. Notably, the largest number of condolences came from Uganda, with 126 messages, reinforcing the profound impact he had on his homeland. The kingdom has established a physical Book of Condolences at Buziga Palace to allow the public to express their grief.
Tooro Kingdom Prime Minister Calvin Armstrong Rwomiire Akiiki addressed the nation in a statement, urging the Batooro to maintain unity, composure, and faith during this challenging time. He reflected on the significance of the loss for both the royal family and the entire nation of Uganda, emphasizing the king’s critical role in the community.
President Yoweri Kaguta Museveni later provided further details about the king’s health struggles, revealing that he had been battling aggressive cancer. The diagnosis was conveyed to him by Queen Mother Best Kemigisa, and the government facilitated the king’s travel for treatment in Germany before he ultimately passed away in the U.S. Museveni expressed his condolences and lamented the tragic fate of a monarch who experienced the loss of his own parents as a child, passing away at a young age himself.
Oyo’s journey to the throne was extraordinary; he was crowned at the tender age of three in September 1995, recognized by Guinness World Records as the youngest reigning monarch globally. Although a regency managed the kingdom’s duties during his childhood, he took on full rulership after turning 18 in 2010. His reign spanned nearly 31 years, marking him as the 13th king of Tooro, a kingdom with roots dating back to the early 19th century.
As Uganda mourns, various leaders and communities across the nation have expressed their grief. The Buganda Kingdom, among the largest and most influential traditional institutions, extended its condolences to the Tooro Kingdom. Meanwhile, the Federation of Uganda Football Associations observed a moment of silence before matches through early September as a tribute to the late king.
In recognition of his legacy, initiatives are being launched in his memory, including plans to plant one million trees. This effort was announced by Margaret Muhanga, a member of parliament and minister, who highlighted the solemn atmosphere throughout Tooro, where residents are grieving collectively. Many Ugandan artists and public figures, including musician Juliana Kanyomozi, shared their sorrow on social media, underscoring the profound impact of his death on both cultural and social spheres.
The succession plan for the Tooro Kingdom will be guided by tradition. Akiiki confirmed that an heir has been identified, although the identity of the new potential king is to be disclosed later. This process will be managed by a committee of Babiito elders and is designed to maintain the continuity of monarchy in Tooro following the passing of King Oyo.
President Museveni has mandated an official burial for the late king, ordering that flags fly at half-mast for three days. The national mourning period will commence once the king’s body arrives at Karuziika Palace, and no specific burial date has yet been announced. While arrangements are being finalized, the kingdom’s official channels will keep the public updated about the plans for the coming days.
