King Oyo ascended to the throne at the age of three but was crowned on reaching adulthood at 18 in 2010
Uganda’s King Oyo Nyimba Kabamba Iguru Rukidi IV, who was recognised as the world’s youngest reigning monarch, has died at the age of 34, according to the Prime Minister of the Tooro Kingdom.
King Oyo ascended the throne of Tooro in western Uganda in 1995 at just three years old, following the death of his father.
The Tooro Kingdom has not disclosed the cause of his death. However, local media quoted a Ugandan government minister as saying the monarch had been seriously ill and had travelled to the United States for medical treatment.
Although Uganda is governed by an elected president and parliament, the country maintains several traditional kingdoms that retain considerable cultural and historical influence despite having no formal political authority.
King Oyo ruled over a population of more than two million people and was the 13th monarch of the Tooro Kingdom, which dates back to the early 19th century. Guinness World Records recognised him as the youngest reigning monarch in the world when he assumed the throne.
Announcing his death on Friday, Tooro Prime Minister Calvin Armstrong Rwomiire Akiiki described the monarch’s passing on Thursday as an “immeasurable loss” to the royal family and the people of Tooro.
He urged residents of the kingdom to remain united, calm and prayerful during the mourning period and prayed for the late king’s eternal rest.
The Tooro Kingdom uses a hereditary system to determine succession.
Although King Oyo was not formally married, the Prime Minister said the royal succession would continue, noting that the late monarch had left behind a son who would inherit the throne.
According to Akiiki, the identity of the prince would be announced at the appropriate time in line with Tooro traditions and customs.
When Oyo became king at the age of three, a regency was established, including his mother, to oversee the kingdom until he reached adulthood. He was formally crowned at 18.
King Oyo was widely respected and was known for supporting initiatives focused on youth empowerment, education, environmental conservation and HIV/AIDS awareness.
Uganda’s Buganda Kingdom, the country’s largest and most influential traditional institution, expressed its condolences to the people of Tooro and described King Oyo as an important figure in Uganda.
The Rwenzururu Kingdom also conveyed its sympathies to the Tooro royal family and everyone mourning the monarch.
Tributes have also come from across Uganda.
The Federation of Uganda Football Associations described King Oyo as a “true friend of the beautiful game” and announced that all football matches would observe a minute of silence before kick-off until September 4 to honour his legacy and contribution to the sport.
Government minister Margaret Muhanga described the atmosphere in Tooro as sombre, saying the king’s death had left residents deeply saddened.
She said King Oyo had died while still in the prime of his life but had made a significant impact on his kingdom despite his relatively young age.
Muhanga also announced plans to plant one million trees in the late king’s honour during the mourning period and encouraged neighbouring districts in Tooro to participate.
Ugandan musician Juliana Kanyomozi described the monarch’s death as a “very dark day for Tooro”, while musician-turned-politician Bobi Wine also paid tribute and prayed for King Oyo’s soul to rest in eternal peace.
