Uganda’s King Oyo Nyimba, who ascended the throne at just three years old and spent nearly three decades as the cultural leader of Tooro Kingdom, has died aged 34.

The monarch died at around 10pm local time on Thursday, according to the prime minister of the Tooro Kingdom, Calvin Armstrong Rwomiire Akiiki.

The cause of death was not immediately disclosed.

Earlier, Ugandan State Minister for Youth and Children Affairs Balaam Barugahara said the king was receiving medical treatment in the United States.

Oyo Nyimba became king following the death of his father, Rukirabasaija Patrick David Matthew Kaboyo Olimi III.

He was formally crowned on September 12, 1995, becoming one of the world’s youngest monarchs and beginning a reign that lasted almost three decades.

The king ruled over Tooro Kingdom in western Uganda, near the border with the Democratic Republic of Congo.

Although Uganda is governed as a republic under an elected president, the country retains several traditional kingdoms whose roles are largely cultural and symbolic.

Their monarchs continue to play important roles in preserving cultural heritage, traditions and community identity.

Announcing Oyo Nyimba’s death in a post on X, Akiiki expressed deep sorrow over the loss of the monarch.

Tributes have since poured in from political figures, cultural leaders and members of the public across Uganda.

Opposition leader and musician Bobi Wine described the king’s death as devastating and offered prayers for his soul in a message shared on X.

Akiiki also said the late monarch had left an heir, assuring the people of Tooro that the royal succession would continue.

In a message marking Oyo Nyimba’s birthday in April, Akiiki described him as a young monarch closely connected to the realities of his people, saying his youth brought energy and a fresh perspective to the kingdom.

King Oyo Nyimba’s death brings to an end a nearly three-decade reign during which he served as the cultural figurehead of Tooro Kingdom for most of his life. (Arise News)
