World's youngest reigning traditional monarch dies aged 34

A traditional Ugandan ruler named as the world's youngest monarch has died aged 34, his prime minster announced.

Oyo Nyimba Kabamba Iguru Rukidi IV became king of Tooro in western Uganda at just three years old in 1995 after the death of his father.

The Toroo kingdom did not disclose the cause of King Oyo's death, but a Ugandan government minister was quoted in local media saying that he had been critically ill and was seeking treatment in the US.

Though Uganda is governed by an elected president, it has several traditional kingdoms which continue to have significant cultural influence despite not having political power.

Oyo, who Guinness World Records listed as the world's youngest reigning monarch , external , ruled over more than two million people. He was the 13th monarch of a kingdom that was founded in the early 19th Century.

Announcing his death, Tooro's Prime Minister Calvin Armstrong Rwomiire Akiiki called his passing on Thursday an "immeasurable loss" to the royal family and the people of Tooro.

"I call upon all the people of Tooro to remain united, calm and prayerful during this profoundly difficult time," Akiiki said on Friday. "May His Majesty the King rest in eternal peace."

The Tooro Kingdom follows a hereditary system in selecting its monarch.
