King Oyo Nyimba Kabamba Iguru Rukidi IV, the traditional ruler of Uganda’s Tooro Kingdom and once recognised as the world’s youngest reigning monarch, has died at the age of 34.
The monarch’s death was announced on Thursday by the Prime Minister of Tooro Kingdom, Calvin Armstrong Rwomiire Akiiki, who described it as a major loss to the royal family and the people of Tooro.
The cause of death was not immediately disclosed. However, local media reports quoted a Ugandan government minister as saying the king had been critically ill and was receiving medical treatment in the United States.
King Oyo ascended the throne in 1995 at the age of three following the death of his father. A regency was established to oversee the kingdom until he reached adulthood.
He was formally crowned in 2010 at the age of 18.
Although Uganda operates under an elected government headed by a president and parliament, the country retains several traditional kingdoms that continue to play important cultural and social roles despite having no formal political authority.
The Tooro Kingdom, which was established in the early 19th Century, has more than two million people under its traditional jurisdiction. Oyo was its 13th monarch.
Guinness World Records recognised him as the world’s youngest reigning monarch after he took the throne at the age of three.
During his reign, King Oyo was associated with initiatives focused on youth empowerment, education, environmental conservation and HIV/AIDS awareness.
He also represented the kingdom on international visits. At the age of 10, he travelled to the United States with his mother, Queen Mother Best Kemigisa, on a humanitarian mission involving AIDS orphans in Uganda.
Following the announcement of his death, other Ugandan traditional institutions, including the Buganda Kingdom and Rwenzururu Kingdom, expressed condolences to the people of Tooro.
The Federation of Uganda Football Associations also paid tribute to the late monarch, describing him as a supporter of the sport and announcing a moment of silence before matches until September 4 in his memory.
Tooro Prime Minister Akiiki called on residents to remain united, calm and prayerful during the mourning period.
Although King Oyo was not officially married, the Tooro Kingdom said the succession of the crown would continue. Akiiki said the late monarch left behind a prince who will serve as heir, with his identity expected to be formally announced in accordance with the kingdom’s traditions and customs.
