King Oyo Nyimba Kabamba Iguru Rukidi IV, the traditional ruler of Uganda’s Tooro Kingdom and once listed by Guinness World Records as the world’s youngest reigning monarch, has died aged 34. His death was announced by Tooro Prime Minister Calvin Armstrong Rwomiire Akiiki, who described it as an “immeasurable loss” and urged the kingdom’s people to remain united, calm and prayerful. The cause of death has not been disclosed. Ugandan media reported that King Oyo had been critically ill and was receiving treatment in the United States.
Oyo became king in 1995 at the age of three, following the death of his father. A regency, including his mother, Queen Mother Best Kemigisa, governed during his childhood. He was formally crowned in 2010, after turning 18. As the 13th monarch of the Tooro Kingdom, he was regarded as the leader of more than two million people. Although Uganda is governed by an elected president and parliament, its traditional kingdoms retain considerable cultural influence but no formal political authority.
King Oyo was known for supporting youth empowerment, education, climate conservation and HIV/Aids awareness. He also undertook humanitarian activities, including a visit to the United States as a child to support Aids orphans. His public profile included welcoming former Libyan leader Muammar Gaddafi to Tooro alongside President Yoweri Museveni.
Tooro officials said the succession was assured and that Oyo’s son, a prince whose identity will be announced later according to kingdom traditions, would be heir. Tributes came from Uganda’s Buganda and Rwenzururu kingdoms, the Federation of Uganda Football Associations, politicians and musicians. Football matches will observe a moment of silence through 4 September. Government minister Margaret Muhanga said the kingdom was in a sombre mood and announced plans to plant one million trees in Oyo’s memory.

Oyo Nyimba Kabamba Iguru Rukidi IV, the king of Uganda’s traditional Tooro Kingdom, died at age 34, according to Tooro regional leader and Prime Minister Calvin Armstrong Rwomiire Akiiki. No cause of death was immediately provided, although Ugandan media had previously reported that the king was seriously ill and receiving medical treatment in the United States. Officials said further details about funeral and mourning arrangements would be announced later and urged the people of Tooro to remain united, calm, and prayerful.
Oyo became king in 1995 at the age of three after the death of his father, Omukama Patrick David Matthew Kaboyo Olimi III. He was formally given full authority on his 18th birthday in 2010, at a ceremony attended by President Yoweri Museveni. His status as one of the world’s youngest monarchs attracted international attention, including visits from former Libyan leader Moammar Gadhafi. Guinness World Records said in 2025 that Oyo remained the youngest reigning monarch alive.
Although Uganda is a republic, it retains several traditional kingdoms that existed before colonial rule. Their political authority is largely symbolic, but they continue to exercise substantial cultural and social influence. Traditional monarchies were abolished after independence in 1962 and restored by Museveni in 1993.
Oyo studied in the United Kingdom and faced an unsuccessful challenge to his position in 2015 while he was abroad. He supported youth development, HIV prevention, environmental conservation, tourism, and climate-related causes. In 2022, he hiked in the Rwenzori Mountains to promote Ugandan tourism and highlight climate-change risks. His death prompted widespread national coverage and an outpouring of grief, while officials indicated that a previously undisclosed prince would inherit the crown.

Oyo Nyimba Kabamba Iguru Rukidi IV, the king of Uganda’s Tooro Kingdom, has died at age 34. Rukidi IV became the world’s youngest reigning monarch when he was crowned in September 1995 at just three years old, following the death of his father, Rukirabasaija Patrick David Matthew Kaboyo Olimi III, at age 49. He later entered the Guinness World Records for his historic accession.
Tooro Prime Minister Calvin Armstrong Rwomiire Akiiki announced that the king died at approximately 10 p.m. local time Thursday. In a statement, Akiiki described the death as an “immeasurable loss” for the royal family, the people of Tooro and Uganda, while urging the public to remain united, calm and prayerful. Officials said Rukidi IV died after an illness, but the kingdom did not disclose the specific cause of death. Akiiki reportedly said the king had been critically ill and receiving treatment in the United States.
Although Rukidi IV was unmarried, Ugandan government minister Balaam Barugahara said he had left an heir and that the continuity of the crown was assured. Rukidi IV was the 13th monarch of Tooro, a kingdom founded more than 200 years ago that ruled over more than two million people.
Uganda is formally a republic governed by an elected head of state, but it retains several traditional monarchies dating from the pre-colonial period. These kingdoms have little formal political authority, yet their monarchs continue to exercise considerable cultural and social influence. Rukidi IV’s death therefore represents both the loss of a young and internationally recognized monarch and a significant moment for Tooro’s traditional institution.
