President Yoweri Kaguta Museveni has mourned the death of Tooro Kingdom’s King Oyo Nyimba Kabamba Iguru Rukidi IV, who died at the age of 34, and directed that the late monarch be accorded an official burial.

In a condolence message, Museveni described the death of King Oyo as a major loss to Tooro and Uganda, recalling that the monarch had shown potential to work with both the Central and Local Governments in efforts to develop the kingdom.

King Oyo died on Thursday, August 27, 2026, after receiving medical treatment in the United States. His death was announced by Tooro Kingdom officials, prompting widespread mourning across Uganda.

In his message, President Museveni said Queen Mother Best Kemigisa had informed him several months earlier that King Oyo was suffering from an aggressive form of cancer.

According to Museveni, the government supported the royal family in seeking medical treatment for the King, first in Germany and later in the United States, where he died.

The President's account provides additional information about the circumstances surrounding the monarch's death. Earlier reports had said the specific cause of death had not been publicly disclosed, making it appropriate to attribute the cancer information directly to Museveni.

Museveni also revealed that King Oyo left behind a young boy who is expected to become the heir to the Tooro throne.

The President said Queen Mother Kemigisa informed him about the heir during a telephone conversation and that the child would be introduced to the public at an appropriate time.

The announcement comes as Tooro Kingdom mourns the late monarch and is preparing for the next stage in the succession of the traditional institution. Reports from the kingdom have also assured the public of continuity following Oyo's death.

King Oyo was born on April 16, 1992, to the late King Patrick David Matthew Kaboyo Olimi III and Queen Mother Best Kemigisa.

He became Omukama of Tooro in September 1995 following the death of his father. At only three years old, Oyo became the world's youngest reigning monarch, a distinction later recorded by Guinness World Records.

Because of his young age, members of the royal family and other regents played important roles in guiding the kingdom during his childhood. Oyo later assumed greater responsibilities as he grew into adulthood.

His reign made him one of Uganda's best-known traditional leaders, attracting international attention because of his unusually young accession to the throne.

Although Uganda is a republic headed by an elected president, traditional kingdoms continue to play an important cultural and social role.

The Tooro Kingdom is one of Uganda's traditional institutions and serves as an important symbol of Batooro heritage and identity. King Oyo's role was primarily cultural rather than political, and his public activities included initiatives involving young people and wider social issues.

King Oyo also served as a regional champion for HIV and AIDS awareness among young people. UNAIDS identified him as a Champion for HIV and AIDS among Young People in Eastern and Southern Africa in 2016.

In his condolence message, Museveni praised King Oyo for maintaining a working relationship with the Central Government.

The President said the late monarch had avoided using the cultural institution to promote sectarianism and urged other cultural leaders to understand the importance of maintaining a constructive relationship with government.

Museveni's remarks reflect the political and cultural sensitivity surrounding Uganda's traditional institutions, which were restored in the 1990s but do not exercise political authority under Uganda's constitutional system.

As part of the official mourning arrangements, President Museveni directed that King Oyo be given an official burial.

He further ordered that flags be flown at half-mast for three days: the day before the burial, the day of the burial and the day after.

The directive is intended to honour the late Tooro monarch and mark his death as a significant national loss.

King Oyo's death has triggered an outpouring of condolences from across Uganda and beyond.

For more than three decades, his name had been closely associated with Tooro Kingdom after he ascended the throne as a three-year-old child. His death at 34 brings an end to a remarkable reign that began in childhood and continued into adulthood.

As preparations for his official burial get underway, attention will also turn to the future of the Tooro monarchy and the young heir whose identity, according to President Museveni, will be made public at the appropriate time.

President Museveni concluded his message by extending condolences to the Tooro Royal Family and the people of Uganda and praying for the late King's soul to rest in eternal peace.
