Throughout Africa’s modern political history, several sitting and former presidents have died under mysterious and controversial circumstances.
These deaths, often surrounded by secrecy, rumors, and speculation, have left many unanswered questions and fueled widespread theories ranging from political assassinations to foreign interference and internal power struggles.
In several cases, official explanations have been met with public scepticism, as the truth remains clouded by a lack of transparency or deliberate cover-ups.
Here are some of the African Heads of State who died under mysterious and unclear circumstances
Sylvanus Olympio
He was the first President of Togo, serving for about 993 days before he was assassinated during a military coup in 1963, under mysterious circumstances involving future dictator Eyadéma Gnassingbé.
During the coup, Olympio attempted to seek refuge at the U.S. Embassy in Lomé.
However, he was captured and shot dead near the embassy gates. Eyadéma later claimed responsibility for the killing.
Upon his assassination, the coup leaders installed Nicolas Grunitzky, a former political rival and Olympio’s brother-in-law, as the new president. Grunitzky’s government, however, was short-lived; in 1967,
Eyadéma led another coup, deposing Grunitzky and establishing a regime that he would lead until his death in 2005.
Thomas Sankara
He was the president of Burkina Faso, ruling for approximately 1,533 days before being assassinated in 1987 during a coup led by his former ally, Blaise Compaoré, with details of his death concealed for decades.
After his death, Blaise Compaoré immediately took power and ruled Burkina Faso for 27 years.
Sankara’s body was hastily buried in an unmarked grave, and his death was officially attributed to “natural causes” for decades.
Laurent-Désiré Kabila
The President of the Democratic Republic of Congo was in office for around 1,340 days before being shot dead by his bodyguard in 2001.

After the assassination, a military tribunal tried over 100 individuals, including Colonel Kapend and General Yav Nawej. Many were sentenced to death or long prison terms. However, the trial was widely criticized for its lack of transparency and due process.
In 2021, 23 of those convicted, including Kapend, were released after nearly two decades in prison.
Muammar Gaddafi
Muammar Gaddafi who ruled Libya for over 42 years (about 15,360 days), was captured and killed in 2011 during a NATO-supported rebellion, with the brutal manner of his death raising questions and controversy.
He was found hiding in a drainage pipe and captured by anti-Gaddafi fighters.
Videos later emerged showing him alive but bloodied and beaten. Shortly after, he was killed under unclear circumstances — likely executed without trial.
His death plunged Libya into ongoing chaos, with rival factions and militias vying for control.
The country has since experienced years of instability, civil conflict, and foreign interference.
Juvénal Habyarimana
The President of Rwanda served for roughly 7,573 days before dying in 1994 when his plane was shot down, an event that remains shrouded in mystery and directly triggered the Rwandan Genocide.
After his plane was shot down over Kigali, ignited the Rwandan Genocide. Hutu extremists, particularly the Interahamwe militia and elements of Habyarimana’s regime, used the event to launch a preplanned extermination campaign against Tutsis and moderate Hutus.
Roadblocks were set up within hours, and killings began in Kigali and spread nationwide.
Melchior Ndadaye
The first democratically elected President of Burundi was in office for only 103 days before he was assassinated by the military in 1993, under murky and politically charged circumstances.
Ndadaye’s assassination triggered widespread ethnic violence, sparking the Burundian Civil War (1993–2005).

Hutu militias and civilians retaliated against Tutsis, while the Tutsi-dominated army conducted reprisal killings. Over thousands of people were killed in the initial months of violence, with hundreds of thousands displaced.
Michael Sata
The President of Zambia served for about 1,131 days before dying in 2014 in a London hospital, with his deteriorating health concealed by officials, and the exact cause of death never fully clarified.
Guy Scott, who was Vice President at the time, became Acting President of Zambia.
This made Guy Scott the first white head of state in mainland sub-Saharan Africa since apartheid ended in South Africa.
However, due to constitutional restrictions (his parents were not Zambian by birth or descent), he was not eligible to run for the presidency in the upcoming election.
