In barely ten months, what had been hailed as Cameroon's smoothest presidential transition turned into an open rupture. On November 4, 1982, Ahmadou Ahidjo, in power since independence, handed the presidency to his prime minister, Paul Biya. Less than a year later, the two men were publicly attacking each other from opposite camps.
The breaking point came in March 1983: Ahidjo, who had remained head of the single party, the Cameroon National Union (UNC), pushed to entrench his influence over the state apparatus. Biya responded by removing several of his predecessor's allies from government. Isolated, Ahidjo left Cameroon in July 1983 to settle in France.
On August 22, 1983, Biya announced on the radio the discovery of a plot against state security. Five days later, on August 27, Ahidjo in turn resigned as head of the UNC and, from exile, publicly denounced a "police state of terror" set up by his successor — a definitive rupture between the two men who, a year earlier, had jointly organized the handover of power.
The affair ended up before a military court: the trial opened in Yaoundé on February 23, 1984, with two of Ahidjo's associates pleading guilty to plotting his assassination. On February 28, the military tribunal sentenced Ahmadou Ahidjo to death in absentia. Paul Biya commuted the sentence to detention on March 14, 1984 — the sentence was therefore never carried out.
Historians of the period see this episode as the abrupt end of a transition once presented as a model of African continuity. Above all, it exposed the fragility of a power inherited rather than won, and how quickly Biya locked down the single party's levers of control after taking office.
Ahidjo died in exile in Dakar in 1989, never having returned to Cameroon. More than four decades on, his official rehabilitation remains politically sensitive — the question of repatriating his remains still resurfaces regularly in Cameroonian public debate.
