Commander Mathieu Kérékou and the armed forces overthrow the government of the Republic of Dahomey, suspend the constitution, and dissolve existing national institutions—setting the stage for the later socialist state.
Kérékou publicly announces the state’s adoption of Marxism–Leninism, marking the ideological turn that would define the regime and underpin creation of a party-state structure.
The country is renamed from the Republic of Dahomey to the People’s Republic of Benin, formalizing the revolutionary state project that would last until 1990.
Mathieu Kérékou founds the People’s Revolutionary Party of Benin (PRPB); under the new constitutional order it becomes the sole legal party, institutionalizing one-party rule.
A French-led mercenary force attempts to overthrow Kérékou’s government in Cotonou in the event often known as Opération Crevette (“Operation Shrimp”); the attempt fails.
In response to the January 1977 attack, the UN Security Council adopts Resolution 404 and establishes a special mission to investigate the events against Benin.
UN Security Council Resolution 405 strongly condemns the mercenary attack and urges assistance to repair damage, reinforcing international opposition to destabilization by hired forces.
Voters are asked to approve or reject a single PRPB list for the National Revolutionary Assembly; afterwards, the Assembly elects Kérékou president unopposed (6 Feb 1980).
Another single-list PRPB election is held for the National Revolutionary Assembly; Kérékou is again elected president unopposed by the Assembly (31 Jul 1984).
The PRPB remains the sole legal party as another approval-style legislative election is held; Kérékou is re-elected president by the Assembly on 2 Aug 1989.
Facing deep economic and social crisis, the ruling PRPB announces it will abandon Marxism–Leninism and promises constitutional and political reforms, accelerating the move away from the socialist one-party state.
The National Conference of Active (Vital) Forces of the Nation meets in Cotonou, providing a negotiated framework for political liberalization and a transition toward multiparty democracy.
The state drops the “People’s” designation and becomes the Republic of Benin, symbolizing the formal end of the People’s Republic era in the transition away from Marxist-Leninist one-party rule.
As part of the transition prompted by the National Conference, Nicéphore Dieudonné Soglo assumes the post of Prime Minister, tasked with steering reforms toward constitutional and electoral change.
The People’s Revolutionary Party of Benin (PRPB), which had served as the sole legal party during the People’s Republic period, is dissolved as the transition to pluralist politics proceeds.
Voters approve a new constitution by referendum, endorsing a multiparty political system and providing the legal framework for subsequent competitive elections.
