Heads of state and government signed the Treaty of Lagos, creating the Economic Community of West African States (ECOWAS) to promote regional cooperation and economic integration across West Africa.
ECOWAS member states signed a Protocol on Non-Aggression, formalizing a commitment not to use force to settle disputes—an early building block for later ECOWAS security cooperation.
ECOWAS adopted the Protocol relating to Free Movement of Persons, Residence and Establishment, establishing a phased framework for visa-free entry, residency, and the right of establishment for ECOWAS citizens—central to the region’s integration agenda.
Member states signed the Protocol Relating to Mutual Assistance on Defence, deepening ECOWAS’s collective-security framework and explicitly referencing the earlier Non-Aggression Protocol.
ECOWAS’s Standing Mediation Committee decided to establish a Ceasefire Monitoring Group (ECOMOG) for Liberia, marking a major shift from primarily economic integration toward regional military intervention to manage civil conflict.
A major Human Rights Watch report evaluated ECOMOG’s Liberia intervention, crediting it with halting some violence while also documenting serious human rights concerns—illustrating the tensions between stabilization and civilian protection in ECOWAS operations.
ECOWAS members signed a revised treaty in Cotonou, updating the organization’s legal foundations and expanding its mandate, including stronger provisions for political cooperation and regional peace and security.
After Sierra Leone’s May 1997 coup, ECOMOG forces backed efforts that culminated in the removal of the AFRC junta and restoration of President Ahmad Tejan Kabbah in early 1998, reinforcing ECOWAS’s emerging anti-coup norm in practice.
ECOWAS prepared to complete ECOMOG’s interposition deployment in Guinea-Bissau pursuant to the Abuja peace process, reflecting ECOWAS’s continued reliance on regional forces to separate belligerents and support political settlements.
Member states signed the Protocol Relating to the Mechanism for Conflict Prevention, Management, Resolution, Peacekeeping and Security—an institutional framework that codified ECOWAS tools for mediation, peace support operations, and regional security cooperation.
ECOWAS adopted the Supplementary Protocol on Democracy and Good Governance, strengthening regional standards on constitutional rule, elections, and governance and providing a normative basis for later political responses to unconstitutional changes of government.
ECOWAS began deploying its peace force to Côte d’Ivoire amid the country’s civil war, an intervention later reinforced by UN Security Council authorizations—showing ECOWAS’s growing role as a first responder in regional crises.
ECOWAS deployed the ECOWAS Mission in Liberia (ECOMIL) as the Second Liberian Civil War ended, providing an immediate stabilization presence ahead of a UN takeover—an example of ECOWAS bridging operations into UN peacekeeping.
ECOWAS conducted a regional military intervention (ECOMIG) to support the enforcement of election results and a peaceful transfer of power in The Gambia, representing a mature application of ECOWAS’s post-2001 governance and security norms.
