West Africa Unites: ECOWAS Established in Lagos

Fifteen West African nations signed a treaty in Lagos and bet their collective future on economic integration. On May 28, 1975, the Treaty of Lagos established the Economic Community of West African States (ECOWAS), creating a regional bloc intended to promote trade, cooperation, and eventually a common market among nations that shared borders but often little else. The driving force was Nigerian Head of State Yakubu Gowon, who saw regional integration as both an economic necessity and a way to project Nigeria's leadership in West Africa. Togo's President Gnassingbe Eyadema co-sponsored the initiative. The 15 founding members spanned anglophone, francophone, and lusophone nations with vastly different colonial legacies, legal systems, and economic structures. The treaty established ambitious goals: elimination of customs duties between member states, a common external tariff, free movement of people, and harmonization of economic policies. A secretariat was established in Lagos, later moved to Abuja, to coordinate implementation. Progress on economic integration was slow. National interests, currency incompatibilities, and the dominance of informal cross-border trade complicated formal harmonization. Francophone members maintained parallel ties to France through the CFA franc zone, creating a bloc within a bloc. ECOWAS found its most consequential role not in economics but in security. Beginning with the Liberian civil war in 1989, the organization deployed ECOMOG peacekeeping forces to conflicts in Liberia, Sierra Leone, Guinea-Bissau, and Cote d'Ivoire. Nigerian-led military interventions, authorized under ECOWAS frameworks, became the primary mechanism for managing West African conflicts in the post-Cold War era. The community now encompasses 400 million people and accounts for the largest regional economy in sub-Saharan Africa. Free movement protocols allow ECOWAS citizens to travel across member states without visas, one of the few treaty provisions that functions as originally intended. Fifty years after Lagos, ECOWAS remains an imperfect but indispensable institution, holding together a region where borders drawn by European colonizers rarely correspond to economic or ethnic realities.
