  5. 1776
    Atlantic Slave Trade

    Peak of the slave trade

    Ouidah ships up to 20,000 captives per year — the most active port in the Atlantic slave trade during this period. Dahomean revenues enable the maintenance of a major army and the financing of administrative complexes. This economic concentration reinforces royal absolutism.

  6. 1804
    Kingdoms & Empires

    Reign of Ghezo

    Ghezo profoundly reforms Dahomey: military restructuring, formalization of the Agojie (warriors of earlier origins), and adaptation to growing European pressures. He adopts abolitionist rhetoric while maintaining alternative forms of slavery, marking a major strategic shift. Ouidah prospers under his reign despite commercial tensions.

    Atlantic Slave Trade

    Abolition of the slave trade

    Official Anglo-Dahomean treaty banning the slave trade. Ouidah begins its economic transition toward other products (palm oil, coconut, cocoa). Clandestine trading persists for two decades before gradually disappearing around 1870.

  8. 1890-1894
    Colonial Period

    Behanzin's Resistance and Colonial Campaign

Ouidah becomes the scene of intense battles between the Dahomean army and better-armed colonial troops. Behanzin's capture in 1894 marks the end of Dahomean political autonomy and the systematic looting of royal treasures repatriated to France.

The artifacts return to Ouidah, closing a historical loop of plunder and reclamation.
