	From the 17th to 19th century the main political entity in the area of central present-day Benin was the Kingdom of Dahomey, a military power in the region and an active participant in the trans-Atlantic slave trade. This contact with the New World has made a lasting contribution to Benin’s culture. The Kingdom of Dahomey, and the city-state of Porto-Novo on the coast, were incorporated in the colony of French Dahomey in 1894. Independence from France was won as the country of Dahomey in 1960, after which was a period of civil and military unrest, culminating in the proclamation of a Marxist-Leninist state in 1975, when the country was renamed the People’s Republic of Benin. A change to multi-party democratic political system in 1991 saw the country officially renamed the Republic of Benin.
