ACP–EU development cooperation
Development cooperation between the European Union (EU) and the countries of the African, Caribbean and Pacific Group of States (ACP) started in 1957 with the Treaty of Rome, which first established a collective European development policy. The Treaty of Rome granted associated status to 31 overseas collectivities and territories (OCTs) and provided for the creation of a European Development Fund (EDF) intended to grant technical and financial assistance to the countries which were still under European rule at the time.
