In 1954, Suriname became one of the constituent countries of the Kingdom of the Netherlands, along with the Netherlands Antilles and the Netherlands. In this construction, the Netherlands retained control of its defense and foreign affairs. In 1974, the local government, led by the National Party of Suriname (NPS) (whose membership was largely Creole, meaning ethnically African or mixed African-European) started negotiations with the Dutch government leading towards full independence, which was granted on 25 November 1975. A large part of Suriname's economy for the first decade following independence was fueled by foreign aid provided by the Dutch government.
