Nicaragua is a unitary republic, divided for administrative purposes into fifteen departments (departamentos) and two autonomous regions (regiónes autónomas):
In 1987, the new constitution established the Charter of Autonomy (limited self-government) for the former department of Zelaya, comprising the entire eastern half of the country. The department was divided into two autonomous regions (communities). The Charter of Autonomy is largely based on the model used by Spain. The communities are governed by a Governor and a Regional Council.
