The Nicaraguan government operates as a unitary presidential constitutional republic. The President of Nicaragua serves as both the head of state and government, overseeing the executive branch. The National Assembly, a unicameral legislature, is responsible for making laws and consists of 92 members elected for five-year terms. Nicaragua's political landscape has been shaped by various historical events, including the Sandinista Revolution in the late 1970s. The current president, Daniel Ortega, has been in power since 2007, leading a government that has faced criticism for its handling of political dissent and human rights issues.
