Nicaragua is the largest country in the Central American isthmus, bordered by Honduras to the north and Costa Rica to the south. The country is situated between 11 and 14 degrees north of the Equator in the Northern Hemisphere, which places it entirely within the tropics. The Pacific Ocean lies to the west, and the Caribbean Sea to the east. The country's physical geography divides it into three major zones: Pacific lowlands; wet, cooler central highlands; and the Caribbean lowlands. On the Pacific side of the country are the two largest fresh water lakes in Central America—Lake Managua and Lake Nicaragua. Surrounding these lakes and extending to their northwest along the rift valley of the Gulf of Fonseca are fertile lowland plains, with soil highly enriched by ash from nearby volcanoes of the central highlands. Nicaragua's abundance of biologically significant and unique ecosystems contribute to Mesoamerica's designation as a biodiversity hotspot.
The Spanish Empire conquered the region in the 16th century. Nicaragua achieved its independence from Spain in 1821. Since its independence, Nicaragua has undergone periods of political unrest, dictatorship, and fiscal crisis—the most notable causes that led to the Nicaraguan Revolution of the 1960s and 1970s. Prior to the revolution, Nicaragua was one of Central America's wealthiest and most developed countries.

In 1990, Nicaragua elected Violeta Chamorro as its president, making it the first country in Central American history and the second in the Western Hemisphere to democratically elect a female head of state.
The population of Nicaragua, approximately 6 million, is multiethnic. Roughly a quarter of the population lives in the capital city, Managua; it is the
