Nicaragua, officially the Republic of Nicaragua, is the largest country in the Central American isthmus, bordering 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.
Nicaragua's tropical east coast is very different from the rest of the country. The climate is predominantly tropical, with high temperature and high humidity. Around the area's principal city of Bluefields, English is widely spoken along with the official Spanish. The population more closely resembles that found in many typical Caribbean ports than the rest of Nicaragua.

Geophysically, Nicaragua is surrounded by the Caribbean Plate, an oceanic tectonic plate underlying Central America and the Cocos Plate. Since Central America is a major subduction zone, Nicaragua hosts most of the Central American Volcanic Arc. Nicaragua has three distinct geographical regions: the Pacific lowlands, fertile valleys which the Spanish colonists settled, the Amerrisque Mountain, and the Mosquito Coast. The low plains of the Atlantic Coast are 60 mi wide in areas. They have long been exploited for their natural resources.
The main language is Spanish, although native tribes on the eastern coast speak their native languages, such as Miskito, Sumo, and Rama, as well as English Creole. The mixture of cultural traditions has generated substantial diversity in art and literature, particularly the latter given the various literary contributions of Nicaraguan poets and writers, including Rubén Darío, Pablo Antonio Cuadra and Ernesto Cardenal.

Religion is a significant part of the culture of Nicaragua and is referred to in the constitution. Religious freedom, which has been guaranteed since 1939, and religious tolerance are promoted by both the Nicaraguan government and the constitution. Nicaragua has no official religion. Catholic Bishops are expected to lend their authority to important state occasions, and their pronouncements on national issues are closely followed. They can also be called upon to mediate between contending parties at moments of political crisis.
