Lake Managua in the context of "Momotombo"

Managua (Spanish pronunciation: [maˈnaɣwa]) is the capital and largest city of Nicaragua, and one of the largest cities in Central America. Located on the shores of Lake Managua, the city had an estimated population of 1,055,247 as of 2020, and a population of 1,401,687 in its metropolitan area. The city also serves as the seat of Managua Department.

Founded in 1819, Managua became the national capital in 1852. The city underwent a rapid expansion and urbanization between 1842 and 1930, leading it to become one of the most developed cities in Central America. Several earthquakes have affected the city's growth, especially the 1931 earthquake and the 1972 earthquake, but the city has been rebuilt several times. Today, the city is a major economic hub for both the country and Central America.

Lake Nicaragua or Cocibolca or Granada (Spanish: Lago de Nicaragua, Lago Cocibolca, Mar Dulce, Gran Lago, Gran Lago Dulce, or Lago de Granada) is a freshwater lake in Nicaragua. Of tectonic origin and with an area of 8,264 km (3,191 sq mi), it is the largest fresh water lake in Central America, the 19th largest lake in the world (by area) and the tenth largest in the Americas, slightly smaller than Lake Titicaca. With an elevation of 32.7 metres (107 ft) above sea level, the lake reaches a depth of 26 metres (85 ft). The intermittent Tipitapa River feeds Lake Nicaragua when Lake Managua has high water. Lake Cocibolca is between two other bodies of water, on top is Lake Xolotlán and below is the San Juan River. These body of waters complete the largest international drainage basin in Central America.

The lake drains via the San Juan River flowing east to the Caribbean Sea, historically making the city Granada on the northwest shore an Atlantic port, although Granada (as well as the entire lake) is closer to the Pacific Ocean geographically. The Pacific is near enough to be seen from the mountains of the largest island in the lake, Ometepe. The lake has a history of Caribbean pirates who assaulted Granada on three occasions. Before construction of the Panama Canal, a stagecoach line owned by Cornelius Vanderbilt's Accessory Transit Company connected the lake with the Pacific across the low hills of the narrow Isthmus of Rivas. Plans were made to take advantage of this route to build an Interoceanic Canal, the Nicaragua Canal, but the Panama Canal was built instead. In order to quell competition with the Panama Canal, the U.S. secured all rights to a canal along this route in the Bryan–Chamorro Treaty of 1916. However, since this treaty was mutually rescinded by the United States and Nicaragua in 1970, the idea of another canal in Nicaragua still periodically resurfaced, such as the Ecocanal proposal . In 2014, the government of Nicaragua offered a 50-year concession to the Hong Kong Nicaragua Canal Development Investment Company (HKND) to build a canal across Nicaragua at a cost of US$40 billion, with construction expected to begin in December 2014 and complete in 2019. Protests against the ecological and social effects of the canal as well as questions about financing led to doubts about the project, and in the end construction never began.

Managua (Spanish pronunciation: [maˈna.ɣwa]) is a department in Nicaragua. It covers an area of 3,465 km and has a population of 1,559,774 (2021 estimate), making it the country's most populated department. The capital is the city of Managua, which is also the capital of Nicaragua. The department has two coastlines, on the Pacific Ocean and on Lake Managua, but does not border Lake Nicaragua. The Nahua chiefdom of Tekwantepek was located in the Managua department. According to Spanish conquistador and historian Gonzalo Fernández de Oviedo y Valdés, Tekwantepek was one of the last chiefdoms in present-day Nicaragua to fall to the conquistadors and their central-Mexican allies. The chiefdom's name is a combination of the Nawat words tēkwani (jaguar), and tepek (hill), therefore the translation of Tekwantepek is "hill of jaguars" or "jaguar hill". The municipality of Ticuantepe located in the department is likely named after this chiefdom. The Indigenous inhabitants of Managua are the Chorotegas and Nahuas.
