French Geodesic Mission
Edit

The French Geodesic Mission (also called the Geodesic Mission to Peru, Geodesic Mission to the Equator and the Spanish-French Geodesic Mission) was an 18th-century expedition to what is now Ecuador carried out for the purpose of measuring the roundness of the Earth and measuring the length of a degree of latitude at the Equator. The mission was one of the first geodesic (or geodetic) missions carried out under modern scientific principles, and the first major international scientific expedition.

  1. In the 18th century the nation of Ecuador did not yet exist. The area was under Spanish control and was called the Territory of Quito after the city of Quito. The fame brought to the region by the French Geodesic Mission influenced the adoption of the name Republic of Ecuador when the country gained independence in 1830. This national name also refers to the Earth's equator passing very close to the city of Quito, and which crosses the country from east to west. The first reference of the country on the equator was registered in Noticias Secretas de América, which referred to the lands of Ecuador as the jurisdiction of the Real Audiencia de Quito. Delegates from Guayaquil and Cuenca in the First Constituent Assembly suggested the name "Republic of Quito" which was initially scrapped, although the Spanish colony throughout the territory was known simply as Quito.
