Which country was created in 1819 that encompasses the actual modern-day countries of Panama, Venezuela, Colombia, and Ecuador?

Greater Columbia (Gran Colombia in Spanish) is a name used today for the state that encompassed much of northern South America and part of southern Central America from 1819 to 1831. It included the territories of present-day Colombia, Venezuela, Ecuador, Panama, northern Peru, western Guyana and northwest Brazil.

The country was created in 1819 by the Congress of Angostura and ratified by the counterparts in the city of Cucuta in 1821. The new country was supposed to be the union of Venezuela and New Granada into one country called the Republic of Columbia.

Panama and Ecuador joined in 1821 and 1822 respectively.

Note: The term "Gran Colombia" is used in history to distinguish this larger country from the present-day Republic of Colombia.

Since Gran Colombia's territory corresponded more or less to the original jurisdiction of the former Viceroyalty of New Granada, it also claimed the Caribbean coast of Nicaragua also known as the "Mosquito Coast"
