Which two regions combined to form Gran Colombia?

Gran Colombia was formed by the combination of regions that were previously under Spanish colonial rule, specifically the Viceroyalty of New Granada and the Viceroyalty of Peru. The Viceroyalty of New Granada included territories that would later become present-day Colombia, Ecuador, Panama, and Venezuela, while the Viceroyalty of Peru encompassed a larger area that included much of South America.

The establishment of Gran Colombia in 1819 was a significant moment in Latin American history as it united these regions under a single republic after they gained independence from Spanish colonial rule. This union aimed to foster political stability and economic integration among the newly independent countries. The choice reflects an understanding of the historical context and the regions that actually participated in the formation of Gran Colombia during the early 19th century.
