Step-by-step explanation:
What did Bolívar do in Colombia?
Simón Bolívar, known as "The Liberator," played a crucial role in Latin America's quest for independence from Spanish rule. In Colombia, he orchestrated the liberation of New Granada (modern-day Colombia and Panama), leading an arduous campaign through the Andes and culminating in the decisive victory at the Battle of Boyacá in August 1819. This triumph was pivotal in the establishment of Gran Colombia, a federation which included present-day Colombia, Venezuela, Ecuador, and Panama. Bolívar spearheaded the creation of the Congress of Cúcuta, which adopted a central constitution and set forth progressive reforms, such as the gradual abolition of slavery and expansion of voting rights.
As the President of Gran Colombia from 1819 to 1830, Bolívar had a grand vision of a unified Latin America that resembled the federal union of the United States. He convened the Congress of the Americas in an effort to unite the Latin American nations but faced geopolitical challenges that eventually led to the dissolution of Gran Colombia. Bolívar's political and military actions in Colombia and the wider region laid the foundation for the current nation-states and sparked considerable social and political change.
