Final answer:
Simón Bolívar's actions led to the creation of the independent countries of Colombia, Venezuela, and Ecuador following the dissolution of Gran Colombia.
Step-by-step explanation:
One long-term impact of Bolívar's actions was to create the independent countries of Colombia, Venezuela, and Ecuador. Simón Bolívar, known as 'The Liberator', played a crucial role in the Latin American wars of independence from the Spanish Crown.
His military campaigns were instrumental in liberating the territories of Gran Colombia, an area encompassing modern-day Venezuela, Colombia, and Ecuador. The victory at Boyacá in 1819 was decisive, and thereafter, the formation of Gran Colombia was realized under his leadership.
However, this federative nation eventually dissolved, leading to the independence of the countries we know today as Colombia, Venezuela, and Ecuador.
