Final answer:
One significant long-term effect of Simón Bolívar's actions was the spread of republican ideals and a strong central government in newly independent Latin American nations, as well as the initiation of policies leading to the gradual abolition of slavery in the region.
Step-by-step explanation:
Bolívar was instrumental in liberating territories that formed Gran Colombia ( Venezuela, Colombia, Ecuador ), and he emphasized the need for a strong central government to maintain order and unity in the newly independent nations.
One long-term impact of Simón Bolívar's actions was the establishment and promotion of republican ideals in Latin American countries following their independence from Spanish rule.
This centralist approach contrasted with the federalist systems adopted in other regions, influencing Latin America's political landscape long after Bolívar's death. Furthermore, his strategy of offering freedom to enslaved individuals in exchange for military support paved the way for the gradual abolition of slavery in these nations, a policy established by the Congress of Cúcuta as part of Gran Colombia's constitution.
