Dates of independence

By the end of the eighteenth century, Spanish and Portuguese power waned as other European powers took their place, notably Britain and France. Resentment grew over the restrictions imposed by the Spanish government, as well as the dominance of native Spaniards (Iberian-born peninsulares) over the major institutions and the majority population, including the colonial-born Spaniards (criollos, Creoles). Napoleon's invasion of Spain in 1808 marked the turning point, compelling Creole elites to form juntas that advocated independence. Also, the newly independent Haiti, the second oldest nation in the New World after the United States and the oldest independent nation in Latin America, further fueled the independence movement by inspiring the leaders of the movement, such as Simón Bolívar and José de San Martin, and by providing them with considerable munitions and troops.
