Explanation:

The Hispano-American independence wars or Hispano-American independence wars were a series of armed conflicts that developed in the American possessions of the Spanish Empire in the early nineteenth-century, in which they faced the side in favor of the independence that called itself patriotic or revolutionary, against the side in favor of the integrity of the Spanish Monarchy.

The independence movements of Latin America acquired varied forms according to the conditions prevailing in each region.

The independence of the British colonies of North America in 1776 and the abdications of the Bourbon kings in 1808 before the French invasion of Spain, constitute two facts that encouraged independence in the weakened Spanish Monarchy.

In response to the enthronement of King José Bonaparte in Spain, between 1808 and 1810, government boards were installed that exercised sovereignty in the name of the abdicated King Ferdinand VII, both in the Iberian Peninsula and in the American territories. The resistance of the American boards to submit to all the governments formed in Spain radicalized the positions and led to the armed struggle between royalists and patriots. From 1810, several American territories began to declare independent national states under republican regimes, forming "liberating" armies, among which were the armies commanded by Hidalgo and Morelos in Mexico, and those of the Argentinian José de San Martín and the Venezuelan Simón Bolívar in South America.
