The Spanish American wars of independence took place throughout Spanish America during the early 19th century, with the aim of political independence from Spanish rule. Struggles for sovereignty in both hemispheres began shortly after the outbreak of the Peninsular War as a front in the larger Napoleonic Wars, between royalists who favored a unitary monarchy, and patriots who favored either plural monarchies or republics. Thus, the strict period of military campaigns would go from the Battle of Chacaltaya (1809), in present-day Bolivia, to the Battle of Tampico (1829) in Mexico.

Spanish America refers to the Spanish territories in the Americas during the Spanish colonization of the Americas. The term "Spanish America" was specifically used during the territories' imperial era between 15th and 19th centuries. To the end of its imperial rule, Spain called its overseas possessions in the Americas and the Philippines "The Indies", an enduring remnant of Columbus's notion that he had reached Asia by sailing west. When these territories reach a high level of importance, the crown established the Council of the Indies in 1524, following the conquest of the Aztec Empire, asserting permanent royal control over its possessions. Regions with dense indigenous populations and sources of mineral wealth attracting Spanish settlers became colonial centers, while those without such resources were peripheral to crown interest. Once regions incorporated into the empire and their importance assessed, overseas possessions came under stronger or weaker crown control.
