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.

The Bourbon Reforms consisted of political and economic changes promulgated by the Spanish Crown under various kings of the House of Bourbon, since 1700, mainly in the 18th century. The beginning of the new Crown's power with clear lines of authority to officials contrasted to the complex system of government that evolved under the Habsburg monarchs. For example, the crown pursued state predominance over the Catholic Church, pushed economic reforms, and placed power solely into the hands of civil officials.
