The Spanish diaspora consists of Spanish people and their descendants who emigrated from Spain. In the Americas, the term may refer to those of Spanish nationality living there; "Hispanic" is usually a more appropriate term to describe the general Spanish-speaking populations of the Americas together with those in Spain. The diaspora is concentrated in places that were part of the Spanish Empire. Countries with sizeable populations are Argentina, Bolivia, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, Venezuela, and, to a lesser extent, Brazil, Belize, Haiti, United States, Canada and the rest of Europe. According to the latest data from the Instituto Nacional de Estadística's Register of Spaniards Resident Abroad (PERE), "the number of people with Spanish nationality living abroad reached 2,742,605 on January 1, 2022, an increase of 3.3% (87,882 people) with respect to the data from the same day last year". Castile, under the reign of Henry III, began the colonization of the Canary Islands in 1402, authorizing under feudal agreement to Norman noblemen Jean de Béthencourt. The conquest of the Canary Islands, inhabited by Guanche people, was only finished when the armies of the Crown of Castille won, in long and bloody wars, the islands of Gran Canaria (1478–1483), La Palma (1492–1493) and Tenerife (1494–1496). The marriage of the Reyes Católicos (Ferdinand II of Aragon and Isabella I of Castile) created a confederation of reigns, each with their own administrations, but ruled by a common monarchy. According to Henry Kamen, it was only after centuries of a common rule that these separated realms formed a fully unified state. In 1492, Spain drove out the last Moorish king of Granada. After their victory, the Catholic monarchs negotiated with Christopher Columbus, a Genoese sailor attempting to reach Cipangu by sailing west. Castile was already engaged in a race of exploration with Portugal to reach the Far East by sea when Columbus made his bold proposal to Isabella.
