This work investigates the complex socio-political transformation of the Canary Islands following their integration into the Castilian crown during the early sixteenth century. Felipe Fernández-Armesto, a distinguished historian of global exploration and colonial expansion, utilizes extensive archival research to reconstruct the transition from indigenous societies to a colonial framework. The book argues that the islands served as a critical laboratory for the administrative, economic, and social structures that would later be exported to the Americas. By analyzing the interplay between settlers, indigenous populations, and imperial authorities, the author provides a rigorous examination of early modern colonial state-building.

Scholars recognize this monograph as a foundational text for understanding the early stages of Spanish imperial expansion. Readers frequently note the academic density of the prose, which provides a meticulous account of the institutional development of the Canary Islands.
