Questioning the habitual narrative that sees the Americas as a logical extension of the Old World, Herzog portrays Spain and Portugal on both sides of the Atlantic as one unified imperial space. She begins in the Americas, where Iberian conquerors had to decide who could settle the land, who could harvest fruit and cut timber, and who had river rights for travel and trade. The presence of indigenous peoples as enemies to vanquish or allies to befriend, along with the vastness of the land, complicated the picture, as did the promise of unlimited wealth. In Europe, meanwhile, the formation and re-formation of boundaries could last centuries, as ancient entitlements clashed with evolving economic conditions and changing political views and juridical doctrines regarding how land could be acquired and maintained.

Territorial control was always subject to negotiation, as neighbors and outsiders, in their quotidian interactions, carved out and defended new frontiers of possession.
