How did Spain structure its American empire?

Answer 1

Spain built its American Empire by first subdividing it into Viceroyalties: New Spain, New Granada, Rio de la Plata, and Peru. These Viceroyalties would be led by Peninsulares, who were Spaniards born in Spain and moved to the New World to govern those areas. The Peninsulares would also have top-level bureaucrats who were also Peninsulares. The children of the Peninsulares, called criollos/creoles, were generally allowed economic freedom, even though they lacked political power. The economic engine of the colonies depended on the terrain and resources. In flatter, warmer regions, there were large sugarcane, tobacco, and cotton plantations. In more mountainous areas, there were vast gold and silver mines. The plantations were generally worked by African slaves and the mines were typically worked by Indigenous Peoples.

Answer 2

Spain structured the American empire by not freeing the slaves and taking more and more land . so Cortes and Pizarro helped structure Americas as well
