Final answer:
Spain's colony in the New World was called New Spain, a vast territory under Spanish control following early colonization efforts in the Americas.
Step-by-step explanation:
Spain's colony in the New World was called New Spain. This name encompasses the vast territories that were under Spanish control following their early and extensive colonization efforts in the Americas. Spain was one of the first European powers to establish colonies in the New World, spearheading the era of Atlantic exploration and setting up the first enduring settlements before England and France. While England did establish Jamestown as its first permanent colony in what later became the United States, this was not the name of Spain's colonies in the Americas. New France was the name given to the northern regions of North America explored and claimed by France.
