Spanish Kings Expand Their Rule
Key Idea
In the 1500s, Spain became Europe's most powerful nation. The Habsburg ruler Charles V inherited a massive empire that included Spain, the Netherlands, and large parts of the Americas. He worked to centralize his control over these widespread lands.
Spanish monarchs used several strategies to strengthen their rule. They fought wars to expand their territory and used carefully planned marriages to form alliances and gain new lands. They also saw themselves as defenders of the Catholic Church, using religion to unite their subjects.
