Who was the first king of Spain?

• A. Charles V
• B. Ferdinand II
• C. Philip II
• D. Isabella I

Answer: (A)

The idea being tested is when a single monarch first ruled over a unified Spain. The marriage of Isabella I of Castile and Ferdinand II of Aragon began the political union of the two kingdoms, but they ruled their realms separately for a time and Spain as a single monarchy didn’t have one king yet. The moment that changes is when Charles V ascended to the thrones of Castile and Aragon in 1516, becoming a single ruler over both realms. He is also known as Charles I of Spain, so this marks the first time one king governed what people refer to as Spain. That’s why Charles V is the right answer. The other figures were important leaders, but they did not preside over a united Spanish crown in the same way.
