Final answer:
Holy Roman Emperor Charles V granted Malta to the Knights of Malta who were required to send a Maltese Falcon as a tribute annually.
Step-by-step explanation:
The country that was given by Holy Roman Emperor Charles V to the Knights Hospitaller (also known as the Knights of Malta) after they were driven from Rhodes was Malta.
The knights were granted control over Malta, with the condition of sending a Maltese Falcon as a tribute to Charles' viceroy in Sicily every year.
The Knights Hospitaller were a chivalric order that played a significant role throughout the Crusades and later in the defense of Christian territories in the Mediterranean.
