Final answer:
King Charles II made William Penn the proprietor of Pennsylvania in 1681.
Step-by-step explanation:
King Charles II made William Penn the proprietor of Pennsylvania. In 1681, Charles II granted Penn a charter, giving him control of approximately 45,000 acres of land. This land became the colony of Pennsylvania, named after Penn's late father who had served the crown. Despite Penn's Quaker beliefs, which discouraged vanity, Charles II chose to honor Penn's father and his loyal service to the crown by naming the colony after him.
