Final answer:
Proprietary colonies were governed by a proprietor who had ultimate authority. These colonies were similar to fiefdoms in that the proprietor controlled all actions and institutions of government. However, many proprietary colonies eventually became royal colonies.
Step-by-step explanation:
During the colonial period, there were three models of government in the British colonies: the royal colony, the proprietary colony, and the corporate colony. In the proprietary colony, the proprietor chose the governor with the crown's approval. These colonies were similar to fiefdoms in that the proprietors had ultimate authority over their colonies, controlling all actions and institutions of government. However, by the early eighteenth century, many proprietary colonies had become royal colonies, under the direct control of the English Crown.
