Propprietary colonies were managed by the people who owned them.
Explanation:
Proprietary colonies were a type of English colony popular in North America that was granted by the king to an individual after a certain agreement. the method to carry out this strategy was by providing royal charters to his friends and those finding private investment to develop the colony with the self-colonial government of course under the authority of the crown. New Netherlands today new york, and Pennsylvania were two of these colonies. However, after the administration was found out of the favor of the colonies and the crown the self-government grant was removed from them and became crown colonies.
