Which colony had strict regulations including bans on drinking rum and slavery before becoming a royal colony?

Georgia is the correct choice, as it was established in 1732 with specific regulations intended to create a "fresh start" for the impoverished and those in debt, particularly from England. One of the colony's founders, James Oglethorpe, implemented restrictions such as prohibiting the importation of rum and banning slavery in an effort to promote a more virtuous society among the settlers.

These regulations were part of Oglethorpe's vision for Georgia, which aimed to serve as a buffer against Spanish Florida and a place for those seeking refuge. However, these bans would later be lifted as the colony grew, leading to a shift in its economic practices once it became a royal colony in 1752.

In contrast, the other colonies listed did not have such strict limitations on alcohol or slavery during their early years or did not have the same foundational purpose that involved these sorts of restrictions.
