Final answer:
The primary purpose of the Georgia colony was to serve as a buffer between the other English colonies and the Spanish colony in Florida.
Step-by-step explanation:
The primary purpose of the Georgia colony, according to the charter of 1732, was to serve as a "buffer" between the other twelve English colonies and the Spanish colony in Florida.
The British wanted to establish a colony in this strategically important area to defend their settlements against Spanish aggression and maintain control over the region.
Georgia was seen as a garrison province that would protect the British from Spanish Florida and act as a military barrier between the British settlements and their imperial rivals.
