A. as a defense against Spanish or French invasion of the Carolinas
Spanish held Florida as a colony and the French were on the other side of the Appalachian Mountains. The Carolinas was the money maker for Great Britain with plantations and a system of cash crops providing Britain with a mercantilism exchange.
Georgia was established as a colony to be a buffer zone between other European colonies and the Carolinas. The colony was established by James Oglethorpe and became a solution to overcrowding jails in England. Those jailed for less serious offenses were sent to Georgia to establish farm and the colony. Slavery was not allowed in the colony since the slaves running away or being targeted was a concern for the other southern colonies.
