Final answer:
James Oglethorpe aimed to establish a colony in the New World both as a buffer against Spanish Florida and to offer a new start for English debtors, addressing the overcrowding of debtors' prisons.
Step-by-step explanation:
James Oglethorpe most likely came up with the idea to move English debtors to his colony in the New World in order to create a buffer zone against Spanish Florida, and to address England's problem of overcrowded debtors' prisons. Oglethorpe was a social reformer who saw in Georgia a dual opportunity: it could protect the British colonies to the north from Spanish incursions, and also provide a new start for the 'worthy poor' of England. As a military buffer, the colonists would serve as a militia force against Spanish threats, and as a social reform, the colony offered a way out for those imprisoned for debts. The land was to be distributed in fifty-acre plots, facilitating the establishment of smallholding farms, which formed the backbone of the plan for the colony.
