On June 9, 1732, King George II granted a royal charter to the Trustees for Establishing the Colony of Georgia in America.

The Library of Congress explains that Oglethorpe had become concerned about poor and debt-ridden people in London and supported the idea of giving them a fresh start in America. Georgia was also intended to serve as a defensive buffer between South Carolina and Spanish Florida.
