Essentially, the Proclamation of 1763, issued by King George III, prevented colonists from settling past the so-called <em>proclamation line</em>, west of the Appalachian mountains, even though part of that land had already been assigned, and it also prohibited the purchase of land from American Indians by private hands.
However, it benefited Georgia by granting the state a very significant amount of land. For instance, it gave it all the lands between the rivers Altamaha and St. Marys, therefore extending its southern border. In addition, two of the four new colonies that were created after the Proclamation (East and West Florida) were located south of Georgia. Between those two Floridas and Georgia there was a very large area of undesignated land, which soon afterwards was also granted to Georgia.
