Florida was the northern bastion of Spain’s New World empire from an early period; and, except for brief British possession (1763-1783), the land was hers for almost three hundred years. The era following 1783, when Great Britain returned Florida to Spain, until 1821, when Florida became United States territory, is known as the second Spanish period of Florida history.
