Florida's colonial history under British and Spanish rule was marked by significant changes in governance, economy, and society. From 1763 to 1821, control of Florida shifted between these European powers, shaping the region's development and setting the stage for its future as a U.S. territory and state. This period saw the introduction of new agricultural practices, expansion of the plantation system, and increased settlement. Relations with Native American tribes, particularly the Seminoles, were complex and often contentious, leading to conflicts that would continue into Florida's American era.
