The Georgia Militia existed from 1733 to 1879. It was originally planned by General James Oglethorpe before the founding of the Province of Georgia, the Crown colony that would become the U.S. state of Georgia. One reason for the founding of the colony was to act as a buffer between the Spanish settlements in Florida and the British colonies to the north. For background with respect to the region's Native Americans, see the Yamasee War (1715–1717) and Cherokee–American wars (1776–1795). Campaigns included the American Revolutionary War, 1775–1783, the Oconee Wars, 1787–1797, The Embargo Wars, 1807–1812, the War of 1812, 1812–1815, the First Seminole War, 1817–1819, the Second Seminole War, 1835–1843, the Creek War of 1836, 1836–1837, the Cherokee Disturbances and Cherokee Removal, 1836–1838, and the Mexican–American War, 1846–1848.
