Seminole Wars

The Seminole Wars (also known as the Florida Wars) were a series of three military conflicts between the United States and the Seminoles that took place in Florida between about 1816 and 1858. The Seminoles are a Native American nation which coalesced in northern Florida during the early 1700s, when the territory was still a Spanish colonial possession. Tensions grew between the Seminoles and American settlers in the newly independent United States in the early 1800s, mainly because enslaved people regularly fled from Georgia into Spanish Florida, prompting slaveowners to conduct slave raids across the border. What began as small cross-border skirmishes became the First Seminole War, as Andrew Jackson led U.S. forces into Florida—despite Spanish objections—to pursue the Seminoles. Jackson's forces destroyed several Seminole, Mikasuki and Black Seminole towns, as well as captured San Marcos de Apalache and briefly occupied Pensacola before withdrawing in 1818. In 1819 the U.S. and Spain agreed to transfer Florida in the Adams–Onís Treaty.

The United States gained possession of Florida in 1821 and coerced the Seminoles into leaving their lands in the Florida panhandle for a large Indian reservation in the center of the peninsula per the Treaty of Moultrie Creek. In 1832 by the Treaty of Payne's Landing, however, the federal government under United States President Andrew Jackson demanded that they leave Florida altogether and relocate to Indian Territory (modern day Oklahoma) as per the Indian Removal Act of 1830. Those who refused to move resisted violently, leading to the Second Seminole War (1835–1842), which was by far the longest and most wide-ranging of the three conflicts. Initially, less than 2,000 Seminole warriors employed hit-and-run guerilla warfare tactics and knowledge of the land to evade and frustrate a combined U.S. Army and Marine force that grew to over 30,000. Instead of continuing to pursue these small bands, American commanders eventually changed their strategy and focused on seeking out and destroying hidden Seminole villages and crops, putting increasing pressure on resisters to surrender or starve with their families.

By 1842, 3,612 Seminoles had relocated to the Indian Territory. A minority of about 350 to 500 remained in Florida, where they were allowed to remain in an uneasy truce. Tensions over new settlement in the state under the Armed Occupation Act of 1842 south of Tampa led to renewed hostilities, and the Third Seminole War broke out in 1855. By the cessation of active fighting in 1858, the few remaining bands of Seminoles in Florida had fled deep into the Everglades to land unwanted by American settlers.

Altogether, the Seminole Wars were the longest of the American Indian Wars while also being the most expensive.
