The Second Seminole War, also known as the Florida War, was a conflict from 1835 to 1842 in Florida between the United States and groups of people collectively known as Seminoles, consisting of American Indians and Black Indians. It was part of a series of conflicts called the Seminole Wars. The Second Seminole War, often referred to as the Seminole War, is regarded as "the longest and most costly of the Indian conflicts of the United States". After the Treaty of Payne's Landing in 1832 that called for the Seminole's removal from Florida, tensions rose until fierce hostilities occurred in the Dade battle in 1835. This conflict started the war. The Seminoles and the U.S. forces engaged in mostly small engagements for more than six years. By 1842, only a few hundred native peoples remained in Florida. Although no peace treaty was ever signed, the war was declared over on August 14, 1842.

The Yuchi people, also spelled Euchee and Uchee, are a Native American tribe based in Oklahoma. Their original homeland was in the southeast of the present United States.
