Seminole music

Seminole
The Seminole are a Native American people originally from Florida.
 Today, they principally live in Oklahoma with a minority in Florida, and comprise three federally recognized tribes: the Seminole Tribe of Oklahoma, the Seminole Tribe of Florida, and Miccosukee Tribe of Indians of Florida, as well as independent groups.
 The Seminole nation emerged in a process of ethnogenesis from various Native American groups who settled in Florida in the 18th century, most significantly northern Muscogee (Creeks) from what is now Georgia and Alabama.
 The word "Seminole" is derived from the Creek word "simanó-li", which may be itself be derived from the Spanish word "cimarrón", menaning "runaway" or "wild one".
Draining and development of the Everglades
The history of draining and development of the Everglades dates back to the 19th century.
 During the Second Seminole War beginning in 1836, the United States military's mission was to seek out Seminole people in the Everglades and capture or kill them.
 Those missions gave the military the opportunity to map land that seemed to frustrate and confound them at every turn.
 A national push for expansion and progress toward the latter part of the 19th century stimulated interest in draining the Everglades for agricultural use.
 According to historians, "From the middle of the nineteenth century to the middle of the twentieth century, the United States went through a period in which wetland removal was not questioned.
 Indeed, it was considered the proper thing to do."
Muscogee language
The Muscogee language (Mvskoke in Muscogee), also known as Creek, Seminole, Maskókî or Muskogee, is a Muskogean language spoken by Muscogee (Creek) and Seminole people, primarily in the U.S. states of Oklahoma and Florida.

Battle of Jupiter Inlet
The Battle of Jupiter Inlet occurred on January 15, 1838, between the Seminole Indians - Seminole Negro and the United States Navy.
 This was the first of a series of battles led by the US Navy in the area, also referred to as the First Battle of Loxahatchee.
 The battle started when Lt. Levin Powell led an expedition of 200 soldiers, sailors and marines, down the east coast of Florida.
 The Navy spotted a trail alongside the Jupiter Inlet, and seventy-five men were landed to find the Seminole camp nearby.
 The camp was led by Sam Jones, Ar-pi-uck-i, the spiritual medicine and war chief of the Miccosukee and Seminole people during the war.
 The officers that advanced on the camp were outnumbered and ambushed.
 After a long fight, the US retreated with five men killed in action and about twenty others wounded.

 Of 18,800 enrolled tribal members, 13,533 live within the state of Oklahoma.
 The tribe began to revive its government in 1936 under the Indian Reorganization Act.

Black Seminoles
The Black Seminoles are black Indians associated with the Seminole people in Florida and Oklahoma.
 They are the descendants of free blacks and of escaped slaves (called maroons) who allied with Seminole groups in Spanish Florida.
