[Q]: Context_1 : The Dancing Rabbit Creek Treaty Site is a historic Choctaw Native American gathering place in rural Noxubee County, Mississippi. Located near a freshwater spring above the floodplain of Dancing Rabbit Creek in the southwestern part of the county, it was the site of a treaty negotiation between the Choctaw and the federal government in 1830, resulting in the Treaty of Dancing Rabbit Creek, in which the Choctaw agreed to surrender their ancestral lands for territory in what is now Oklahoma. It was the first treaty negotiated after passage of the Indian Removal Act, and served as a model for other treaties passed pursuant to that act. It also led to the Choctaw Trail of Tears. The site, now marked by a stone memorial and a small Choctaw cemetery, was designated a National Historic Landmark in 1996. Context_2 : 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". Context_3 : Doaksville is a former settlement, now a ghost town, located in present-day Choctaw County, Oklahoma. It was founded between 1824 and 1831, by people of the Choctaw Indian tribe who were forced to leave their homes in the Southeastern United States and relocate in an area designated in for their resettlement in Indian Territory. The community was named for Joseph Doak, co-owner of the local trading post. The town flourished until the U.S. Army abandoned nearby Fort Towson in 1854, though it remained as the Choctaw capital until 1859, then declined precipitately after being bypassed by a new railroad in 1870. It is now a ghost town and an archaeological preservation site.

Their Choctaw language belongs to the Muskogean language family group. Context_5 : The Floridas was a region of the southeastern United States comprising the historical colonies of East Florida and West Florida. The borders of East and West Florida varied. In 1783, when Spain acquired West Florida and re-acquired East Florida from Great Britain through the Peace of Paris (1783), the eastern British boundary of West Florida was the Apalachicola River, but Spain in 1785 moved it eastward to the Suwannee River. The purpose was to transfer San Marcos and the district of Apalachee from East Florida to West Florida. From 1810 to 1813, the United States extended piecemeal control over the part of West Florida that comprised the modern-day Gulf coasts of Alabama and Mississippi and the Florida Parishes of Louisiana. After the ratification of the Adams-Onis Treaty in 1821 the United States combined East Florida and what had been the remaining Spanish-controlled rump of West Florida into the territory that comprised modern-day Florida. Context_6 : The Treaty of Doak's Stand (7 Stat. 210, also known as Treaty with the Choctaw) was signed on October 18, 1820 (proclaimed on January 8, 1821) between the United States and the Choctaw Indian tribe. Based on the terms of the accord, the Choctaw agreed to give up approximately one-half of their remaining Choctaw homeland. In October 1820, Andrew Jackson and Thomas Hinds were sent as commissioners who represented the United States to negotiate a treaty to surrender a portion of Choctaw country in Mississippi. They met with tribal representatives at Doak's Stand on the Natchez Trace. They met with the chiefs Pushmataha, Mushulatubbee, and Apuckshunubbee, who represented the three major regional divisions of the Choctaw. Chiefs of the towns and other prominent men accompanied them, such as Colonel Silas Dinsmoor. Context_7 : The culture of the Choctaw has greatly evolved over the centuries combining mostly European-American influences; however, interaction with Spain, France, and England greatly shaped it as well.

Context_9 : Yowani (probably from the word for caterpillar) ('Yguanes/Yugani/Iguanes-Spanish') is a branch of the Choctaw tribe ". The Yowani were named for their village, the reason for the founding of a trading post and what became the European-American town of Shubuta, Mississippi nearby. The Yowani continued to expand their holdings, eventually venturing into Louisiana, where they established close ties with the Caddo and adopted many of the Caddo customs. When Louisiana became part of the United States under the Louisiana Purchase in 1803, many of the Indian tribes in the territory wanted to emigrate to less hostile environs. Spain agreed to allow the Yowanis and the Alabama-Coushatta to move to Spanish Texas. In 1824, a second group of Yowani received permission from Mexico to establish villages in Texas. The Yowani gradually abandoned their original Mississippi homelands, and by 1850 most Yowani lived in Texas, Indian Territory, or in Rapides Parish, Louisiana. Context_10 : Choctaw mythology is related to Choctaws, a Native American tribe originally from the Southeastern United States (Mississippi, Alabama, and Louisiana).
