Question: The Muscogee language is spoken by native Americans who, emerged by ethnogenesis, and settled in Florida in what century? 

full_context: Document 1: Choctaw: The Choctaw (In the Choctaw language, Chahta) are a Native American people originally occupying what is now the Southeastern United States (modern-day Alabama, Florida, Mississippi, and Louisiana). Their Choctaw language belongs to the Muskogean language family group.
Document 2: 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.
Document 3: Creek mythology: Creek mythology is related to a Creek Native American tribe who are originally from the southeastern United States, also known by their original name Muscogee (or Muskogee), the name they use to identify themselves today. "Mvskoke" is their name in traditional spelling. Modern Muscogees live primarily in Oklahoma, Alabama, Georgia, and Florida. Their language, "Mvskoke", is a member of the Creek branch of the Muskogean language family. The Seminole are close kin to the Muscogee and speak a Creek language as well. The Creeks were considered one of the Five Civilized Tribes. After the Creek War many of the Creeks escaped to Florida to create the Seminole.
Document 4: Kialegee Tribal Town: The Kialegee Tribal Town is a federally recognized Native American tribe in Oklahoma, as well as a traditional township within the former Muscogee Creek Confederacy in the American Southeast. Tribal members pride themselves on retaining their traditions and many still speak their traditional Muscogee language. The name "Kialegee" comes from the Muscogee word, "eka-lache", meaning "head left."
Document 5: Alabama language: Alabama (also known as Alibamu) is a Native American language, spoken by the Alabama-Coushatta tribe of Texas. It was once spoken by the Alabama-Quassarte Tribal Town of Oklahoma, but there are no more Alabama speakers in Oklahoma. It is a Muskogean language, and is believed to have been related to the Muklasa and Tuskegee languages, which are no longer extant. Alabama is closely related to Koasati and Apalachee, and more distantly to other Muskogean languages like Hitchiti, Chickasaw and Choctaw.
Document 6: Apalachicola people: The Apalachicola (also called Pallachacola, ) were a group of Native Americans related to the Muscogee people. They spoke a Muskogean language related to Hitchiti. They lived along the Apalachicola River in present-day Florida. Their name derives probably from Hitchiti Apalachicoli or Muskogee Apalachicolo, signifying apparently "People of the other side", with reference probably to the Apalachicola River or some nearby stream.
Document 7: 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".
Document 8: Seminole Nation of Oklahoma: The Seminole Nation of Oklahoma is a federally recognized Native American tribe based in the U.S. state of Oklahoma. It is the largest of the three federally recognized Seminole governments, which include the Seminole Tribe of Florida and the Miccosukee Tribe of Indians of Florida. Its members are descendants of the 3,000 Seminoles who were forcibly removed from Florida to Indian Territory, along with 800 Black Seminoles, after the Second Seminole War. The Seminole Nation of Oklahoma is headquartered in Wewoka within Seminole County, Oklahoma. 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. While its reservation was originally larger, today the tribal jurisdictional area covers Seminole County, Oklahoma, within which it has a variety of properties.
Document 9: Thlopthlocco Tribal Town: Thlopthlocco Tribal Town is both a federally recognized Native American tribe and a traditional township of Muscogee Creek Indians, based in Oklahoma. The tribe's native language is Mvskoke, also called Creek.
Document 10: Seminole Tribe of Florida: The Seminole Tribe of Florida is a federally recognized Seminole tribe based in the U.S. state of Florida. Together with the Seminole Nation of Oklahoma and the Miccosukee Tribe of Indians of Florida, it is one of three federally recognized Seminole entities. It received that status in 1957; today it has six Indian reservations in Florida.
Document 11: Leading chief of the Seminoles: There were four leading chiefs of the Seminole, a Native American tribe that formed in what was then Spanish Florida in present-day United States. They were leaders between the time the tribe organized in the mid-18th century until Micanopy and many Seminole were removed to Indian Territory in the 1830s following the Second Seminole War.
Document 12: Mikasuki language: The Mikasuki language (also Miccosukee, Mikisúkî or Hitchiti-Mikasuki) is a Muskogean language spoken by around 500 people in southern Florida. It is part of the Eastern branch of Muskogean languages, along with Creek-Seminole and Apalachee–Alabama–Koasati. It is spoken by the Miccosukee tribe and many Florida Seminole. The extinct Hitchiti was a mutually-intelligible dialect.
Document 13: Osceola: Osceola (1804 – January 30, 1838), born as Billy Powell, became an influential leader of the Seminole in Florida. Of mixed parentage, Creek, Scots-Irish, black, and English, he was raised as a Creek by his mother, as the tribe had a matrilineal kinship system. They migrated to Florida when he was a child, with other Red Stick refugees, after their defeat in 1814 in the Creek Wars.
Document 14: State of Sequoyah: The State of Sequoyah was a proposed state to be established from the Indian Territory in the eastern part of present-day Oklahoma. In 1905, with the end of tribal governments looming (as prescribed by the Curtis Act of 1898), Native Americans of the Five Civilized Tribes—the Cherokee, Chickasaw, Choctaw, Creek (Muscogee), and Seminole—in Indian Territory proposed to create a state as a means to retain control of their lands. Their intention was to have a state under Native American constitution and governance. The proposed state was to be named in honor of Sequoyah, the Cherokee who created a writing system in 1825 for the Cherokee language.
Document 15: Timucua language: Timucua is a language isolate formerly spoken in northern and central Florida and southern Georgia by the Timucua people. Timucua was the primary language used in the area at the time of Spanish colonization in Florida. Linguistic and archaeological studies suggest that it may have been spoken from around 2000 BC. Differences among the nine or ten Timucua dialects were slight, and appeared to serve mostly to delineate tribal boundaries. Some linguists suggest that the Tawasa of what is now northern Alabama may have spoken Timucua, but this is disputed.
