Question:
Cream were a 1960s British rock power trio consisting of drummer Ginger Baker, guitarist/singer Eric Clapton and lead singer/bassist Jack Bruce. The group's third album, Wheels of Fire (1968), was the world's first platinum-selling double album. The band is widely regarded as the world's first successful supergroup. In their career, they sold more than 15 million copies of their albums worldwide.
In 1968 came the band's third release, Wheels of Fire, which topped the American charts. Still a relative novelty, the "double album" of two LP discs was well suited to extended solos. Wheels of Fire studio recordings showcased the band moving slightly away from the blues and more towards a semi-progressive rock style highlighted by odd time signatures and various orchestral instruments. However, the band did record Howlin' Wolf's "Sitting on Top of the World" and Albert King's "Born Under a Bad Sign". According to a BBC interview with Clapton, the record company, also handling Albert King, asked the band to cover "Born Under a Bad Sign", which became a popular track off the record. The opening song, "White Room", became a radio staple. Another song, "Politician", was written by the band while waiting to perform live at the BBC. The album's second disc featured three live recordings from the Winterland Ballroom and one from the Fillmore. Clapton's second solo from "Crossroads" has made it to the top 20 in multiple "greatest guitar solo" lists.  After the completion of Wheels of Fire in mid-1968, the band members had had enough and wanted to go their separate ways. Baker stated in a 2006 interview with Music Mart magazine, "It just got to the point where Eric said to me: 'I've had enough of this,' and I said so have I. I couldn't stand it. The last year with Cream was just agony. It damaged my hearing permanently, and today I've still got a hearing problem because of the sheer volume throughout the last year of Cream. But it didn't start off like that. In 1966, it was great. It was really a wonderful experience musically, and it just went into the realms of stupidity." Bruce and Baker's combustible relationship proved even worse as a result of the strain put upon the band by non-stop touring, forcing Clapton to play the perpetual role of peacekeeper.  Clapton had also become interested in the music of Bob Dylan's former backing group, now known as the Band, and their debut album, Music from Big Pink, which proved to be a welcome breath of fresh air, to Clapton, in comparison to the incense and psychedelia that had defined Cream. Furthermore, he had read a scathing Cream review in Rolling Stone, a publication he had much admired, in which the reviewer, Jon Landau, called him a "master of the blues cliche." In the wake of that article, Clapton wanted to end Cream and pursue a different musical direction.  At the beginning of their farewell tour on 4 October 1968, in Oakland, California, nearly the entire set consisted of songs from Wheels of Fire: "White Room", "Politician", "Crossroads", "Spoonful", "Deserted Cities of the Heart", and "Passing the Time" taking the place of "Toad" for a drum solo. "Passing the Time" and "Deserted Cities" were quickly removed from the setlist and replaced by "Sitting on Top of the World" and "Toad".

Answer the question at the end by quoting:

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. Historically, the Black Seminoles lived mostly in distinct bands near the Native American Seminole. Some were held as slaves of particular Seminole leaders; but they had more freedom than did slaves held by whites in the South and by other Native American tribes, including the right to bear arms.
Throughout the period, several hundred Black Seminoles remained in the Indian Territory (present-day Oklahoma). Because most of the Seminole and the other Five Civilized Tribes supported the Confederacy during the American Civil War, in 1866 the US required new peace treaties with them. The US required the tribes emancipate any slaves and extend to the freedmen full citizenship rights in the tribes if they chose to stay in Indian Territory. In the late nineteenth century, Seminole Freedmen thrived in towns near the Seminole communities on the reservation. Most had not been living as slaves to the Indians before the war. They lived --as their descendants still do-- in and around Wewoka, Oklahoma, the community founded in 1849 by John Horse as a black settlement. Today it is the capital of the federally recognized Seminole Nation of Oklahoma.  Following the Civil War, some Freedmen's leaders in Indian Territory practiced polygyny, as did ethnic African leaders in other diaspora communities. In 1900 there were 1,000 Freedmen listed in the population of the Seminole Nation in Indian Territory, about one-third of the total. By the time of the Dawes Rolls, there were numerous female-headed households registered. The Freedmen's towns were made up of large, closely connected families.  After allotment, "[f]reedmen, unlike their [Indian] peers on the blood roll, were permitted to sell their land without clearing the transaction through the Indian Bureau. That made the poorly educated Freedmen easy marks for white settlers migrating from the Deep South." Numerous Seminole Freedmen lost their land in the early decades after allotment, and some moved to urban areas. Others left the state because of its conditions of racial segregation. As US citizens, they were exposed to the harsher racial laws of Oklahoma.  Since 1954, the Freedmen have been included in the constitution of the Seminole Nation of Oklahoma. They have two bands, each representing more than one town and named for 19th-century band leaders: the Cesar Bruner band covers towns south of Little River; the Dosar Barkus covers the several towns located north of the river. Each of the bands elects two representatives to the General Council of the Seminole Nation.

What was their Indian territory?
(present-day Oklahoma).
