Tulsa was settled between 1828 and 1836 by the Lochapoka Band of Creek Native American tribe and most of Tulsa is still part of the territory of the Muscogee (Creek) Nation.[a]

Historically, a robust energy sector fueled Tulsa's economy; however, today the city has diversified and leading sectors include finance, aviation, telecommunications and technology. Two institutions of higher education within the city have sports teams at the NCAA Division I level: Oral Roberts University and the University of Tulsa. As well, the University of Oklahoma has a secondary campus at the Tulsa Schusterman Center, and Oklahoma State University has a secondary campus located in downtown Tulsa.
