Iroquoian linguistic family. Other Iroquoian tribal nations are Seneca, Mohawk, Oneida, Cuyuga, Onondaga, Tuscarora, Erie, and Susquehannock, plus several others that are now extinct.
As part of the same cultural/linguistic family, there are many customs that overlap between them. I am more familar with the Seneca than with other linguistically and culturally Iroquoisan tribal nations.
I noticed several similarities between the Seneca and Cherokee when watching the video, i.e. games, role and power of women, having both war and peace chiefs, the Green Corn Festival, governing councils, 3 sisters agriculture, clan structure, and wampum belts for recording treaties and keeping records of deals and transactions.
The original homeland of the Cherokee was in the southeast of what is now the US. Other Iroquoian tribal nations were in the northeast, primarily NY state and parts of Pa and Ohio. The Tuscarora were a southeastern tribe that moved north to join other Iroquoian tribes and escape wars with European Americans.
Because of the southeastern location of the Cherokee, they were influenced by the Mississippian Culture more closely than the northern Iroquois were.
Most people think of tribal societies as "wild," with very few or no social structures or rules. But all tribal societies, wherever they are, develop social structures, customs, and organized governing systems that they pass on for generations, modifying them as necessary. Some are simpler than others. Some are quite sophisticated.
