Final answer:
In the context of Hiawatha and the Iroquois Confederacy, the Confederacy itself included the Mohawk, Seneca, Onondaga, Oneida, and Cayuga nations, with the Tuscarora joining later. The 'first tribe' Hiawatha established is not specified, but the Mohawk and Onondaga were significant in confederacy leadership.
Step-by-step explanation:
The question of which tribe Hiawatha establishes first pertains to the Iroquois Confederacy, also known as the Haudenosaunee. Hiawatha played a key role in the formation of this confederacy, and while the specific 'first tribe' within this confederacy is not clearly defined by historical accounts, the Confederacy itself was made up of five (later six) nations: the Mohawk, Seneca, Onondaga, Oneida, and Cayuga, with the Tuscarora joining later. These tribes were already established before the confederacy.
Historically, the Iroquois Confederacy was a significant political and military organization, known for its sophisticated form of governance and its influence of democratic ideals. Among the founding tribes, it was likely that the Mohawk or the Onondaga were instrumental in early negotiations given their prominent roles within the confederacy.
