Final answer:
Hiawatha's aim in uniting the five tribes was to create the Iroquois Confederacy, enabling unified decision-making, peace, and strength against external threats.
Step-by-step explanation:
The purpose of Hiawatha in uniting the five tribes—Mohawk, Oneida, Onondaga, Cayuga, and Seneca—was to form a powerful and influential political entity known as the Iroquois Confederacy or Haudenosaunee. This confederacy established a collective governance structure that allowed the tribes to efficiently make decisions, maintain peace among themselves, and present a unified front against external threats such as European colonial powers and other Native American groups. The formation of the Iroquois Confederacy was a significant political strategy that enhanced the security and prosperity of the comprised nations through unified action and shared decision-making.
