What cultural alliance was formed by the Oneida, Mohawk, Onondaga, Seneca, and Cayuga?

The Iroquois Confederation, formed by the Oneida, Mohawk, Onondaga, Seneca, and Cayuga, is a significant cultural and political alliance among several Native American tribes in the northeastern region of North America. This confederation, also known as the Haudenosaunee or Six Nations, was established to promote peace, cooperation, and mutual defense among the member tribes.

The formation of this alliance was crucial for creating a unified front against external threats, particularly from European colonists and rival tribes. Decisions were made collectively in councils, underscoring the principles of democracy and representation long before European-style governance emerged. The Iroquois Confederation also played a vital role in influencing political thought in the United States, as its structure inspired some aspects of the U.S. Constitution.

The other choices—League of Nations, Pueblo Alliance, and Algonquin Tribe—do not correspond to this specific cultural and political alliance. The League of Nations was an international organization formed after World War I, the Pueblo Alliance refers to the coalition of Pueblo tribes in the southwestern United States, and the Algonquin Tribe represents a distinct group of Native Americans.
