Why did the confederacy make the Iroquois more powerful?

The Confederacy, particularly the Iroquois Confederacy, strengthened the power of the Iroquois by uniting several tribes under a common governance system, promoting cooperation and mutual defense. This unity allowed them to effectively negotiate with European powers and resist encroachment on their lands. Additionally, their political organization and strategic alliances enhanced their influence in regional conflicts, making them a formidable force among Native American tribes and against colonial expansion.
