Name of the grouping the Iroquois people had

The correct answer is - Iroquois Confederacy/Iroquois League/Five Nations.

The Iroquois were a confederation of five tribes. They were located in what is now the state of New York. This Native American confederacy was initially named by the French as the Iroquois League, the British than renamed it into the Iroquois Confederacy, and later into the Five Nations.

The five tribes that made out this confederacy were the Seneka, Mohawk, Oneida, Onondanga, and Cayuga.

All of these tribes were war-like. They were very tough, and constantly engaged into warfare against the rival tribes or confederacies. The young boys were trained for warfare from very early age. They were having a lot of training, especially for making them tougher, being resilient to pain, and to be excellent fighters.
