War bonnets (also called warbonnets or headdresses) are feathered headgear traditionally worn by male leaders of the American Plains Indians Nations who have earned a place of great respect in their tribe. Originally they were sometimes worn into battle, but they are now primarily used for ceremonial occasions. They are seen as items of great spiritual and political importance, only to be worn by those who have earned the right and honour through formal recognition by their People.
Native American tribes consider the presentation of an eagle feather to be one of their highest marks of respect. Any honored person must have earned their feather through selfless acts of courage and honour, or been gifted them in gratitude for their work or service to their tribe. Traditional deeds that brought honour would include acts of valor in battle, but also political and diplomatic gains or acts that helped their community survive and prosper. The esteem attached to eagle feathers was so high that in many cases, such as a warrior (e.g. Dog Soldiers of the Cheyenne), only two or three honour feathers might be awarded in their whole lifetime. Historically, the warrior who was the first to touch an enemy in battle and escape unscathed received an eagle feather. When enough feathers were collected, they might be incorporated into a headdress or some other form of worn regalia. Headdresses were usually reserved exclusively for the tribe's chosen political and spiritual leaders.
Roman Nose, who was one of the most influential Cheyenne warriors of the Plain Indian Wars of the 1860s, was known for his illustrious warbonnet that was said to protect him during battle. Several instances record how while wearing his war bonnet, he rode back and forth before soldiers of the United States Army and, despite being fired upon, was left unscathed.
While women have traditional regalia that can include other types of headdresses, historically women did not wear the Plains warbonnet. However, in recent years a few Indigenous women who have attained a very high level of respect in their communities have been ceremonially gifted with headdresses of the type that were formerly only worn by men.
