War bonnets 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. In the Native American and First Nations communities that traditionally have these items of regalia, 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.

Headgear, headwear, or headdress is any element of clothing which is worn on one's head, including hats, helmets, turbans and many other types. Headgear is worn for many purposes, including protection against the elements, decoration, or for religious or cultural reasons, including social conventions.
