How Native American culture defended themselves?

Answer 1

I guess you are asking about protection in warfare.

A type of armour was used by some tribes; some even developed a type of helmet and many carried shields. The armour was made of wooden slats tied together with sinew - this was used by some of the early eastern woodlands warriors such as the Huron. One illustration of a Huron warrior shows him covered from neck to knee front and back by two long sections of this type of armour.

On the north-west coast wooden helmets were worn by some warriors, carved into tribal, clan or family animal totems.

Shields appear to have been rarely used by the eastern woodland tribes, but they were a regular feature of warriors in the interior, almost always circular in shape and cut from the thickest part of a bull buffalo's hide. A thinner painted hide cover with protective designs would often be used as a covering - or sometimes the shield itself was painted and the plain cover was only removed just before going into battle.

Northern Plains shields used by the Plains Cree, Blackfoot and their neighbours were, before horses became widely available, made very large and circular. Warriors on foot formed two battle lines at a distance from each other, kneeling behind these shields and shooting arrows at each other - very few casualties resulted. After horses became plentiful shields reduced in size to around 18 to 26 inches across, always with a long strap attached to sling over one shoulder.

Some Plains warriors wore thick hide shirts into battle. The Crows sometimes used such an item, but strangely cut fairly short so it did not reach the waist.

West Coast warriors sometimes wore shirts of thick hide, tree bark or wood as a kind of armour to ward off enemy arrows.
