How did Mississippian villages protect themselves

before the arrival of the europeans, how did mississippian villages protect themselves?

i believe the answer is d- they built palisades and moats

explanation :  some of the mississippian villages had defensive structures but not all of the villages had these defensive structures to protect themselves with these had usually  came in the forms of  poll walls.  also known as a palisade. sometimes there was even a ditch outside the wall but not all the time  these things helped keep unwelcome things  out such as other people and animals  from going inside the village . some towns had even featured mounds , a mound is a natural elevation of the earth  used for defensive work or a dam.

example of a mound- the  slightly elevated ground that a baseball pitcher delivers a ball.

another example of a mound is - a small  hill usually made up of rocks  and or dirt  that you can climb on  

but in this case the mound that i'm talking about is what the indians used which was a elevated part of the earth used to defend their villages from people and animals entering.

oh and a moat is  a ditch filled with water  that surrounds a building or a town

it is also something that can be used as a form of  defense  but these moats can also be and or act like a sewer.

i also used process of elimination

c wouldn't make sense  because they could not use guns or ammunition since  they did not lay hands or could get them just yet until the middle of the 1600's  during early days of the fur trade.

b would not be correct either because  the tribes were competing for resources that were scarce and ending up  coming into conflict with each other  which resulted in a battle which had also gotten  europeans  involved called the  black hawk war .

a wouldn't be correct either because  american indians did not have military forces .

so therefore the answer would be d- they built palisades and moats.

demand is the need and oportunity to buy a given good or service.
