Why did native americans raid anglo american settlements?

It was to take back their land. This was the war between them and it was called The Indian Wars. It resulted from competition for resources and land ownership as Europeans, Americans and Canadians invaded a territory which had been inhabited by Native Americans. 

1. One historical development that may have influenced the views expressed in the speech is:

The Religious divisions following the creation of Huguenot churches,  Calvinism, and Protestantism in Catholic France.

Explanation:

Religious intolerance can split a kingdom.  It can also set brothers against one another.  All religionists must embrace peace and recognize the rights of non-believers and different religionists to co-exist.  People should never kill in the name of God.  God has never authorized such killings.  Religious intolerance in parts of Europe during the middle ages makes for horrific news.  It should never be allowed to rear its ugly head again.
