Question

The _ was formed to defend against native Americans

Answer 1

American Indians culture had been stripped away by measures like the Dawes Act, which had ended tribal government and authorized the sale of tribal land to individuals. Between the years 1887 (the year the Dawes Act came into effect) and 1934 (known as the "Allotment era") the government took over 90 million acres (360,000 km2) of tribal lands that were previously guaranteed to tribes by treaties and federal law. Henry Dawes who authored the Dawes Act, was quoted as saying that to be civilized, one must "wear civilized clothes...cultivate the ground, live in houses, ride in Studebaker wagons, send children to school, drink whiskey and own property."

Antonio Luhan described how government policies and the Bureau of Indian Affairs commissioners who enforced them overwhelmed American Indian culture,

“"We have got a real friend in John Collier. He really likes Indians. In past time, we had Commissioners against us who tried to stop our ceremony dances and our dances-religious. They nearly destroy us; call our ways bad or moral or something, and put in the paper they are going to stop us. But John Collier fight for us with the Indian Defense Association and he save us. Now, he look far ahead and it is like he is putting a wall all around us to protect us - and this Wheeler-Howard Bill is this wall. And no white man or grafter can come inside and take away our land or our religion which are connected together." 

Answer 2

The New England Confederation was formed to defend against Native Americans.
This confederation was formed back in 1643, and consisted of the following colonies: Massachusetts Bay, Plymouth, Connecticut, and New Haven. They banded together in order to defend themselves from Native Americans after a war between two tribes.
