What factors solidarity develop among american indians?

The factors that helped develop solidarity among the American Indians were the defense of indigenous territory and the need for survival.

Explanation:

The American Indians were robbed, plundered and tortured by the European man who coveted their lands for their riches and their freedom. We know that the American continent was built on the basis of the robbery and exploitation of native peoples, who suffered a lot from the colonization process and were often enslaved (as almost happened in Latin America).

All this exploitation created a concept of solidarity among the indigenous people, they knew that it would be very difficult to fight against the Europeans and for this reason decided to unite to defend their territory and to survive the violet invasion of the white man.

in february 1787, congress decided that a convention should be convened to revise the articles of confederation, the nation’s first constitution. in may, 55 delegates came to philadelphia, and the constitutional convention began. debates erupted over representation in congress, over slavery, and over the new executive branch. the debates continued through four hot and muggy months. but eventually the delegates reached compromises, and on september 17, they produced the u.s. constitution, replacing the articles with the governing document that has functioned effectively for more than 200 years.
