What was one reason that native americans began to negotiate with u. s. government about treaties that eventually led to the trail of tears?

Well, one obvious one is they didn't want to be forced out of their homeland, so they tried to make deals with the government to prevent that.

France played a key role in the american revolutionary war (american war of independence; 1775–1783). motivated by the ideals of the new nation which were inspired by the french enlightenment, as well as its long-term rivalry with britain and so as to avenge their territorial losses during the french and indian war, france secretly began sending supplies to the americans in 1775.
