After learning more about the dramatic changes that occurred in the early 1800s, what methods of resolving conflict proved to be the most effective? Write your answer in one complete paragraph.
I really need help on this question because I have no idea what to write. I know that one way they resolved conflicts was with treaties, like in the Mexican-American War, but this wasn't effective because government officials did not abide by the treaty created at the end of this war. Can someone give me ideas on what to write please
