U.S. History/helppp


what are three reasons that the u.s expansion i the 1800's was both unjustifiable and justifible i witing an essay and i really need help on the plot of my essay too answer quckly

I suppose three reasons it was unjustifiable was that it took land away from native Americans who had the most just claim to the land, it resulted in war with this neighbor Mexico, and it eventually drew the US into additional wars as a world power.  One could also see it as justifiable because it provided land and opportunity for Americans as well as immigrants.  It prevented European powers from establishing more control over the Continent.  It also allowed the US to develop into a superpower that has been a force for democracy and freedom.

I can answer just about any question on early American History. My specialties are the American Revolution through the Civil War/Reconstruction. I also have greater expertise in matters relating to military, political or legal history.


I have lectured at George Washington University regarding the Civil War, as well as several elementary school Civil War demonstrations. I was also a member of a Civil War reenactment group for about 10 years.
