Why was New England geographically perfect for the development of factories in the 1800's? What event caused the beginning of American industry? what statistic tells how geographically lopsided American industry was by 1861 (beginning of civil war) ?

Because New England had much room for factories and not for farming which made it idealistic to use land for factories. American industry was bought from England and it started many jobs. I'd your talking about the southern part for farming geography then it was the beginning of the civil war because southerners needed worker for plantation and they didn't want to pay the workers, therefore they bought in African American slaves to do work. North did not approve of this and so this could be a reason the south could want to secede from the menorah for not allowing slavery
