What effects did the three worlds colliding have on development in north america? (time period 1)

the collision of the cultures brought about a radical idea that no country before had ever effectively put into practice: the idea that nationality and citizenship does not need to be based on race. the different cultures brought their gifts and talents into the new world, enabling incredible leaps in science, human rights and medicine, even after a couple rocky starts.

america expanded into the greatest nation on earth after fighting the bloodiest war in its history for the rights of african americans, gaining rights for women and pursuing life, liberty and happiness through its radical belief that "all men are created equal", whether black or white, native american or any other race.

a.) d-day invasion of normandy.
