The effects were huge and long-lasting. Even today, Europeans' exploration and colonization of the world is still felt. Effects included the spread of disease; exchange of crops, crafts, ideas, etc.; religious conversions; forced removal of Native American tribes from their land; warfare; new economic trade routes; and the growth of new cultures and merging of old ones. Even today, the effects of colonialism are still felt, such as seen in debates on whether Columbus was a 'good' man or whether his ambitions and realities are responsible for the continued poverty and socio-economic issues of Native peoples. I highly recommend a visit to the National Museum of the American Indian in Washington, D.C., which has several galleries that explore native cultures and the impacts that colonization have had on them.
