1gyokm | How has it come to be that Americans speak English and not French, Spanish, Portuguese, Dutch etc.? | I'm not particularly well-informed on the early history of North America but I gather there were many colonies founded by people from many different parts of Europe. From this variety how did homogeneity come about, in language and government?
Thanks. | AskHistorians | http://www.reddit.com/r/AskHistorians/comments/1gyokm/how_has_it_come_to_be_that_americans_speak/ | {
