Immigration into America was not limited to English speakers, though. In the second half of the 19th Century, in particular, over 30 million poured into the country from all parts of the world. At the peak of immigration, from 1901 to 1905, America absorbed a million Italians, a million Austro-Hungarians, half a million Russians and tens of thousands each from many other countries. Many nationalities established their own centres: the Amish or Pennsylvania Dutch (actually Germans, as in Deutsch) tended to stay in their isolated communities, and developed a distinctive English with a strong German accent and an idiosyncratic syntax; many Germans also settled in Wisconsin and Indiana; Norwegians settled in Minnesota and the Dakotas; Swedes in Nebraska; etc.
