How many of you did not know about Germans as the largest ethnic group? And here's a quote from another site (
http://www.ushistory.org/us/25f.asp) that states the following:
"In the decade from 1845 to 1855, more than a million Germans fled to the United States to escape economic hardship. They also sought to escape the political unrest caused by riots, rebellion and eventually a revolution in 1848. The Germans had little choice — few other places besides the United States allowed German immigration. Unlike the Irish, many Germans had enough money to journey to the Midwest in search of farmland and work. The largest settlements of Germans were in New York City, Baltimore, Cincinnati, St. Louis and Milwaukee.
With the vast numbers of German and Irish coming to America, hostility to them erupted. Part of the reason for the opposition was religious. All of the Irish and many of the Germans were Roman Catholic. Part of the opposition was political. Most immigrants living in cities became Democrats because the party focused on the needs of commoners. Part of the opposition occurred because Americans in low-paying jobs were threatened and sometimes replaced by groups willing to work for almost nothing in order to survive."
Sounds very familiar to me these days.
