when did the first immigrants from germany arrived in america
German Americans None of the German states had American colonies. In the 1670s, the first significant groups of German immigrants arrived in the British colonies, settling primarily in Pennsylvania, New York, and Virginia. Immigration continued in very large numbers during the 19th century, with eight million arrivals from Germany. Between 1820 and 1870 over seven and a half million German immigrants came to the United Statesâ€”more than doubling the entire population of the country. By 2010, their population grew to 49.8 million immigrants, reflecting a jump of 6 million people since 2000.
