Amish
Many of the people who emigrated kept their language, which is a dialect of German and known as Pennsylvania German or Pennsylvania Dutch. In 2012, it was estimated that there were between 350.000 and 420.000 speakers of Pennsilvania German. Pennsylvania German was relatively common until the time before the Second World War, with an estimate of about 800.000 speakers. During the war, people frowned upon German speakers, so many speakers did not teach the language to their children. Only conservative Baptists, such as Amish and Mennonites withstood the pressure, and sill taught the language to their children.
