The Pennsylvania Dutch (Pennsilfaanisch Deitsch, ) are a cultural group formed by early German-speaking immigrants to Pennsylvania and their descendants. This early wave of settlers, which would eventually coalesce to form the Pennsylvania Dutch, began in the late 17th century and concluded in the late 18th century. The majority of these immigrants originated in what is today southwestern Germany, i.e., Rhineland-Palatinate and Baden-Württemberg; other prominent groups were Alsatians, Dutch, French Huguenots (French Protestants), Moravians from Bohemia and Moravia, and Swiss.
