Pennsylvania Dutch Country refers to an area of southeastern Pennsylvania that by the American Revolution ha a high percentage of Lutheran, German Reformed, Moravian, Amish, Mennonite and other German sectarian inhabitants and where the Deitsch language was historically common. The term was used in the middle of the 20th century as a description of a region with a distinctive Pennsylvania Dutch culture, but in recent decades the composition of the population is changing and the phrase is used more now in a tourism context than any other.
