The Pennsylvania Dutch (Pennsylvania German: Pennsilfaanisch-Deitsch), also referred to as the Pennsylvania Germans, are a cultural group formed by German immigrants settling in the state of Pennsylvania during the 18th and 19th centuries. These emigrated primarily from German-speaking territories of Europe, now partly within modern-day Germany (mainly from Palatinate, Baden-Württemberg, Hesse, and Rhineland), but also from the Netherlands, Switzerland and Alsace-Lorraine (then part of Germany), traveling down the Rhine river to seaports.
The first settlers described themselves as Deitsch, corresponding with the German language Deutsch (for "German") later corrupted to "Dutch". They spoke numerous south German dialects, including Palatine. It was through their cross-dialogue interaction, the relative lack of new German immigrants from about 1770 to 1820, and what was retained by subsequent generations that a hybrid dialect emerged, known as Pennsylvania German (or Pennsylvania Dutch), which has resonance to this day.
The Pennsylvania Dutch maintained numerous religious affiliations, with the greatest number being Lutheran or German Reformed, but also many Anabaptists, including Mennonites, Amish, and Brethren. The Anabaptist groups espoused a simple lifestyle, and their adherents were known as Plain people (or Plain Dutch); this contrasted to the Fancy Dutch, who tended to assimilate more easily into the European American mainstream. By the late 1700s, other denominations were also represented in smaller numbers.
Contrary to popular belief, the word "Dutch" in "Pennsylvania Dutch" is not a mistranslation, but rather a corruption of the Pennsylvania German endonym Deitsch, which means "Pennsylvania Dutch / German" or "German". Ultimately, the terms Deitsch, Dutch, Diets and Deutsch are all descendants of the Proto-Germanic word *þiudiskaz meaning "popular" or "of the people". The continued use of "Pennsylvania Dutch" was strengthened by the Pennsylvania Dutch in the 19th century as a way of distinguishing themselves from later (post 1830) waves of German immigrants to the United States, with the Pennsylvania Dutch referring to themselves as Deitsche and to Germans as Deitschlenner (literally "Germany-ers", compare Deutschland-er) whom they saw as a related but distinct group.
After the Second World War, use of Pennsylvania German virtually died out in favor of English, except among the more insular and tradition-bound Anabaptists, such as the Old Order Amish and Old Order Mennonites. A number of German cultural practices continue to this day, and German Americans remain the largest ancestry group claimed in Pennsylvania by people in the census.
The Pennsylvania Dutch live primarily in Southeastern and in Pennsylvania Dutch Country, a large area that includes South Central Pennsylvania, in the area stretching in an arc from Bethlehem and Allentown through Reading, Lebanon, and Lancaster to York and Chambersburg. Some Pennsylvania Dutch live in the historically Pennsylvania Dutch-speaking areas of Maryland, North Carolina, and Virginia's Shenandoah Valley.
Many Pennsylvania Dutch were descendants of refugees who had left religious persecution in the Netherlands and the Palatinate of the German Rhine. Of note were Amish and Mennonites who came to the Palatinate and surrounding areas from the German-speaking part of Switzerland, where, as Anabaptists, they were persecuted, and so their stay in the Palatinate was of limited duration.
Most of the Pennsylvania Dutch have roots going much further back in the Palatinate. During the War of the Grand Alliance (1689-97), French troops pillaged the Palatinate, forcing many Germans to flee. The war began in 1688 as Louis XIV laid claim to the Electorate of the Palatinate. French forces devastated all major cities of the region, including Cologne. By 1697 the war came to a close with the Treaty of Ryswick, now Rijswijk in the Netherlands, and the Palatinate remained free of French control. However, by 1702, the War of the Spanish Succession began, lasting until 1713. French expansionism forced many Palatines to flee as refugees.
The devastation of the Thirty Years' War (1618-1648) and the wars between the German principalities and France caused some of the immigration of Germans to America from the Rhine area. Members of this group founded the borough of Germantown, in northwest Philadelphia County, Pennsylvania, in 1683. They settled on land sold to them by William Penn. Germantown included not only Mennonites but also Quakers.
This group of Mennonites was organized by Francis Daniel Pastorius, an agent for a land purchasing company based in Frankfurt am Main. None of the Frankfurt Company ever came to Pennsylvania except Pastorius himself, but 13 Krefeld German (South Guelderish-speaking) Mennonite families arrived on October 6, 1683, in Philadelphia. They were joined by eight more Dutch-speaking families from Hamburg-Altona in 1700 and five German-speaking families from the Palatinate in 1707.
In 1723, some 33 German Palatine families, dissatisfied under Governor Hunter's rule, migrated from Schoharie, New York, along the Susquehanna River to Tulpehocken, Berks County, Pennsylvania, where other Palatines had settled. They became farmers and used intensive German farming techniques that proved highly productive.
Another wave of settlers from Germany, which would eventually coalesce to form a large part of the Pennsylvania Dutch, arrived between 1727 and 1775; some 65,000 Germans landed in Philadelphia in that era and others landed at other ports. Another wave from Germany arrived 1749-1754. Not all were Mennonites; some were Brethren or Quakers, for example. The majority 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 Germans from Switzerland. 
The Pennsylvania Dutch composed nearly half of the population of Pennsylvania and, except for the nonviolent Anabaptists, generally supported the Patriot cause in the American Revolution. Henry Miller, an immigrant from Germany of Swiss ancestry, published an early German translation of the Declaration of Independence (1776) in his newspaper Philadelphische Staatsbote. Miller often wrote about Swiss history and myth, such as the William Tell legend, to provide a context for patriot support in the conflict with Britain.
Frederick Muhlenberg (1750-1801), a Lutheran pastor, became a major patriot and politician, rising to be elected as Speaker of the U.S. House of Representatives.
An early group, mainly from the Roxborough-Germantown area of Pennsylvania, emigrated to then colonial Nova Scotia in 1766 and founded the Township of Monckton, site of present day Moncton, New Brunswick. The extensive Steeves clan descends from this group.
After the American Revolution, John Graves Simcoe, Lieutenant Governor of Upper Canada, invited Americans, including Mennonites and German Baptist Brethren, to settle in British North American territory and offered tracts of land to immigrant groups. This resulted in communities of Pennsylvania Dutch speakers emigrating to Canada, many to the area called the German Company Tract, a subset of land within the Haldimand Tract, in the Township of Waterloo, which later became Waterloo County, Ontario. Some still live in the area around Markham, Ontario and particularly in the northern areas of the current Waterloo Region. Some members of the two communities formed the Markham-Waterloo Mennonite Conference. Today, the Pennsylvania Dutch language is mostly spoken by Old Order Mennonites.
From 1800 to the 1830s, some Pennsylvania Dutch Mennonites in Upstate New York and Pennsylvania moved north to Canada, primarily to the area that would become Cambridge, Ontario, Kitchener, Ontario/Waterloo, Ontario and St. Jacobs, Ontario/Elmira, Ontario/Listowel, Ontario in Waterloo County, Ontario. Settlement started in 1800 by Joseph Schoerg and Samuel Betzner, Jr. (brothers-in-law), Mennonites, from Franklin County, Pennsylvania. Other settlers followed mostly from Pennsylvania typically by Conestoga wagons. Many of the pioneers arriving from Pennsylvania after November 1803 bought land in a 60,000 acre section established by a group of Mennonites from Lancaster County Pennsylvania, called the German Company Lands.
Fewer of the Pennsylvania Dutch settled in what would later become the Greater Toronto Area in areas that would later be the towns of Altona, Ontario, Pickering, Ontario and especially Markham Village, Ontario and Stouffville, Ontario. Peter Reesor and brother-in-law Abraham Stouffer were higher profile settlers in Markham and Stouffville.
William Berczy, a German entrepreneur and artist, had settled in upstate New York and in May 1794, he was able to obtain 64,000 acres in Markham Township, near the current city of Toronto. Berczy arrived with approximately 190 German families from Pennsylvania and settled here. Others later moved to other locations in the general area, including a hamlet they founded, German Mills, Ontario, named for its grist mill; that community is now called Thornhill, Ontario), in the township that is now part of York Region.
The immigrants of the 1600s and 1700s who were known as the Pennsylvania Dutch included Mennonites, Swiss Brethren (also called Mennonites by the locals) and Amish but also Anabaptist-Pietists such as German Baptist Brethren and those who belonged to German Lutheran or German Reformed Church congregations. Other settlers of that era were of the Moravian Church while a few were Seventh Day Baptists. Calvinist Palatines and several other denominations were also represented to a lesser extent.
Over 60% of the immigrants who arrived in Pennsylvania from Germany or Switzerland in the 1700s and 1800s were Lutherans and they maintained good relations with those of the German Reformed Church. The two groups founded Franklin College (now Franklin & Marshall College) in 1787.
Henry Muhlenberg (1711-1787) founded the Lutheran Church in America. He organized the Ministerium of Pennsylvania in 1748, set out the standard organizational format for new churches and helped shape Lutheran liturgy.
Muhlenberg was sent by the Lutheran bishops in Germany, and he always insisted on strict conformity to Lutheran dogma. Muhlenberg's view of church unity was in direct opposition to Nicolaus Ludwig Zinzendorf's Moravian approach, with its goal of uniting various Pennsylvania German religious groups under a less rigid "Congregation of God in the Spirit". The differences between the two approaches led to permanent impasse between Lutherans and Moravians, especially after a December 1742 meeting in Philadelphia. The Moravians settled Bethlehem and nearby areas and established schools for Native Americans.
