The tide of German immigration to Pennsylvania swelled between 1725 and 1775, with immigrants arriving as redemptioners or indentured servants. By 1775, Germans constituted about one-third of the population of the state. German farmers were renowned for their highly productive animal husbandry and agricultural practices. Politically, they were generally inactive until 1740, when they joined a Quaker -led coalition that took control of the legislature, which later supported the American Revolution . Despite this, many of the German settlers were loyalists during the Revolution, possibly because they feared their royal land grants would be taken away by a new republican government, or because of loyalty to a British German monarchy who had provided the opportunity to live in a liberal society.  The Germans, comprising Lutherans , Reformed , Mennonites , Amish , and other sects, developed a rich religious life with a strong musical culture. Collectively, they came to be known as the Pennsylvania Dutch (from Deutsch ).
