Originally, the economy of the region was almost entirely rural and agricultural, based on the immigrants' dream of bettering their lot through the ownership of their own farms. The small tradesmen indispensable to a rural economy, such as blacksmiths, wheelwrights, millers, and storekeepers, constituted the bulk of the non-farm economy. In the 19th century, a small educated class, comprising the Lutheran and Reformed ministers, began to emerge. The Pennsylvania seminaries educated them in High German so that they could preach to their flocks in a scholarly way.
