The great German immigration begins to flow in earnest in this period. Three successive tides of migration have set from Germany to America. The first was the movement of the petty sects under the invitation and patronage of William Penn, quartering themselves in the eastern parts of Pennsylvania. The second was the transportation of "the Palatines," expatriated by stress of persecution and war, not from the Rhenish Palatinate only, but from the archduchy of Salzburg and from other parts of Germany and Switzerland, gathered up and removed to America, some of them directly, some by way of England, as an act of political charity by Queen Anne's government, with the idea of strengthening the colonies by planting Protestant settlers for a safeguard against Spanish or French aggressions. The third tide continues flowing, with variable volume, to this day. It is the voluntary flow of companies of individual emigrants seeking to better the fortunes of themselves or their families. But this voluntary migration has been unhealthily and sometimes dishonestly stimulated, from the beginning of it, by the selfish interests of those concerned in the business of transportation or in the sale of land. It seems to have been mainly the greed of shipping merchants, at first, that spread abroad in the German states florid announcements of the charms and riches of America, decoying multitudes of ignorant persons to risk everything on these representations, and to mortgage themselves into a term of slavery until they should have paid the cost of their passage by their labor. This class of bondmen, called "redemptioners," made no inconsiderable part of the population of the middle colonies; and it seems to have been a worthy part. The trade of "trepanning" the unfortunates and transporting them and selling their term of service was not by several degrees as bad as the African slave-trade; but it was of the same sort, and the deadly horrors of its "middle passage" were hardly less.
In one way and another the German immigration had grown by the middle of the eighteenth century to great dimensions. In the year 1749 twelve thousand Germans landed at the port of Philadelphia. In general they were as sheep having no shepherd. Their deplorable religious condition was owing less to poverty than to diversity of sects.[188:1] In many places the number of sects rendered concerted action impossible, and the people remained destitute of religious instruction.
