Protestantism had survived clandestinely among the mountain peasantry of the prince-archbishopric of Salzburg long after the Counter-Reformation. After Protestant villagers organised and appealed to the Corpus Evangelicorum, Archbishop Firmian issued an emigration patent in October 1731 requiring unpropertied Protestants to leave within eight days and property-holders within one to three months, in midwinter and in breach, the Protestant powers argued, of the Peace of Westphalia. Around 20,000 left. Frederick William I of Prussia offered them land in the depopulated Gumbinnen district of East Prussia and organised their transport; most of the emigrants walked north across Germany in publicised columns that became a European media event, and a small party was settled at Ebenezer in Georgia. Children below a certain age were initially retained by the Salzburg authorities to be raised Catholic, and their release was a principal demand of the Protestant states negotiating on the emigrants' behalf.
Prince-Archbishop Leopold Anton von Firmian expelled the Protestant peasantry of the archbishopric of Salzburg; Prussia and other Protestant states organised their reception
The archbishopric held roughly 190,000-200,000 people in the early eighteenth century. About 20,000 crypto-Protestants, drawn overwhelmingly from the Pongau, Pinzgau and Lungau valleys, were expelled under the emigration edict of 1731; most were resettled in East Prussia.
There was no mass killing. Deaths occurred among the very young and old on the winter march north and on the Atlantic passage to Georgia, and are recorded individually in the Prussian settlement registers and the Ebenezer records rather than as a total.
The stripping of residence rights from a subject population on grounds of confession, and the retention of emigrants' children by the Salzburg authorities for Catholic upbringing, are recorded in the emigration patent and in the diplomatic correspondence of the Corpus Evangelicorum, and are treated in Mack Walker's study of the expulsion.
