Many of the witch-trials of the 1620s multiplied with the Catholic reconquest. In some areas the lord or bishop was the instigator, in others the Jesuits. Sometimes local witch-committees were set up to further the work. Among prince-bishops, Philipp Adolf von Ehrenberg of Würzburg was particularly active: in his reign of eight years (1623–31) he burnt 900 persons, including his own nephew, nineteen Catholic priests, and children of seven who were said to have had intercourse with demons. The years 1627–29 were dreadful years in Baden, recently reconquered for Catholicism by Tilly: there were 70 victims in Ortenau, 79 in Offenburg. In Eichstätt, a Bavarian prince-bishopric, a judge claimed the death of 274 witches in 1629. At Reichertshofen, in the district of Neuburg an der Donau, 50 were executed between November 1628 and August 1630. In the three prince-archbishoprics of the Rhineland the fires were also relit. At Coblenz, the seat of the Prince-Archbishop of Trier, 24 witches were burnt in 1629; at Sélestat at least 30—the beginning of a five-year persecution. In Mainz, too, the burnings were renewed. At Cologne the City Fathers had always been merciful, much to the annoyance of the prince-archbishop, but in 1627 he was able to put pressure on the city and it gave in. Naturally enough, the persecution raged most violently in Bonn, his own capital. There the chancellor and his wife and the archbishop's secretary's wife were executed, children of three and four years were accused of having devils for their paramours, and students and small boys of noble birth were sent to the bonfire.
