Louis renounces his agreement by a treaty signed at Coblenz on June 7, 860, under which Charles promises Alsace to Louis.

Lothair II had named as his successor his Welf son-in-law, Henry the Proud, Duke of Bavaria, before dying on December 4, 1137.

The princes, ignoring this bequest, gather at Coblenz and elect Lothair’s former rival Conrad, whose assumption of the German kingship as Conrad III inaugurates Hohenstaufen dynasty rule.

One of Conrad’s first acts is to deprive Henry the Proud of his lands in July 1138 and award them to the Margrave Leopold IV of Austria.

The fires have also been rekindled in the three prince-archbishoprics of the Rhineland.

Twenty-four witches are burnt in 1629 at Coblenz, the seat of the Prince-Archbishop of Trier.
