The League of the Rhine (also known as the Erste Rheinbund, First Rhine-Bund; or the Rheinische Allianz - Rhenish Alliance) was a defensive union of more than 50 German princes and their cities along the River Rhine, formed on 14 August 1658 by Louis XIV of France and negotiated by Cardinal Mazarin (then de facto prime minister of France), Hugues de Lionne and Johann Philipp von Schönborn (Elector of Mainz and Chancellor of the Empire).



Its intended aim was to weaken the position of the Holy Roman Emperor (at that time, Ferdinand III) and to marginalise the Austrian House of Habsburg. Louis XIV had wished to be elected Emperor himself, but had failed, despite the French victory at the Battle of the Dunes. The new confederation allied itself to France, swearing not to let any anti-French troops (marching to attack France in the Spanish Netherlands or elsewhere) pass through their territory, thus protecting France's eastern frontier with a "military border" running along the Rhine and cutting Austria off from the Spanish Netherlands. Sweden was guaranteed its German possessions in Bremen-Verden, and later also those in Swedish Pomerania. The League's members also swore to maintain the clauses of the 1648 Treaty of Westphalia, the treaty which had made the League possible by authorising the German princes, immediate vassals of the Emperor, to conclude alliances between themselves or with foreign states.

Life and afterlife

On August 14, 1658, the League of the Rhine was formed by:

  • Karl Kaspar von der Leyen, Prince Elector of Trier
  • Johann Philipp von Schönborn, Prince Elector of Mainz
  • Maximilian Henry, Prince Elector of Cologne
  • Bernhard von Galen, bishop of Münster
  • Charles I Louis, Elector Palatine of the Rhine
  • Ferdinand Maria, duke of Bavaria
  • Wilhelm VI, landgrave of Hesse-Kassel (or Hesse-Cassel)
  • Augustus the Younger, duke of Brunswick
  • Philip IV of Spain, in his title of duke of Luxembourg
  • Charles X, king of Sweden
  • The League fielded a force of 6000 to fight on the side of France and the Empire against the Ottomans, seeing action in the 1664 Battle of Saint Gotthard.

    The League was promulgated to last for three years, and this was later twice extended. It officially ended in August 1667, its end should in fact be dated to 1668, since French diplomacy succeeded in negotiating a further extension of the alliance as the Rheinbundrat, made up only of the main members of the League, which lasted to 1688. The League was later resurrected by Napoleon as the Confederation of the Rhine, which gave the final death-blow to the Holy Roman Empire.
