 Political development did not always proceed harmoniously.Heavy setbacks came with the Thirty Years' War, by whose end Gumbsweiler had become uninhabited and uninhabitable, although the little late mediaeval church was left mostly unscathed.After the recovery, the Nine Years' War (known in Germany as the "Pfälzischer Erbfolgekrieg", or War of the Palatine Succession) brought further setbacks, and only in the 18th century did steady population growth begin.
