The tradition of the world famous Oberammergau Passion Play began with an oath taken during the Thirty Year War.
At the time of the Swedish invasion Bavaria was ravaged by the plague, which cost more than 80 citizens of Oberammergau their lives.
In 1633, in the hope of acquiring God's help, the Oberammergau councilors swore an oath to perform the Tragedy of the Passion every 10 years if the village would be freed from the plague. The epidemic ceased and in 1634 the Oberammergauers honoured their pledge for the first time. In 1680 the play was rescheduled to be performed at the begin of each decade.
