It is said that on October 31, 1517, Martin Luther nailed his 95 theses to the door of the castle church in Wittenberg, thereby setting off the Protestant Reformation.
Väidetavasti naelutas Martin Luther oma 95 teesi 1517. aastal just 31. oktoobril Wittenbergi lossikiriku uksele, pannes nii aluse protestantlikule usupuhastusele.
