In 1520, Freiburg decided not to take part in the Reformation and became an important centre for Catholicism on the Upper Rhine. Erasmus moved here after Basel accepted the Reformation. In 1536, a strong and persistent belief in witchcraft led to the city's first witch-hunt. The need to find a scapegoat for calamities such as the Black Plague, which claimed 2,000 area residents (25% of the city population) in 1564, led to an escalation in witch-hunting that reached its peak in 1599. A plaque on the old city wall marks the spot where burnings were carried out.
