In 1578, Count Palatine John Casimir founded the Neustadt College that was named after him, the Casimirianum, because his Lutheran brother, Louis had cleared the university in Heidelberg of Calvinists; John Casimir was active as an advocate of the reformed faith and offered the exiled professors and students asylum. When he moved to Heidelberg in 1583 in order to take over the regency for his still under-age son there after the death of the brother's reign, Neustadt's short time as a university seat ended.
