Henry IV (German: Heinrich IV; 11 November 1050 – 7 August 1106) was Holy Roman Emperor from 1084 to 1105. The Jews of Speyer approached him  for the confirmation of their rights that had been granted by Bishop Rüdiger Huzmann. He summarized their liberties in a diploma, protecting them against physical assaults and prohibiting their forced baptism. He issued a similar document for the Jews of Worms.
