“Agreement between King Adolph and Archbishop Gerhard of Mainz” [Germany]: “[…]: 1. Any profit that the Archbishop will make from his case against the citizens and Jews of Mainz […] will be split, and then equally divided between Adolf and Gerhard for two years. After that the Jews will belong entirely to the Archbishop.”
