This charter, given to the Jewish community of Barcelona in 1241 by King James I, is preserved only as copied into a later grant to the Jewish community of Perpignan (Arxiu de la Corona d'Arago, reg. 16 fo. 158). This seems to have been the first formal involvement of the king in Jewish communal governance.

Let it be generally known that we James [I of Aragon] etc., concede to you the entire congregation of the Jews of Barcelona and give our license and permission that you may elect among you two or three honest and worthy men (prohoms) or more if you wish, according to your understanding, who shall diligently see and investigate those persons who should engage in any folly or say any harmful words to the other Jewish worthies (prohoms) on whom they shall have the power to impose penalties and fines, which we shall receive, and which in our place is to be given to our bailiff of Barcelona. By their own authority amongst you, they even may eject [them] either from your Call [the area of Jewish residence] or outside of Barcelona, according to how they should see fit to expel them. They also may judge cases between you of law, or suits and plaints [raised] by one Jew against another.
