The power struggle that broke out between the Senate and the Citizens‘ Council of the city at the end of 17th century could, it was hoped, be resolved with the help of a revised constitution that would restore political stability. The Imperial Decree for Jews of 1710, the Judenreglement, became a legal component of the new city constitution, the Basic Law [so-called Hauptrezess] of 1712. In the State Archive Hamburg, the text is not preserved in its original form but rather as a twenty-page parchment document, the confirmation of the Regulations by Emperor Charles VI, dating from July 17, 1717. His late brother, Emperor Joseph I (d. 1711), had issued the Decree for Jews on September 17, 1710 as a reordering of the legal status of Jews and as part of an intended revision of the Hamburg constitution.
