The database is a breakthrough revision in a digitized format of Reinhold Röhricht’s original Regesta regni Hierosolymitani  (1893-1904). The 2016 Revised Regesta offers an expanded and corrected calendar of all the charters, other legal or formal documents and letters and inscriptions originating  in the Latin East between 1098 and 1291.

All charters are rendered in English, in the hope that it will be useful to university teachers who want to introduce students to this extremely valuable range of medieval sources.

This immense project was initiated by professor Jonathan Riley-Smith  of Cambridge University.  It is carried on by Professor Riley-Smith  in collaboration of an international  scientific committee of crusades scholars  

A ceremonial launching of the database took place at Cambridge University on August 15, 2016.  Professor Riley-Smith, Professor Benjamin Z. Kedar, Professor Ronnie Ellenblum, and many others were in attendance.
