The historiography has for long time ignored the resignation of the Civilian General Commissioner for the Julian March Augusto Ciuffelli, who left his office after four months only at the beginning of December 1919. The archival research proves that the reason of his resignation was his decision to cancel the religious teaching in public schools, break-ing the Austrian law still in force. The reaction of the population shows its loyalty to the Habsburg heritage, even when supporting the union to Italy.
