Welcome to CegeSoma (State Archives)

Who are we? CegeSoma is the fourth operational direction of the State Archives and the Belgian centre of expertise for the history of 20th century conflicts. We conduct fundamental historical research, develop public history projects, conserve archives and documentation and are engaged in societal debate.

Resistance in Belgium: national database on the Resistance in Belgium.

Since 21 October 2024 , the Resistance in Belgium platform allows anyone to research the Resistance in Belgium, thanks to a pilot project developed by CegeSoma/ State Archives . Given the growing interest in the history of the Resistance, it is essential today to make this information accessible to as many people as possible, and to enable everyone to carry out research on the subject.
