The Catholic Historical Society, which publishes Archivium Hibernicum  is affiliated to CIHEC.

The annual CIHEC meeting of 2013 will take place in Vilnius, Lithuania,
on 6-8 June. The theme of the conference is
‘Christian and the non-Christian other’.

CIHEC?s purpose is to facilitate contacts and exchanges of information between
historians of Christianity working in different countries. It does this
principally by organising international conferences.
