Breifne Historical Society has almost 400 members. Membership includes a free copy of the Annual Journal.
It was founded as a non political and non sectarian historical society to promote interest in and the study of the local history of the ancient kingdom of Breifne.
Breifne Historical Society hosts a series of lectures each year on various aspects of local and Irish history generally. It also organizes an annual tour to some place of historical interest. These tours normally take place in the summer months.
The society publishes a journal called ‘Breifne’ which is published in April or May of each year. The first journal was published in 1958 and forty three journals have been published since then. It is now recognized as one of the best and most reputable local history journals in Ireland.
