W.N. Osborough was described by the Irish Times on his death in 2020 as Ireland's ' greatest legal historian' . He wrote prolifically on Irish legal history and culture for over fifty years, re-established legal history as an undergraduate option in university law degrees and was the moving force behind the establishment of the Irish Legal History Society in 1988. Throughout this volume the authors uncover new insights into the evolution and practice of law in Britain and Ireland and honour Nial's impressively wide-ranging interests, which spanned traditional periodizations and geographical divides.
