This four-volume collection covers the church history of the islands of Great Britain and Ireland from AD 200 to 1295, which spans from the Roman period to the Anglo-Saxon period. The collection is based upon the monumental Concilia Magnae Britanniae et Hiberniae written by David Wilkins, plus other sources that had arisen since its publication in 1737. Editors Arthur Haddon and William Stubbs arranged the documents in chronological order by each period and by national or local branches of the churches in Great Britain and Ireland. The documents cover the divisions and combinations of the churches, present letters and decrees, and include the memorials of Saint Patrick. This collection is ideal for those who are interested in the history of the church in the British and Irish islands.
