The Hiberno-Scottish mission was a series of expeditions in the 6th and 7th centuries by Gaelic missionaries originating from Ireland that spread Celtic Christianity in Scotland, Wales, England and Merovingian France. Celtic Christianity spread first within Ireland. Since the 8th and 9th centuries, these early missions were called 'Celtic Christianity'.
