In the 7th and 8th centuries came Christianization by Irish-Scottish and Anglo-Saxon monks (Pirmin, Boniface). On the muschelkalk lands of today's Bauland, which favoured agriculture, a broad mesh of settlements arose. The parts of the Odenwald farther in from the rivers, though, with their scant New Red Sandstone soils remained uninhabited. Four Benedictine monasteries were assigned the job of opening the empty woods up by the central Frankish power (Carolingian), Lorsch Abbey from the west, Fulda Monastery from the east and Mosbach Monastery from the south. Amorbach Monastery had the greatest importance for ecclesiastical, cultural and economic development in the eastern Odenwald.
