Battle of the Boarn: The Franks under Charles Martel, mayor of the palace of Neustria and Austrasia, defeat the Frisians near the mouth of the River Boarn (now the Dutch province of Friesland). During the battle, the Frisian army is beaten and King Poppo is killed.[1] The Franks gain control of the Frisian lands west of the Lauwers (Netherlands), and begin plundering the pagan sanctuaries. The Frisians become Frankish vassals, apart from the tribes living in East Frisia in present-day Germany.
