The Franks embraced the Christian Gallo-Roman culture and ancient Gaul was eventually renamed "Francia" ("Land of the Franks"). The Germanic Franks adopted Romanic languages, except in northern Gaul where Roman settlements were less dense and where Germanic languages emerged. Clovis made Paris his capital and established the Merovingian dynasty, but his kingdom would not survive his death. The Franks treated land purely as a private possession and divided it among their heirs, so four kingdoms emerged from Clovis's: Paris, Orléans, Soissons, and Rheims. The last Merovingian kings lost power to their mayors of the palace (head of household). One mayor of the palace, Charles Martel, defeated an Islamic invasion of Gaul at the Battle of Tours (732) and earned respect and power within the Frankish kingdoms. His son, Pepin the Short, seized the crown of Francia from the weakened Merovingians and founded the Carolingian dynasty. Pepin's son, Charlemagne, reunited the Frankish kingdoms and built a vast empire across Western and Central Europe.
