influence over the others. The influence of the Arnulfing clan of Austrasia ensured that the political centre of gravity in the kingdom gradually shifted eastwards to the Rhineland. The Frankish realm was reunited in 613 by Chlothar II, the son of Chilperic, who granted his nobles the Edict of Paris in an effort to reduce corruption and reassert his authority. Following the military successes of his son and successor Dagobert I, royal authority rapidly declined under a series of kings, traditionally known as les rois fainéants. After the Battle of Tertry in 687, each mayor of the palace, who had formerly been the king's chief household official, effectively held power until in 751, with the approval of the Pope and the nobility, Pepin the Short deposed the last Merovingian king Childeric III and had himself crowned. This inaugurated a new dynasty, the Carolingians. Carolingian empire (751–843) The unification achieved by the Merovingians ensured the continuation of what has become known as the Carolingian Renaissance. The Carolingian Empire was beset by internecine warfare, but the combination of Frankish rule and Roman Christianity ensured that it was fundamentally united. Frankish government and culture depended very much upon each ruler and his aims and so each region of the empire developed differently. Although a ruler's aims depended upon the political alliances of his family, the leading families of Francia shared the same basic beliefs and ideas of government, which had both Roman and Germanic roots. The Frankish state consolidated its hold over the majority of western Europe by the end of the 8th century, developing into the Carolingian Empire. With the coronation of their ruler Charlemagne as Holy Roman Emperor by Pope Leo III in 800 AD, he and his successors were recognised as legitimate successors to the emperors of the Western Roman Empire. As such, the Carolingian Empire gradually came to be seen in the West as a continuation of the ancient Roman Empire. This empire would give rise to several successor states, including France, the Holy Roman Empire and Burgundy, though the Frankish identity remained most closely identified with France. After the death of Charlemagne, his only adult surviving son became Emperor and King Louis the Pious. Following Louis the Pious's death, however, according to Frankish culture and law that demanded equality among all living male adult heirs, the Frankish Empire was now split between Louis' three sons.
