After the death of Dagobert (638), Gaule is divided in two parts, Austrasie and Neustrie, and Mérovingiens become in spite of them "lazy kings", i.e.
they are reduced to the impotence, not by their idleness, but by the refusal to obey of the frank warriors, who do not want to be treated in subjects.
The capacity passes to the mayor of the palate, species of Prime Minister, who, in Neustrie, remains devoted with the king, but who, in Austrasie, is the chief of his enemies.
That of Neustrie, Ebroïn, which undertakes to raise the royalty, perishes assassinated (681), and the last partisans of the royal authority are overcome in Testry by Pépin of Héristal, mayor of the palate of Austrasie (687).
His son, Charles Martel (715-741), subjects Neustrie definitively, and stops in Poitiers the invasion of the Arabs (732); it misses only the title of king.
Pépin the Brief (741-768), son of Charles Martel, is linked narrowly with the Church: thanks to Pépin, the pope is delivered of Lombards; thanks to the pope, Pépin is crowned king.
Mérovingiens make place with the Carolingians.
