Charlemagne, for example, the most Christian monarch, had a large number of concubines and divorced a wife who did not please him; yet his biographer Einhard, pious monk as he was, has no word of censure for his monarch's irregularities; and policy prevented the Church from thundering at a king who so valiantly crushed the heretics, her enemies.

Einhard, Vita Kar.

Einhard, the son-in-law and historian of Charlemagne, records a partial defeat in the Pyrenees in 777-778, and adds that Hroudlandus was slain.
