 Charlemagne was extremely conscious of the notions of succession and inheritance during his lifetime, even refusing to marry off his daughters to the Frankish nobility.This quirk scandalized later contemporary historians ("Strange to say," Einhard writes, "he never wanted to give any one of them in marriage to anybody") and probably reflects Charles' reluctance to leave problematic heirs that could interfere with a peaceful succession after his death.But in spite of all the potential difficulties that Pepin presented for the succession—particularly his dubious birth and problematic deformity—sources suggest that Charlemagne treated him with affection and even respect.
