Вальдемар II
Innocent III declared Philip's marriage to Agnes null and void, as he was still married to Ingeborg. He ordered the King to part from Agnès; when he did not, the Pope placed France under an interdict in 1199. This continued until 7 September 1200. Needing an alliance from Ingeborg's brother, King Valdemar II of Denmark (1202–41), Philip finally allowed Ingeborg to be recognized as his Queen in 1213.
