Page "Absalon" Paragraph 9
Absalon reformed the Danish church organisation to closer match Holy See praxis, and worked to keep Denmark a close ally of the Holy See.
However, during the schism between Pope Alexander III and Antipope Victor IV, Absalon stayed loyal to Valdemar even as he joined the Holy Roman Emperor Frederick Barberossa in supporting Victor IV.
This caused a split within the Danish church, as it possibly forced Eskil into exile around 1161, despite Abaslon's attempts to keep the Danish church united.
It was contrary to Absalon's advice and warnings that Valdemar I rendered fealty to the emperor Frederick Barbarossa at Dole in 1162.
When Valdemar returned to Denmark, he was convinced into strengthening the Danevirke fortifications at the German border, with the support of Absalon.
