[5] Neither Wulfad's support for Pippin nor his defrocking by Hincmar deterred Charles the Bald from appointing him archbishop of Bourges in 866.
[5] He had probably supported the king during the Neustrian rebellions of 858–60, for in a charter of 859 Charles calls him "our dearest abbot and minister".
[6] Although Hincmar disputed Wulfad's eligibility for the episcopate,[5][7] the synod held at Soissons in August 866 refused to adjudicate the case.
[8] In 868 Charles convinced Pope Nicholas I that Wulfad's "prudence and vigour" were needed to counter the Vikings that threatened the region around Bourges.
A list of books in Wulfad's library, probably intended to circulate among his friends, has survived on the back of a manuscript copy of the philosopher John Scotus Eriugena's Ambigua.
