Pope Formosus
The situation in Italy began to deteriorate with the election of a new pope, Formosus, in 891. Distrustful of Guy, he began to look elsewhere for support against the emperor, as Guy found it increasingly difficult to end the threat of Berengar who still held out in his Duchy of Friuli. To bolster his overall position, at Ravenna on 30 April 892, Guy forced Pope Formosus to crown Lambert as co-emperor.
