Pope Adrian II inherited many of the complex political and theological challenges left by St. Nicholas I. Although already elderly when elected pope, Adrian guided the Church with humility, wisdom, and compassion during a pivotal period in relations between the Latin West and the Greek East.

His pontificate is chiefly remembered for approving the Fourth Council of Constantinople (AD 869-870), recognized by the Catholic Church as the Eighth Ecumenical Council, which condemned Photius and restored St. Ignatius of Constantinople as the legitimate patriarch.
