Basilinopolis

It was a suffragan of the Metropolis of Nicomedia, in the sway of the Patriarchate of Constantinople. At the Council of Chalcedon (451), the Metropolitans of Nicomedia and Nicaea were in sharp dispute about jurisdiction over the see of Basilinopolis. The council decided to assign it as a suffragan of Nicomedia. It was still reckoned as such in 1170 under Byzantine emperor Manuel Comnenus. The see does not figure in a Notitia episcopatuum of the Ecumenical Patriarchate of Constantinople after the 15th century, probably indicating that the city was destroyed in the Osmanli conquest. Historically documented bishops were: • Alexander, first known bishop, was consecrated by John Chrysostom about 400. • Gerontius (451) partook in the synod of Constantinople in 448 which condemned archimandrite Eutyches and the council of Chalcedon in 451. • Cyriacus (518) signed the letter after the synod of Constantinople in 518. • Sisinnius (680) attended the Third Council of Constantinople in 680 and the council in Trullo in 692. • Georgius (787) was at the Council of Nicaea in 787. • Anthimus (878) partook in the Council of Constantinople which rehabilitated the Patriarch Photius of Constantinople in 879–880. • archaeological finds mention bishop Michael, known from an 11th-century episcopal seal. == Catholic titular see ==
