 In 1369, Philadelphia replaced Sardis as the see of the metropolitan bishop, Sardis having been suppressed by the Patriarch of Constantinople.However, a bearer of the title of Metropolitan of Sardis, Dionysius, participated in the Council of Florence in 1438, but died before its conclusion and thus was not asked to sign its decree.From the 17th century, there were appointments of Roman Catholic archbishops of Sardis as a see "in partibus infidelium", meaning "within territory held by the infidels" (the Muslims), a term replaced in 1882 by that of "titular see".
