Greek coins have been discovered which write the city name as Mlaundus. A Greek inscription of the Roman period though write the city Blaundus. Probably it is also the Blaeandrus that the Ptolemy is mentioning.
In the Roman and Byzantine eras, the city was the seat of a bishopric, a suffragan of the Metropolitan Archdiocese of Sardes. The diocese was known by the names Blaundus, Blandus and Balandus. It was part of the Patriarchate of Constantinople. In the 5th century AD, the bishopric was connected to the diocese center at Sebaste.
- Phoebus (fl. 359), who at the Council of Seleucia in 359 distanced himself from his fellow Arians, signing the orthodox formula drafted by Acacio of Caesarea, and for this reason was deposed.
- Elijah or Helias (fl. 451) who took part in the Council of Chalcedon of 451.
- Onesiphorus (fl. 458), who signed a letter written by the bishops of Lydia to Emperor Leo in 458 following the killing of Proterius of Alexandria.
Additionally, a certain Eustathius of Alandos attended the Council of Constantinople (879-880) that rehabilitated Photius, but evidence is lacking that Alandos was the same as Balandus.
The last record of Blaundus dates from the 12th century.
The bishopric of Blaundus was nominally revived in 1953 as a titular see of the lowest (episcopal) rank, but has been vacant since January 31, 1971, after only two incumbents:
