By the 7th century, the Serbs scattered all the way south to the Peloponnesus and other regions of Greece, while the emperor Heraclius originally settled them around Thessaloniki. Emperor Justinian II resettled some Serbs from the surroundings of Thessaloniki to Bithynia, in Asia Minor, in 688–689. There, the Serbs already founded the town of Gordoserba (City of Serbs). Among the participants of the Trullan Council, held in Constantinople in 692, bishop Isidore of Gordoserba was mentioned, which is the first mention of the Serbian name in the south of Europe.
