John II Komnenos
Similarly, in 1129–1130 some Serbs were likely settled in Bithynia by John II Komnenos, due to the mention of a settlement called Servochōria () near Nicomedia, mentioned in the 13th century source "Partitio regni Graeci" (1204). Some identified Gordoserba with this Servochōria, but the connection is uncertain.
