The Serblias family (Greek: Σερβλίας) was a Byzantine family that was active between the 11th and 13th centuries, employed in civil service in the central and provincial government.^[1] A part of the family was related to the Spanopouloi in the 1090s.^[1] The etymology of the name derives from their origin, either Serbia (Σερβλία), or the fortress town of Servia (τὰ Σἐρβλια).^[2] Contemporarily, the family used its name as an argument to claim descent from the ancient Servilia gens. Writing a letter to one Nikephoros Serblias, John Tzetzes addressed him as "descendant of the Servilian Caesars" (ὁ Σερβιλίων Καισάρων ἀπόγονος).^[3]
