Editing Lydia (section)

=== Eastern Roman Empire (and Crusader) age ===
Under the Eastern Roman emperor Heraclius (610–641), Lydia became part of [[Anatolikon]], one of the original ''[[Theme (Eastern Roman administrative unit)|themata]]'', and later of [[Thrakesion]]. Although the [[Seljuk Turks]] conquered most of the rest of Anatolia, forming the [[Sultanate of Ikonion]] (Konya), Lydia remained part of the Byzantine Empire. While the Venetians occupied Constantinople and Greece as a result of the [[Fourth Crusade]], Lydia continued as a part of the Eastern Roman [[rump state]] called the [[Empire of Nicaea|Nicene Empire]] based at [[İznik|Nicaea]] until 1261.
