The Empire of Thessalonica is a historiographic term used by some modern scholars to refer to the short-lived Greek state centred on the city of Thessalonica between 1224 and 1246 and ruled by the Komnenodoukas dynasty of the Despotate of Epirus. At the time of its establishment during the struggle for Constantinople, the Empire of Thessalonica, under the capable Theodore Komnenos Doukas, rivaled the Empire of Nicaea and the Second Bulgarian Empire as the strongest state in the region, and aspired to capturing Constantinople, putting an end to the Latin Empire, and restoring the Byzantine Empire that had been extinguished in 1204.

Empire of Thessalonica in Depth
Rise and decline
The capture of Thessalonica, traditionally the second city of the Byzantine Empire after Constantinople, allowed Theodore to challenge the Nicaean claims on the Byzantine imperial title. With the support of the bishops of his domains, he was crowned emperor at Thessalonica by the Archbishop of Ohrid, Demetrios Chomatenos. The date is unknown, but has been placed either in 1225 or in 1227/8. Having openly declared his imperial ambitions, Theodore turned his gaze onto Constantinople. Only the Nicaean emperor John III Doukas Vatatzes, and the Bulgarian emperor Ivan II Asen were strong enough to challenge him.
Background
After the Fourth Crusade captured Constantinople in April 1204, the Byzantine Empire dissolved and was divided between the Crusader leaders and the Republic of Venice. The Latin Empire was set up in Constantinople itself, while most of northern and eastern mainland Greece went to the Kingdom of Thessalonica under Boniface of Montferrat. At the same time, two major native Byzantine Greek states emerged to challenge the Latins and claim the Byzantine inheritance, the so-called Empire of Nicaea under Theodore I Laskaris in Asia Minor, and the so-called Despotate of Epirus in western Greece under Michael I Komnenos Doukas, while a third state, the so-called Empire of Trebizond, established a separate existence on the remote shores of the Pontus.
