Historiographical synthesis & structured realm registry
The Empire of Nicaea, also known as the Nicene Empire, was the largest of the three Greek rump states founded by the aristocracy of the Byzantine Empire that fled when Constantinople was occupied by Western European and Venetian armed forces during the Fourth Crusade, a military event known as the Sack of Constantinople; Latin Empire, was established by an army of Crusaders and Venice after the capture of Constantinople and the surrounding environs. Like the other Byzantine rump states that formed due to the 1204 fracturing of the empire, such as the Empire of Trebizond and the Despotate of Epirus, it was a continuation of the eastern half of the Roman Empire that survived well into the Middle Ages.

Nicaean Empire in Depth
History
In 1204, Byzantine emperor Alexios V Doukas Mourtzouphlos fled Constantinople after crusaders invaded the city. Soon after, Theodore I Laskaris, the son-in-law of Emperor Alexios III Angelos, was proclaimed emperor, but he too, realizing the situation in Constantinople was hopeless, fled to the city of Nicaea in Bithynia.
The Latin Empire, established by the Crusaders in Constantinople, had poor control over former Byzantine territory, and Greek successor states of the Byzantine Empire sprang up in Epirus, Trebizond, and Nicaea. Trebizond had broken away as an independent state a few weeks before the fall of Constantinople. Nicaea, however, was the closest to the Latin Empire and was in the best position to attempt to re-establish the Byzantine Empire.
Military
The Nicene Empire consisted of Byzantium's most highly populated Greek region, with the exception of Thrace which was under Latin/Bulgar control. As such, the Empire was able to raise a reasonably numerous military force of around 20,000 soldiers at its height – numbers recorded as participating in its numerous wars against the Crusader states.
The Nicenes continued some aspects of the Komnenian army, but without the resources available to the Komnenian emperors the Nicene Byzantines could not match the numbers, nor the quality, of the armies that the emperor Manuel I Komnenos and his predecessors had fielded.
