:{{Small|'''''Note:''' Roman rule in Constantinople was interrupted with the [[sack of Constantinople|capture and sack of the city]] by the [[Fourth Crusade|crusaders]] in 1204, which led to the establishment of the [[Frankokratia]]. Though the crusaders created a new line of [[Latin emperor]]s in the city, modern historians recognize the line of emperors of the Laskaris dynasty, reigning in [[Empire of Nicaea|Nicaea]], as the legitimate Roman emperors during the [[struggle for Constantinople]] because the Nicene Empire eventually retook the city.{{Sfn|Treadgold|1997|p=734}} For other lines of claimant emperors, see [[List of Trapezuntine emperors]] and [[List of Thessalonian emperors]].''}}
