Constantinople was recaptured by the "Byzantines" in 1261 and Emperor Baldwin II fled. Various popes tried to arrange a new crusade to put the Latin Emperor back on the throne, and "Byzantine" Emperor Andronikos II Palaiologos tried to arrange a marriage of his heir Michael IX with Empress Catherine I, heiress of the Latin Empire, in order to avoid the danger of a crusade. He failed, but did marry as his second wife YolandeYolanda of Montferrat in 1284, who brought her family's claim to the Kingdom of Thessalonika with her, and a son of theirs became Margrave of Montferrat when Yolanda's brother died in 1305.
Then in 1274 Emperor Philip of Courtenay, son of Baldwin II, granted the rights to the Kingdom of Thessalonika to Philip of Sicily (1255/56-1277), even though Margrave William VII of Montferrat and Duke Robert II of Burgundy already had claims to the Kingdom of Thessalonika.
Philip of Sicily's claim died with him in 1277, William VII's was given to his daughter Yolanda when she married Emperor Andronikos II in 1284, And Duke Odo IV of Burgundy sold his rights to the Kingdom of Thessalonika and the Principality of Achaea to Count Louis of Cleremont, Firstfirst Duke of Bourbon, in 1320.
