Was not Constantinople in a pretty bad position, so they had to ask Blanche de Castille and whoever was ruling France for help around 1240 ? Constantinople ruler at the time, Baldwin II was either killed or captured Sources agree that the city started paying tribute to the mongol. ( one is a document excommunicating Baldwin for accepting overloadship from the mongols ) So the city was not taken but the situation was pretty bad. Similarly, Bulgaria and Hungary were taken too if I’m remember correctly.
