ecumenical council, aiming at the reunion of the Churches. In response, a delegation of Franciscans and Dominicans arrived at Nicaea in 1234, but their remit was limited: they had no authority to conduct any negotiations, only to sound out the emperor and the patriarch. The Latin delegation attended a council held in Nymphaion, but it broke up in acrimony between the Greeks and Latins. The papal envoys fled back to Rome, while the Nicaeans went on to attack Constantinople.
