Foreign policy of the Lascarids and the restoration of the Byzantine empire.

        After the defeat of the Latins at Hadrianople, Theodore’s situation became temporarily a little easier. Baldwin’s successor on the Constantinopolitan throne, however, his brother Henry, an energetic and talented leader and ruler, after his coronation in St. Sophia somewhat recovered from the reverse with the Bulgars and again opened hostilities against Theodore, having it in mind to annex the possessions of Nicaea to the Latin Empire. The Emperor of Nicaea could not, by force of arms, check the successes of the Latins. But the Bulgarian danger to the Latins and the Seljuq danger to Theodore compelled both of them to come to an agreement and to conclude a truce, by the terms of which Theodore had to pull down several fortresses.[31]
