Before the death, in 1258, of Theodore Lascaris the Second, the ruler of Nicaea was acknowledged emperor, not merely throughout the northern part of Asia Minor, but in the kingdom of Macedonia, and even in a considerable portion of Thrace. His successor, John, was a boy. John’s guardian was Michael Palaeologus, who was proclaimed emperor in January 1259–60. Seeing that there was some disorder in Nicaea, occasioned by the disputes between those in favour of the boy, who, in the ordinary course of succession, would have been emperor, and those who had recognised that the times were too critical to allow him to reign, and had consequently followed Michael, the Latin emperor, Baldwin, judged the moment opportune to stipulate for concessions. Accordingly he sent a mission to Nicaea to learn what Michael would give in order to avoid war. The historian Acropolitas, who was at Nicaea at the time, records what passed. The emperor mocked the ambassadors. They asked that he should surrender Salonica. The reply was that that city was the emperor’s birthplace; how could he part with it? They suggested Seres. The emperor responded that what they were asking was neither just nor decent, since he had received it from his father. ‘Give us, then, Bolero.’ But that was the emperor’s hunting-ground, and could not be spared. ‘What, then, will you give us?’ ‘Nothing whatever,’ replied the emperor. ‘But if you want peace with me, it is well, because you know me, and that I can fight. Pay me part of the tribute collected at Constantinople, and we shall be at peace.’ No better terms were to be had, and the ambassadors left. Michael probably understood that his refusal would be followed by war. He therefore visited the fortifications already gained in Thrace by the Greeks, strengthened them, and within a few months the Latin empire was reduced to the occupation of Constantinople and a small strip around it. In the following year, 1260, Michael’s general, Strategopulus, was entrusted with the command in Thrace. He stormed Selymbria (the modern Silivria), and tried but failed to capture Galata, which was already in the occupation of the Genoese. Thereupon a truce was made for one year. Seeing that the Venetians, whose great power in the Levant dates from the fall of Constantinople in 1204, in which they had played so important a part, still maintained their connection with the empire on the Bosporus and, indeed, continued to be the principal source of such strength as it possessed, Michael, to the great indignation of the pope and the West, made an alliance with their rivals, the Genoese, an alliance which was the foundation of their supremacy in trade in the Black Sea.
