But it was of little use to sweep away Cantacuzenus while Orkhan’s Turks were in Thrace. The Ottomans had come as auxiliaries in the war, but they were resolved to stop as principals. Suleiman, the son of Orkhan, seized Gallipoli for himself, filled it with Turkish families, and made it a permanent settlement. This was the first Ottoman foothold in Europe, but it was not long to remain isolated. In 1359 Orkhan died, and his successor, Murad I., determined to cross over into Europe, and try the fortune of his arms. John Paleologus was not a worse man than his immediate predecessors on the throne, but thanks to Cantacuzenus he had far less resources than even they had possessed. Two years of fighting sufficed to put Thrace in the hands of Murad from sea to sea. A decisive battle in front of Adrianople in 1361 was the finishing stroke, and the empire became a mere head without a body; its last home-province had been lopped away, and beyond the walls of Constantinople no land acknowledged John V. as sovereign save the district of Thessalonica and the Peloponnesus. Why Murad I. did not finish the task he had begun, and take Constantinople itself, it is hard to discern. Its walls were still formidable, and the Genoese and Venetians could still protect it on the side of the sea. But a siege pressed firmly to an end must at last have triumphed over the mere inert resistance of stone and mortar, unsupported by an adequate garrison within. However, Murad preferred to press on against worthier adversaries than the weak Paleologus, and spent his life in incessant and successful wars with the Servians, the Bulgarians, and the Seljouk Emirs of Southern Asia Minor. In a reign of thirty years he extended his borders to the Balkans on the north, and annexed large tracts of Seljouk territory from his brother Emirs in Asia Minor.
