Timur’s hosts, after ravaging the whole of Asia Minor, departed like a swarm of locusts which has denuded a district of its produce and then seeks fresh ground. They returned to Central Asia. They left nothing behind in Asia Minor of Tartar rule, either of an army or of an administration. The field was left open to the Ottomans to fight among themselves and their former vassals and neighbours for such a settlement as could be achieved by the strongest of them. Of the six sons of Bayezid, five fought with him at Angora in command of divisions of his army. One of them, Mustapha, was supposed to be among the slain; another, Musa, was taken prisoner and shared the captivity of his father. The other three escaped. The eldest of them, Solyman, accompanied by the Grand Vizier, Ali, and Hassan, the Agha of the Janissaries, made his way to Adrianople, where, on the death of Bayezid, he had himself proclaimed Sultan, and exercised power as such over the European provinces of the Empire. Issa, a younger son, fled to Brusa, where he also claimed to be successor to his father, and Mahomet, the youngest son, but by far the ablest, retired to Amasia, a small principality in the north-east of Asia Minor. He there assumed authority over the district. After the death of their father these three claimants for succession to his Empire fought it out between themselves, and, later on, a fourth claimant was added to the list in Musa, who had been set free by Timur, in order that he might convey the dead body of his father for interment at Brusa. The earliest conflict was between Mahomet and Issa. Mahomet offered to divide between them the Ottoman possessions in Asia. Issa refused and claimed the whole of them. He was defeated and fled to Europe, where he sought the assistance of Solyman, who had firmly established himself in the Ottoman dominions there, and who was now able to lead an army into Asia Minor in support of Issa. Mahomet was hard pressed by Solyman. He sent Musa across the Straits to effect a diversion by raising revolt against Solyman in Europe. This had the desired effect, and Solyman was compelled to return to Adrianople. After his departure Mahomet succeeded in defeating Issa again, and the latter disappeared and was heard of no more.
