In 1358 Solyman, who had shown great capacity when in command of the Ottoman army, met with his death by a fall from his horse when engaged in his favourite sport of falconry. His father, Orchan, died in the following year at the age of seventy-two. He had enormously increased the Ottoman dominions. He had achieved the first great object of his ambition, that of driving the Byzantines from their remaining possessions in Asia. He had rounded off his boundaries in the north-west corner of Anatolia by annexing Mysia. He had invaded Europe and had extended Ottoman rule over a part of Thrace. He had reduced the Byzantine Emperor almost to vassalage. These great results had been achieved not so much by force of arms as a general, for he is not credited with any great victory in the field, or by successful assaults on any great fortresses, as by crafty diplomacy and intrigue, backed up by superior force, and by taking advantage of the feebleness and treachery of the Byzantines. He also forged the military weapon by which his son, Murad, was able to effect far greater territorial conquests, both in Europe and Asia.

He soon proved himself to be eminently qualified to rule by his untiring activity and vigour, his genius for war, and his wise and sane statesmanship. He was illiterate. He could not even sign his name. There is extant in the archives of the city of Ragusa a treaty with its petty republic, which Murad, in 1363, signed by dipping his hand in ink and impressing it with his finger marks. The ‘tughra’ thus formed became the official signature of subsequent Sultans of Turkey. Osman and Orchan between them created the Ottoman dynasty and State, but Murad must be credited with having founded the Empire in the sense of imposing Ottoman rule on subject races.
