Murad I (1319 (or 1326) – 1389; nick-named Hüdavendiğar, the God-like one) was the ruler of the Ottoman Empire from 1359 to 1389. He was the son of Orhan I and the Byzantine princess Helen (Nilofer) and became the ruler following his father's death in 1389. He established the Empire by building up a society and government in the newly conquered city of Adrianople (Edirne in Turkish) and by expanding the realm in Europe, bringing most of the Balkan under Ottoman rule and forcing the Byzantine emperor to pay him tribute. It was Murad who established the former Osmanli tribe into an empire. He established the title of sultan in 1383 and the corps of the Janissaries and the devşirm recruiting system. He also organised the government of the Divan, the system of timars and timar-holders (timariots) and the military judge, the kaziasker. He also established the two provinces of Anadolu (Anatolia) and Rumili (Europe).
Murat, a true son of the Revolution, wrote Metternich, in the same letter, did not hesitate to form projects of conquest when all his care should have been limited to simple calculations as to how to preserve his throne.
Murats suspicions of Austrian sincerity were now confirmed; he realized that there was no question now of his obtaining any extension of territory at the expense of the states of the Church, and that in the Italy as reconstructed at Vienna his own position would be intolerable.
Murats aggressive attitude, and the unrest in Italy, are largely due to the threatening attitude of France.
