Murad I succeeds Orhan as Ottoman sultan

1359

The third Ottoman ruler, son of a Greek concubine, inherited a beylik now bestriding the Dardanelles and growing rapidly on both sides of the strait. He would push north into Thrace, west into Macedonia, force Bulgarian and Serbian princes to become his vassals, organize the first regular Janissary corps, and die on the field of Kosovo in 1389.
