Note 310 — Chapter III · MURAD THE OSMANLIS LAY THE FOUNDATIONS OF AN EMPIRE IN EUROPE
Reading edition
Although Engel says 1353, others 1356, and the Rumanian chronicle 1371, there can be no question that 1365 is the correct date; for both Byzantine and Ottoman historians speak of Alexander as Bulgarian Czar in 1364, and do not mention him later, while Sisman and his brothers come immediately into prominence.
