Note 5 — Chapter I · : Historical Retrospect
Reading edition
Knez Lazar ruled from 1371 to 1389, and during his reign he made an alliance with Ban5 Tvrtko of Bosnia against the Turks. Ban Tvrtko proclaimed himself King of Bosnia, and endeavoured to extend his power in Hungary, whilst Knez Lazar, with the help of a number of Serbian princes, prepared for a great war against the Turks. But Sultan Amourath, informed of Lazar’s intentions, suddenly attacked the Serbians on June 15 1389, on the field of Kossovo. The battle was furious on both sides, and at noon the position of the Serbians promised ultimate success to their arms.
