Gusle in the context of "Serbian epic poetry"

The Kosovo Myth (Serbian: Косовски мит / Kosovski mit), also known as the Kosovo Cult (Косовски култ / Kosovski kult) and the Kosovo Legend (Косовска легенда / Kosovska legenda), is a Serbian national myth based on legends about events related to the Battle of Kosovo (1389). It is rooted in Prince Lazar's apocryphal choice during the battle at the Kosovo Polje, where he is said to have rejected an earthly victory over the Ottoman Sultan Murad I and chose to die as a Christian martyr in favor of a "heavenly kingdom". This choice, as the narrative suggests, was intended to position Serbs as a chosen people and secure a spiritual covenant with God and a place in the Kingdom of Heaven.

It has been a major subject in Serbian folklore and literary tradition and has been cultivated through oral epic poetry and guslar poems. The final form of the legend was not created immediately after the battle but evolved from different originators into various versions. In its modern form it emerged in 19th-century Serbia and served as an important constitutive element of the national identity of modern Serbia and its politics.
