Revenge is defined as the act of committing a harmful action against a person or group in response to a grievance, be it real or perceived.

The Kosovo Myth, also known as the Kosovo Cult and the Kosovo Legend, is a Serbian nation-building myth based on legends about events related to the Battle of Kosovo (1389). It has been a subject in Serbian folklore and literary tradition and has been cultivated 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, and in certain periods of other South Slavic nations.
