Jelena was the wife of King Vukašin Mrnjavčević, who ruled as co-king alongside the nominal Serbian emperor Uroš V following the fragmentation of Dušan's empire. Vukašin died at the Battle of Maritsa in 1371 — a catastrophic Ottoman victory that effectively ended Serbian control over Macedonia. That Jelena continued issuing coinage in her own name after his death, through the reign of her son Marko Kraljević, is unusual for the period and reflects the political complexity of the Mrnjavčević domain as it steadily contracted under Ottoman pressure.
