The First Battle of Kosovo Polje was fought on 15 June 1389 between Prince Lazar's Balkan coalition and the army of Sultan Murad I. Romanian tradition associates Mircea the Elder with a Wallachian contingent in the anti-Ottoman coalition, though the exact scale of Wallachian participation remains debated.
