Косовски бој or Бој на Косову
On June 28, 1389 the Ottoman Empire defeated Serbia in the Battle of Kosovo
-St. Vitus' Day-
The First Battle of Kosovo occurred on the field of Kosovo Polje on June 28, 1389, when the puling knez (prince) of Serbia, Lazar Hrebeljanoviæ, marshalled a coalition of Christian soldiers, made up of Serbs, but also of Bosnians, Magyars, Albanians, and a troop of Saxon mercenaries. Sultan Murad I also gathered a coalition of soldiers and volunteers from neighboring countries in Anatolia and Rumelia. Exact numbers are difficult to come by, but most reliable historical accounts suggest that the Christian army was heavily outnumbered by the Ottomans. The combined numbers of the two armies are believed to be less than 100,000. The Serbian-led armies were defeated and Lazar was slain, although Murad I was killed by the Milo Obiliæ, whose origin is disputed. Although the battle has been mythologised as a great Serbian defeat, at the time opinion was divided as to whether it was a Serbian defeat, a stalemate or possibly even a Serbian victory. Serbia maintained its independence and sporadic control of Kosovo until a final defeat in 1455, following which Serbia and Kosovo became part of the Ottoman Empire and a Turkish ally.
Second Battle of Kosovo
The Second Battle of Kosovo was fought over the course of a two-day period in October 1448, between a Hungarian force lead by John Hunyadi and an Ottoman army lead by Murad II. Significantly larger than the first battle, with both armies numbering twice that of the first battle, the ending was the same, and the Hungarian army was defeated in the battle and pushed from the field. Contray to popular myth, the Albanian hero Skanderbeg did not take part in the battle. When his Albanian troops moved to join the Hungarian army, they were delayed by the ambush of Ðurað Brankoviæ and never reached the battlefield. Although the loss of the battle was a setback for those resisting the Ottoman invasion of Europe at that time, it was not a 'crushing blow to the cause'. Hunyadi was able to maintain Hungarian resistance to the Ottomans during his lifetime.
