On 18 October Bulgaria declared war on the Ottoman Empire, joining a host of other European countries in the First Balkan War. Overshadowed by the First World War, this conflict saw the Ottomans fighting against the Balkan League (Bulgaria, Greece, Serbia and Montenegro) in a clash that would see the Ottoman Empire lose large portions of its European territories.
