Svetozar Boroević von Bojna (or Borojević) (13 December 1856 – 23 May 1920) was an Austro-Hungarian field marshal who was described as one of the finest defensive strategists of the First World War. He commanded Austro-Hungarian forces in the Isonzo front, for which he was nicknamed the "Lion of Isonzo".
For his service during the First World War, Boroević rose to the rank of Feldmarschall before the end of the war in 1918, becoming the first and only Austro-Hungarian field marshal of South Slavic descent.
