This paper presents the life and the military career of field marshal Svetozar Borojević with the special emphasis on his role on the Isonzo Front. His early life and the beginnings of his military career are briefly described. His climb trough the ranks of the Austro-Hungarian military is one of the fastest ever recorded. After his first war experience during the battles in Bosnia and Herzegovina, his career continued with an upwards trajectory. After the start of World War I, he was sent to the Eastren Front considering he was in command of the corps near that front. Thats where he proved himself as a great military leader and in difficult conditions he was still achieving success. After Italy entered the war on the side of the Entente, a new front opened on the southwestren border of the Monarchy and Borojević was sent as a commander of the Fifth Army to establish defensive lines and defend the Isonzo Front. He succeeded in doing that despite 11 heavy italian offensives, and after the arrival of German units they managed to push the Italians far away from the Isonzo river. Despite the great success, the Austro-Hungarian Empire dissolved because of a variety of its internal factors, so its army fell apart too. Borojević shares the fate of the Monarchy and soon dies in 1920, forgotten by everyone. Because of his role and place in the Austro-Hungarian and Croatian history, he is undoubtedly one of its greatest military leaders ever.
