Having joined the Serbian military in 1874, he fought against the forces of the Ottoman Empire in 1876. Over the following years, he climbed up the ranks of the Serbian Army and fought against Bulgarian forces in 1885. He eventually became the Serbian Minister of War in April 1908 and was responsible for instituting changes in the Serbian Army.
Stepanović commanded Serbian forces during the two Balkan Wars and led the Serbian Second Army during World War I. After Battle of Cer he was promoted to second Field Marshal. He died in Čačak on 29 April 1929.
Stepan "Stepa" Stepanović was born on 28 February 1856 in the village of Kumodraž, near Belgrade. He was the fourth child and third son of Ivan and Radojka Stepanović (née Nikolić). Stepanović was named after his grandfather Stepan, from whom his family's surname originated. There are two theories of his family origins. The first states that Stepanovic’s ancestors, who were known as Živanović, came from the regions of Bosnia and Lika. The second theory is that his ancestors came from the vicinity of Leskovac and Pirot during the Great Serb Migrations.
