The First Serbian Volunteer Division (also known as the First Serbian Division and Serbian First Division) was a military force created in 1916 by political figure Nikola Pašić and his associates in the city of Odessa. It was primarily made up of various Serb peoples, a great many of them former prisoners of war. It holds a particularly significant place in World War I history due both to its intermingling of different ethnicities, including Bosnians, Czechs, and Slovaks, as well as its role in opposing the Central Powers after the then regular Serbian army had suffered an immense setback.
