The same year, Odilo Globocnik joined the army, via a military school. The war ended his military education prematurely. Odilo moved with his family to Klagenfurt in Carinthia. There as a teenager, he joined the pro-Austrian volunteer militia fighting Slovene volunteers and, later, the Yugoslav Army during the Carinthian War (1918–19). In 1920, he worked as an underground propagandist for the Austrian cause during the Carinthian Plebiscite.
