 "Slovenia" became a "de facto" distinctive administrative and political entity for the first time in 1918, with the unilateral declaration of the State of Slovenes, Croats and Serbs, that Slovenia.Although Slovenia did not exist as an autonomous administrative unit between 1921 and 1941, the Drava Banovina of the Kingdom of Yugoslavia was frequently called simply "Slovenia", even in some official documents.Consequently, most Slovene scholars prefer to refer to the "Slovene Lands" in English rather than "Slovenia" to describe the territory of modern Slovenia and neighbouring areas in earlier times.
