Ottoman Hungary encompassed those parts of the Kingdom of Hungary which were under the rule of the Ottoman Empire from the occupation of Buda in 1541 for more than 150 years, until the liberation of the area under Habsburg leadership (1686–1699). The territory was incorporated into the empire, under the name Macaristan. For most of its duration, Ottoman Hungary covered Southern Transdanubia and almost the entire region of the Great Hungarian Plain.

Hungarian is a Uralic language spoken in Hungary and parts of several neighbouring countries. It is the official language of Hungary and one of the 24 official languages of the European Union. Outside Hungary, it is also spoken by Hungarian communities in southern Slovakia, western Ukraine (Transcarpathia), central and western Romania (Transylvania), northern Serbia (Vojvodina), northern Croatia, northeastern Slovenia (Prekmurje), and eastern Austria (Burgenland).
