Names of the Croats and Croatia

The non-native name of Croatia (Croatian: Hrvatska) derives from Medieval Latin Croātia, itself a derivation of the native ethnonym of Croats, earlier *Xъrvate and modern-day Croatian: Hrvati. The earliest preserved mentions of the ethnonym in stone inscriptions and written documents in the territory of Croatia are dated to the 8th-9th century, but it is of an earlier date due to lack of preserved historical evidence as the arrival of the Croats is historically and archaeologically dated to the 6th-7th century. The ethnonym of the Croats with many derivative toponyms and anthroponyms became widespread all over Europe.

There exist many and various linguistical and historical theories on the origin of the ethnonym. It is usually considered not to be of Slavic but rather Iranian language origin. According to the most probable Iranian theory, the Proto-Slavic *Xъrvat- < *Xurwāt- derives from Proto-Ossetian / Alanian *xurvæt- or *xurvāt-, in the meaning of "one who guards" ("guardian, protector"), which was borrowed before the 7th century. The relation to the 3rd-century Scytho-Sarmatian form Khoroáthos (alternate forms comprise Khoróatos and Khoroúathos) attested in the Tanais Tablets, near the border of present day Ukraine and European Russia, although possible remains uncertain.
