The name of Croatia derives from Medieval Latin Croātia, from Dux Croatorum ("Duke of Croatians") attested in the Branimir Inscription, itself a derivation of North-West Slavic *Xrovat-, by liquid metathesis from proposed Common Slavic period *Xorvat-, from proposed Proto-Slavic *Xarwāt- (*Xъrvatъ) or *Xŭrvatŭ (*xъrvatъ). The origin of the name is uncertain, but is thought to be a Gothic or Indo-Aryan term assigned to a Slavic tribe. The oldest preserved record of the Croatian ethnonym *xъrvatъ is of variable stem, attested in the Baška tablet in style zvъnъmirъ kralъ xrъvatъskъ ("Zvonimir, Croatian king").
The first attestation of the Latin term is attributed to a charter of duke Trpimir from the year 852. The original is lost, and just a 1568 copy is preserved—leading to doubts on the authenticity of the claim. The oldest preserved stone inscription is the 9th century Branimir Inscription (found near Benkovac), where Duke Branimir is styled as Dux Cruatorvm. The inscription is not dated accurately, however, Branimir ruled Croatia in 879–892.
Prehistory and antiquity
The area known as Croatia today was inhabited throughout the prehistoric period. Fossils of Neanderthals dating to the middle Palaeolithic period have been unearthed in northern Croatia, with the most famous and the best presented site in Krapina. Remnants of several Neolithic and Chalcolithic cultures were found in all regions of the country. The largest proportion of the sites is in the northern Croatia river valleys, and the most significant cultures whose presence was discovered include Starčevo, Vučedol and Baden cultures. The Iron Age left traces of the early Illyrian Hallstatt culture and the Celtic La Tène culture.
Much later, the region was settled by Liburnians and Illyrians, while the first Greek colonies were established on the islands of Korčula, Hvar and Vis. In 9 AD the territory of today's Croatia became part of the Roman
