The name of Croatia derives from Medieval LatinCroātia, itself a derivation of the native ethnonym of Croats, earlier Xъrvatъ and modern-day Hrvati.
Earliest record
Although in 2005 it was archaeologically confirmed that the ethnonym Croatorum is mentioned in a church inscription found in Bijaći near Trogir dated to the end of the 8th or early 9th century, it is generally accepted that the first attestation of the ethnonym is in the Latin charter of Duke Trpimir from 852, the original of which has been lost. A copy has been preserved in a 1568 transcript; Lujo Margetić proposed in 2002 that the document is in fact of legislative character, dating to 840. In it is mentioned: The oldest stone inscription is the Latin Branimir Inscription, where Duke Branimir is mentioned: The monument with the earliest writing in the Croatian language containing the ethnonym xъrvatъ is the Baška tablet from 1100, which reads: zvъnъmirъ kralъ xrъvatъskъ.
Etymology
The exact origin and meaning of the ethnonym, in singular, Hrvat is poorly known and still subject to scientific disagreement. It is believed that the word might not be of native Slavic lexical stock, but a borrowing. Common theories from the 20th century derive it from an Iranian origin, the root word being a third-century Scytho-Sarmatian form attested in the Tanais Tablets as Χοροάθος. This form was used to substantiate the derivation of Proto-Slavic *xъrvatъ from the Old Persian xaraxwat-, attested by the Old Iranian toponym Harahvait-, the native name of Arachosia. "Arachosia" is the Latinized form of Ancient Greek Ἀραχωσία ; in Old Persian inscriptions, the region is referred to as Harahuvatiš. In Indo-Iranian it actually means "one that pours into ponds", which derives from the name of the Sarasvati River of Rigveda. However, although the somewhat suggestive similarity, the connection to the name of Arachosia is etymologically incorrect. The first etymological thesis about the name of the Croats stems from Constantine Porphyrogennetos, who connected the different names of the Croats, Βελοχρωβάτοι and Χρωβάτοι, with the Greek word χώρα : "Croats in Slavic language means those who have many lands". In the 13th century, Thomas the Archdeacon considered that it was connected with the name of inhabitants of the Krk isle, which he gave as Curetes, Curibantes. In the 17th century, Juraj Ratkaj found a reflexion of the verb hrvati "to wrestle" in the name. In the 19th century, many different derivations were proposed for the Croatian ethnonym:
S. Mikucki connected it with Old-Indian šarv- "strike";
Pavel Jozef Šafárik derived it from xrъbъtъ, xribъtъ, xribъ "ridge, highlanders", whereas Franz Miklosich said it derived from hrъv "dance";
Đ. Daničić considered its root to be *sar- "guard, protect";
L. Geitler considered that the Lithuanian words šárvas "armor" and šarvúotas "cuirassier" might be related to the ethnonym;
Fyodor A. Braun saw the German Harfada, which would be the German name of the Carpathian Mountains, as the origin of an intermediate form Harvata;
Rudolf Much connected it to a Proto-Germanic word hruvat- "horned", or – and Z. Gołąb proposed – "warriors clad with horn-armor", as a self-designation;
A. Bruckner linked it to Slovak charbati se "to oppose" or via skъrv-/xъrv- to the Lithuanian šárvas "armor";
K. Oštir considered valid a connection with an unspecified Thraco-Illyrian word xъrvata- "hill";
Max Vasmer first considered it as a loanword from Old-Iranian, haurvatā "shepherd", later also from Old-Iranian hu-urvatha- "friend".
Zupanič additionally proposed Lezgian origin from Xhurava and plural suffix -th, meaning "municipalities, communities".
M. Budimir saw in the name a reflexion of Indo-European *skwos "gray, grayish", which in Lithuanian gives širvas;
S. K. Sakač linked it with the Avestan name Harahvaitī, which once signified the southwestern part of modern Afghanistan, the province Arachosia.
G. Vernadsky considered a connection to the Chorasmí from Khwarezm, while F. Dvornik a link to the Krevatades or Krevatas located in the Caucasus mentioned in the De Ceremoniis.
V. Miller saw in the Croatian name the Iranian hvar- "sun" and va- "bed", while P. Tedesco had a similar interpretation from Iranian huravant "sunny";
O. Kronsteiner suggested it might be derived from Tatar-Bashkir *chr "free" and *vata "to fight, to wage war".
From the theses the most widely accepted is the derivation by Oleg Trubachyov from *xar-vat, which derives from the etymology of Sarmatians name, the Indo-Aryan*sar-mat "feminine", in both Indo-Iranian adjective suffix -mat/wat, and Indo-Aryan and the Indo-Iranian *sar- "woman", which in Iranian gives *har-. According to Radoslav Katičić this thesis doesn't entirely fit with the Croatian ethnonym, as the original form was Hrъvate not Hъrvate, and the vowel "a" in the Iranian harvat- is short, while in the Slavic Hrъvate it is long. Katičić concluded that of all the etymological considerations the Iranian is the least unlikely. Ranko Matasović also considered it of Iranian origin. The Medieval Latin name "Croātia" is derived from North-West Slavicxrovat-, by liquid metathesis from Common Slavic*xorvat-, from Proto-Slavic, i. e. Iranian, *xarwāt-. The Croatian ethnonym Hrvat in the Kajkavian dialect also appears in the form Horvat, while in the Chakavian dialect in the form Harvat.
Distribution
Croatian place names can be found in northern Slavic regions such as Moravia and Slovakia, along the riverSaale in Germany, in Austria and Slovenia, and in the south in Greece and Albania. Thus in the Duchy of Carinthia one can find Hrvatski kotar and Chrowat along upper Mura; in Middle Ages the following place names have been recorded: Krobathen, Krottendorf, Krautkogel; Kraut near Spittal. In the Duchy of Styria there are toponyms such as Chraberstorf and Krawerspach near Murau, Chrawat near Laas in Judendorf, Chrowat, Kchrawathof and Krawabten near Leoben. Along middle Mura Krawerseck, Krowot near Weiz, Krobothen near Stainz and Krobathen near Straganz. In Slovenia there are Hrovate and Hrovača; in Germany along Saale river there were Chruuati near Halle) in 901 AD, Chruuati in 981 AD, Chruazis in 1012 AD, Churbate in 1055 AD, Grawat in 1086 AD, Curewate, Großkorbetha and Kleinkorbetha, and Korbetha west of Leipzig; In Moravia are Charwath or Charvaty near Olomouc, in Slovakia are Chorvaty and Chrovátice near Varadka. The Charvatynia near Kashubians in district Neustadt is debatable. In the southern Balkans, North Macedonia has a place named Arvati situated near lower Prespa; in Greece there is a Charváti in Attica and Harvation in Argolis, as well as Charváta on Crete; and Hirvati in Albania.
