Kingdom of Croatia (925–1102)

Coronation of King Tomislav (modern painting by Oton Iveković)

Croatia was elevated to the status of kingdom somewhere around 925. Tomislav was the first Croatian ruler whom the papal chancellery honoured with the title "king".[17] It is generally said that Tomislav was crowned in 925, but it is not known when or by whom he was crowned, or, indeed, if he was crowned at all.[1] Tomislav is mentioned as a king in two preserved documents published in the Historia Salonitana. First in a note preceding the text of the conclusions of the Council of Split in 925, where it is written that Tomislav is the "king" ruling "in the province of the Croats and in the Dalmatian regions" (in prouintia Croatorum et Dalmatiarum finibus Tamisclao rege),[18][19][20] while in the 12th canon of the Council conclusions the ruler of the Croats is called "king" (rex et proceres Chroatorum).[20] In a letter sent by Pope John X, Tomislav is named "King of the Croats" (Tamisclao, regi Crouatorum).[18][21] The Chronicle of the Priest of Duklja titled Tomislav as a king and specified his rule at 13 years.[18] Although there are no inscriptions of Tomislav to confirm the title, later inscriptions and charters confirm that his 10th century successors called themselves "kings".[19] Under his rule, Croatia became one of the most powerful kingdoms in the Balkans.[22][23]

Tomislav, a descendant of Trpimir I, is considered one of the most prominent members of the Trpimirović dynasty. Sometime between 923 and 928, Tomislav succeeded in uniting the Croats of Pannonia and Dalmatia, each of which had been ruled separately by dukes. Although the exact geographical extent of Tomislav's kingdom is not fully known, Croatia probably covered most of Dalmatia, Pannonia, and northern and western Bosnia.[24] Croatia at the time was administered as a group of eleven counties (županije) and one banate (Banovina). Each of these regions had a fortified royal town.

Croatia soon came into conflict with the Bulgarian Empire under Simeon I (called Simeon the Great in Bulgaria), who was already in a war with the Byzantines. Tomislav made a pact with the Byzantine Empire, for which he may have been rewarded by the Byzantine Emperor Romanos I Lekapenos with some form of control over the coastal cities of the Byzantine Theme of Dalmatia and with a share of the tribute collected from them.[19] After Simeon conquered the Principality of Serbia in 924, Croatia received and protected the expelled Serbs with their leader Zaharija.[25] In 926, Simeon tried to break the Croatian-Byzantine pact and afterwards conquer the weakly defended Byzantine Theme of Dalmatia,[26] sending Duke Alogobotur with a formidable army against Tomislav, but Simeon's army was defeated in the Battle of the Bosnian Highlands. After Simeon's death in 927 peace was restored between Croatia and Bulgaria with the mediation of the legates of Pope John X.[27] According to the contemporary De Administrando Imperio, the Croatian army and navy at the time could have consisted of approximately 100,000 infantry units, 60,000 cavaliers, and 80 larger (sagina) and 100 smaller warships (condura),[28] but these numbers are generally taken as a considerable exaggeration.[24] According to the palaeographic analysis of the original manuscript of De Administrando Imperio, the population of medieval Croatia was estimated at between 440,000 and 880,000 people, while the military force was most probably composed of 20,000–100,000 infantrymen and 3,000–24,000 horsemen organized into 60 allagions.[29][30]

Croatian society underwent major changes in the 10th century. Local leaders, the župani, were replaced by the retainers of the king, who took land from the previous landowners, essentially creating a feudal system. The previously free peasants became serfs and ceased being soldiers, causing the military power of Croatia to fade.

Tomislav was succeeded by Trpimir II (c. 928–935) and Krešimir I (c. 935–945), who each managed to maintain their power and keep good relations with both the Byzantine Empire and the Pope. This period, on the whole, however, is obscure. The rule of Krešimir's son Miroslav was marked by a gradual weakening of Croatia.[31] Various peripheral territories took advantage of unsettled conditions to secede.[32] Miroslav ruled for 4 years when he was killed by his ban, Pribina, during an internal power struggle. Pribina secured the throne to Michael Krešimir II (949–969), who restored order throughout most of the state. He kept particularly good relations with the Dalmatian coastal cities, he and his wife Helen donating land and churches to Zadar and Solin. Michael Krešimir's wife Helen built the Church of Saint Mary in Solin that served as the tomb of Croatian rulers. Helen died on 8 October 976 and was buried in that church, where a royal inscription on her sarcophagus was found that called her "Mother of the Kingdom".[33][34]

Michael Krešimir II was succeeded by his son Stephen Držislav (969–997), who established better relations with the Byzantine Empire and their Theme of Dalmatia. According to Historia Salonitana, Držislav received royal insignia from the Byzantines, together with the title of eparch and patricius. Also, according to this work, from the time of Držislav's reign his successors called themselves "kings of Croatia and Dalmatia". Stone panels from the altar of a 10th-century church in Knin with the inscription of Držislav, possibly when he was the heir to the throne, show that there was a precisely defined hierarchy regulating the matters of succession to the throne.[34]

As soon as Stjepan Držislav had died in 997, his three sons, Svetoslav (997–1000), Krešimir III (1000–1030), and Gojslav (1000–1020), opened a violent contest for the throne, weakening the state and allowing the Venetians under Pietro II Orseolo and the Bulgarians under Samuil to encroach on the Croatian possessions along the Adriatic. In 1000, Orseolo led the Venetian fleet into the eastern Adriatic and gradually took control of the whole of it,[35] first the islands of the Gulf of Kvarner and Zadar, then Trogir and Split, followed by a successful naval battle with the Narentines upon which he took control of Korčula and Lastovo, and claimed the title dux Dalmatiæ. Krešimir III tried to restore the Dalmatian cities and had some success until 1018, when he was defeated by Venice allied with the Lombards. The same year his kingdom briefly became a vassal of the Byzantine Empire until 1025 and the death of Basil II.[36] His son, Stjepan I (1030–1058), only went so far as to get the Narentine duke to become his vassal in 1050.

During the reign of Krešimir IV (1058–1074), the medieval Croatian kingdom reached its territorial peak. Krešimir managed to get the Byzantine Empire to confirm him as the supreme ruler of the Dalmatian cities, i.e., over the Theme of Dalmatia, excluding the theme of Ragusa and the Duchy of Durazzo.[37] He also allowed the Roman curia to become more involved in the religious affairs of Croatia, which consolidated his power but disrupted his rule over the Glagolitic clergy in parts of Istria after 1060. Croatia under Krešimir IV was composed of twelve counties and was slightly larger than in Tomislav's time. It included the closest southern Dalmatian duchy of Pagania, and its influence extended over Zahumlje, Travunia, and Duklja. The župans (heads of counties) had their own private armies. The names of court titles in their vernacular form appear for the first time during his reign, such as vratar ("door-keeper") Jurina, postelnik ("chamberlain") and so on.[38] The Roman Catholic Church reforms, which imposed a ban on the use of Slavonic liturgy and introduced Latin as obligatory, were confirmed by Pope Alexander II in 1063. This led to a rebellion in the kingdom by the counter-reform camp, primarily in the Kvarner region. While King Krešimir IV sided with the Pope, expecting a victory of the pro-Latin clergy, support for the counter-reform clergy was provided by Antipope Honorius II. The rebellion was led by a priest named Vulfo on the island of Krk. Although the rebels were quickly suppressed, Slavonic liturgy held out in the Kvarner region, as well as the use of Glagolitic script.[39]

However, in 1072, Krešimir assisted the Bulgarian and Serb uprising against their Byzantine masters. The Byzantines retaliated in 1074 by sending the Norman count Amico of Giovinazzo to besiege Rab. They failed to capture the island, but did manage to capture the king himself, and the Croatians were then forced to settle and give away Split, Trogir, Zadar, Biograd, and Nin to the Normans. In 1075, Venice expelled the Normans and secured the cities for itself. The end of Krešimir IV in 1074 also marked the de facto end of the Trpimirović dynasty, which had ruled the Croatian lands for over two centuries.

Krešimir was succeeded by Demetrius Zvonimir (1075–1089) of the Svetoslavić branch of the House of Trpimirović. He was previously a ban in Slavonia in the service of Peter Krešimir IV and later the Duke of Croatia. He gained the title of king with the support of Pope Gregory VII and was crowned as King of Croatia in Solin on 8 October 1075. Zvonimir aided the Normans under Robert Guiscard in their struggle against the Byzantine Empire and Venice between 1081 and 1085. Zvonimir helped to transport their troops through the Strait of Otranto and to occupy the city of Dyrrhachion. His troops assisted the Normans in many battles along the Albanian and Greek coast. Due to this, in 1085, the Byzantines transferred their rights in Dalmatia to Venice.

Zvonimir's kinghood is carved in stone on the Baška Tablet, preserved to this day as one of the oldest written Croatian texts, kept in the archæological museum in Zagreb. Zvonimir's reign is remembered as a peaceful and prosperous time, during which the connection of Croats with the Holy See was further affirmed, so much so that Catholicism would remain among Croats until the present day. In this time the noble titles in Croatia were made analogous to those used in other parts of Europe at the time, with comes and baron used for the župani and the royal court nobles, and vlastelin for the noblemen. The Croatian state was edging closer to western Europe and further from the east. Demetrius Zvonimir married Helen of Hungary in 1063. Queen Helen was a Hungarian princess, the daughter of King Béla I of the Hungarian Árpád dynasty, and was the sister of the future Hungarian King Ladislaus I. Zvonimir and Helen had a son, Radovan, who died in his late teens or early twenties. King Demetrius Zvonimir died in 1089. The exact circumstances of his death are unknown. According to a later, likely unsubstantiated legend, King Zvonimir was killed during a revolt in 1089.

There was no permanent state capital, as the royal residence varied from one ruler to another; five cities in total reportedly obtained the title of a royal seat: Nin (Krešimir IV), Biograd (Stephen Držislav, Krešimir IV), Knin (Zvonimir, Petar Snačić), Šibenik (Krešimir IV), and Solin (Krešimir II).[40]

In 1102, after the succession crisis, the crown passed into the hands of the Árpád dynasty, with the crowning of King Coloman of Hungary as "King of Croatia and Dalmatia" in Biograd. The precise terms of the union between the two realms became a matter of dispute in the 19th century.[9] The two kingdoms were united under the Árpád dynasty either by the choice of the Croatian nobility or by Hungarian force.[55] Croatian historians hold that the union was a personal one in the form of a shared king, a view also accepted by a number of Hungarian historians,[6][12][45][49][56][57] while Serbian and Hungarian nationalist historians preferred to see it as a form of annexation.[8][9][58] The claim of a Hungarian occupation was made in the 19th century during the Hungarian national reawakening.[58] Thus in older Hungarian historiography Coloman's coronation in Biograd was a subject of dispute and their stance was that Croatia was conquered. Although these kinds of claims can also be found today, since the Croatian-Hungarian tensions are gone, it has generally been accepted that Coloman was crowned in Biograd as king.[59] Today, Hungarian legal historians hold that the relationship of Hungary with the area of Croatia and Dalmatia in the period till 1526 and the death of Louis II was most similar to a personal union,[12][60] resembling the relationship of Scotland to England.[61][62]

According to the Worldmark Encyclopedia of Nations and the Grand Larousse encyclopédique, Croatia entered a personal union with Hungary in 1102, which remained the basis of the Hungarian-Croatian relationship until 1918,[3][63] while Encyclopædia Britannica specified the union as a dynastic one.[52] According to the research of the Library of Congress, Coloman crushed opposition after the death of Ladislaus I and won the crown of Dalmatia and Croatia in 1102, thus forging a link between the Croatian and Hungarian crowns that lasted until the end of World War I.[64] Hungarian culture permeated northern Croatia, the Croatian-Hungarian border shifted often, and at times Hungary treated Croatia as a vassal state. Croatia had its own local governor, or Ban; a privileged landowning nobility; and an assembly of nobles, the Sabor.[64] According to some historians, Croatia became part of Hungary in the late 11th and early 12th century,[65] yet the actual nature of the relationship is difficult to define.[58] Sometimes Croatia acted as an independent agent and at other times as a vassal of Hungary.[58] However, Croatia retained a large degree of internal independence.[58] The degree of Croatian autonomy fluctuated throughout the centuries as did its borders.[10]

The alleged agreement called Pacta conventa (English: Agreed accords) or Qualiter (first word of the text) is today viewed as a 14th-century forgery by most modern Croatian historians. According to the document King Coloman and the twelve heads of the Croatian nobles made an agreement, in which Coloman recognised their autonomy and specific privileges. Although it is not an authentic document from 1102, nonetheless there was at least a non-written agreement that regulated the relations between Hungary and Croatia in approximately the same way,[45][52] while the content of the alleged agreement is concordant with the reality of rule in Croatia in more than one respect.[54]

The official entering of Croatia into a personal union with Hungary, later becoming part of the Lands of the Crown of St. Stephen,[66] had several important consequences. Institutions of separate Croatian statehood were maintained with the Sabor (parliament) and the ban (viceroy)[52] in the name of the king. A single ban governed all Croatian provinces until 1225, when the authority was split between one ban of the whole of Slavonia and one ban of Croatia and Dalmatia. The positions were intermittently held by the same person after 1345, and officially merged back into one by 1476.
