The March of Istria (or Margraviate of Istria // ) was originally a Carolingian frontier march covering the Istrian peninsula and surrounding territory conquered by Charlemagne's son Pepin of Italy in 789. After 1364, it was the name of the Istrian province of the Habsburg Monarchy, the Austrian Empire and Austria-Hungary.
The settlement area of the ancient Histri tribes had been conquered by the Roman Empire until 178 BC and was incorporated into the northeastern Venetia et Histria region of the Italia province under Emperor Augustus. Upon the Decline of the Roman Empire and the Migration Period, the Lombards under King Alboin from 568 onwards conquered Venetia, where they established the Duchy of Friuli, part of their Kingdom of Italy. The Istrian peninsula remained under Byzantine (Eastern Roman) influence, while South Slavic tribes (Croatians and Slovenes) settled in the east and north.
Aistulf, King of the Lombards from 749, attacked the remaining Byzantine territories in Italy and even threatened the Byzantine Papacy in Rome. As Pope Zachary expected no help from Constantinople, he forged an alliance with Pepin the Short, the powerful Mayor of the Palace of the Frankish kingdom north of the Alps, whom he legitimized as King of the Franks. In 755, Pepin invaded Italy and forced Aistulf under Frankish suzerainty. Pepin's son Charlemagne in 773/774 finally incorporated the Italian kingdom into the Carolingian Empire.
Charlemagne at first attached the Istrian peninsula to the Lombard Duchy of Friuli, part of the Carolingian Kingdom of Italy under his son Pepin. Though officially a duchy, Friuli de facto was a march with a merely titular ducal dignity, from 776 ruled by Frankish appointees.
An Istrian margraviate itself first emerged following the death of Duke Eric of Friuli in the 799 Siege of Trsat on the Frankish border with Littoral Croatia. Istria was enfeoffed to the Frankish count Hunfrid, who also bore the title of a dux Foroiulanus. The original Carolingian march stretched from the Julian Alps and the Kras Plateau down to the Gulf of Kvarner. It was one of three marches, along with Friuli and Carantania, guarding Italy from the Avars, Slavs, and Magyars successively. In the first decade of the 9th century, Istria was ruled by one Duke John, nominally according to its ancient Byzantine customs, but in fact as a Frankish vassal. The region then had nine cities, Trieste foremost among them.
After King Pepin had made several attempts to conquer Venice on the Adriatic coast, his father Emperor Charlemagne under the 812 Treaty of Aix-la-Chapelle finally recognised the formal Byzantine control over the city along with Istria, at least its western coast. After this, it falls into obscurity, but perhaps the Byzantines never succeeded in re-establishing their government in the returned territories, if they were actually handed over. The remaining parts of Istria were probably eventually just re-integrated into the Carolingian duchy of Friuli.
When after the deposition of the last Friulian duke Baldric, Emperor Louis the Pious at the 829 Reichstag in Worms divided his vast duchy into four marches. Istria with the March of Friuli was ruled from Aquileia by Margrave Eberhard and his Unruoching descendants. It became part of Middle Francia after the 843 Treaty of Verdun, and was allotted to Emperor Louis II's Italian kingdom in 855. The Unruoching margrave Berengar of Friuli even succeeded Charles the Fat as King of Italy in 888.
After the German king Otto I had campaigned northern Italy under Berengar's grandson King Berengar II, in 952 he merged Friuli into the vast March of Verona, which he granted it to his brother Duke Henry I of Bavaria, who already controlled the adjacent Carinthian and Carniolan marches. After the deposition of Henry's son and successor Duke Henry the Wrangler in 976, Emperor Otto II separated Carinthia from the Bavaria as a duchy in its own right, ruled by Duke Henry the Younger who was also given suzerainty over the southeastern Bavarian marches, including Verona, Istria, Carniola and Styria.
There appear counts of Istria late in the 10th century, but Istria together with the March of Carniola was separated from the Carinthian duchy in 1040, when both were bestowed on the Thuringian Count Poppo of Weimar, heir by marriage to the last known Friulian margrave Weriand (Werigand (Friaul)). The Carniolan margraves gradually acquired the northeastern territories of the peninsula, while the western and southern coast was gradually occupied by the Republic of Venice. The German king Henry IV nominally assigned the remaining march to the Patriarchate of Aquileia, the margravial title and the Istrian territories were however retained by Carniola. In 1173 the Hohenstaufen Emperor Frederick Barbarossa enfeoffed the Bavarian noble House of Andechs, who attached Istria to their Duchy of Merania. Aquileia regained Istria in 1209, when the Andechs margraves were banned due to alleged entanglement in the assassination of the German king, Frederick Barbarossa's son Philip of Swabia.
By mid-century most of the Istrian coast had been conquered by Venice. The patriarchs had ceased appointing margraves and had given the remaining interior of the peninsula into the direct control of their Vogt officials, the Counts of Görz. The Görz territories were finally acquired by the Habsburg archdukes of Austria in 1374, who since 1335 had held the Carniolan march. In 1382 they also gained control over the City of Trieste.

After the secular territory of the Patriarchs of Aquileia had been completely conquered by Venice in 1420, most of Istria belonged to La Serenissima. The Austrian House of Habsburg only held a small territory in the interior of the peninsula around Pazin (Mitterburg), which it administered from its Carniolan duchy. The Habsburg rulers nevertheless added the title of a "Margrave of Istria" to their other titles, persisting until the dissolution of the Austro-Hungarian monarchy in 1918.
Venetian Istria fell to the Habsburg Monarchy (the Austrian Empire after 1804) according to the 1797 Treaty of Campo Formio but was subsequently seized by Napoleon in the 1805 Peace of Pressburg, forming part of the Kingdom of Italy. It was then incorporated into the French Empire as part of the Illyrian Provinces in 1809. In 1815, after Napoleon had been defeated, the territory was returned to Austria as part of the Kingdom of Illyria by the 1815 Congress of Vienna.
After the partition of the Illyrian kingdom in 1849, the Margravate of Istria became a subdivision of the Austrian Littoral crown land. It received considerable autonomy as a crown land in its own right with the establishment of the Diet of Istria at Parenzo by the 1861 February Patent.
The title was held afterwards by the Habsburg monarch and the "Margrave of Istria" was included in the grand title of the Emperor of Austria.
The Duchy of Carinthia was a duchy located in southern Austria and parts of northern Slovenia. It was separated from the Duchy of Bavaria in 976, and was the first newly created Imperial State after the original German stem duchies.
The Duchy of Carniola was an imperial estate of the Holy Roman Empire, established under Habsburg rule on the territory of the former East Frankish March of Carniola in 1364. A hereditary land of the Habsburg Monarchy, it became a constituent land of the Austrian Empire in 1804 and part of the Kingdom of Illyria until 1849. A separate crown land from 1849, it was incorporated into the Cisleithanian territories of Austria-Hungary from 1867 until the state's dissolution in 1918. Its capital was Ljubljana.
Goriška is a historical region in western Slovenia on the border with Italy. It comprises the northern part of the wider traditional region of the Slovenian Littoral (Primorska). The name Goriška is an adjective referring to the city of Gorizia, its historical and cultural centre.
Gračišće is a village and municipality of Istria County in Croatia.
The County of Gorizia, from 1365 Princely County of Gorizia, was a State of the Holy Roman Empire. Originally mediate Vogts of the Patriarchs of Aquileia, the Counts of Gorizia (Meinhardiner) ruled over several fiefs in the area of Lienz and in the Friuli region of northeastern Italy with their residence at Gorizia (Görz).
Berthold IV, a member of the House of Andechs, was Margrave of Istria and Carniola. By about 1180/82 he assumed the title of Duke of Merania, referring to the Adriatic seacoast of Kvarner which his ancestors had conquered in the 1060s and annexed to Istria and Carniola.
The Duchy of Friuli was a Lombard duchy in present-day Friuli, the first to be established after the conquest of the Italian peninsula in 568. It was one of the largest domains in Langobardia Major and an important buffer between the Lombard kingdom and the Slavs, Avars, and the Byzantine Empire. The original chief city in the province was Roman Aquileia, but the Lombard capital of Friuli was Forum Julii, modern Cividale.
The Marchof Carniola was a southeastern state of the Holy Roman Empire in the High Middle Ages, the predecessor of the Duchy of Carniola. It corresponded roughly to the central Carniolan region of present-day Slovenia. At the time of its creation, the march served as a frontier defense against the Kingdoms of Hungary and Croatia.
The March of Verona and Aquileia was a vast march of the Holy Roman Empire in northeastern Italy during the Middle Ages, centered on the cities of Verona and Aquileia. Seized by King Otto I of Germany in 952, it was held by the Dukes of Bavaria; from 976 in personal union with the Duchy of Carinthia. The margravial regime ended with the advent of the Lombard League in 1167.
The March of Friuli was a Carolingian frontier march, established in 776 as the continuation of the Lombard Duchy of Friuli, established against the Slavs and Avars. It was ceded to the Duchy of Bavaria as the March of Verona in 952. Its territory comprised parts of modern-day Italy, Slovenia and Croatia.
Poppo I, Count of Weimar-Orlamünde, was margrave of Istria from 1012 and of Carniola from 1040 to his death.
Sponheim or Spanheim was a medieval German noble family, which originated in Rhenish Franconia. They were immediate Counts of Sponheim until 1437 and Dukes of Carinthia from 1122 until 1269. A cadet branch ruled in the Imperial County of Ortenburg-Neuortenburg until 1806.
The March of Carinthia was a frontier district (march) of the Carolingian Empire created in 889. Before it was a march, it had been a principality or duchy ruled by native-born Slavic princes at first independently and then under Bavarian and subsequently Frankish suzerainty. The realm was divided into counties which, after the succession of the Carinthian duke to the East Frankish throne, were united in the hands of a single authority. When the march of Carinthia was raised into a Duchy in 976, a new Carinthian march was created. It became the later March of Styria.
The House of Andechs was a feudal line of German princes in the 12th and 13th century. The Counts of Dießen-Andechs obtained territories in northern Dalmatia on the Adriatic seacoast, where they became Margraves of Istria and ultimately dukes of a short-lived imperial state named Merania from 1180 to 1248. They were also self-styled lords of Carniola.
Berthold III, a member of the Bavarian House of Andechs, was Margrave of Istria from 1173 until his death.
The Windic March was a medieval frontier march of the Holy Roman Empire, roughly corresponding to the Lower Carniola (Dolenjska) region in present-day Slovenia. In Slovenian historiography, it is known as Slovene March.
The Patria del Friuli was the territory under the temporal rule of the Patriarch of Aquileia and one of the ecclesiastical states of the Holy Roman Empire. In 1420, the Republic of Venice acquired it, but it continued to be ruled for some time under its own laws and customs.
Sophia of Hungary, a member of the royal Árpád dynasty, was a Margravine of Istria and Carniola from about 1062 until 1070, by her first marriage with Margrave Ulric I, as well as Duchess of Saxony from 1072 until her death, by her second marriage with Duke Magnus Billung.
Matilda of Andechs was a daughter of Margrave Berthold I of Istria and his first wife, Hedwig of Dachau-Wittelsbach, daughter of the Bavarian Count palatine Otto IV of Scheyern.
The Duchy of Merania was a fiefdom of the Holy Roman Empire from 1152 until 1248. The dukes of Merania were recognised as princes of the Empire enjoying imperial immediacy at a time when these concepts were just coming into use to distinguish the highest ranks of imperial nobility.
