The March of Istria (or Margraviate of Istria

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 Istrian province of the Habsburg monarchy, the Austrian Empire and Austria-Hungary

History

The settlement area of the ancient

Croatians and Slovenes
) settled in the east and north.

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
.

Carolingian march

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

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

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.

Imperial march

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 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

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

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
.

Habsburg Margraviate

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

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.
