County of Gorizia

Meinhard's descendant Count Meinhard III of Gorizia, a follower of the Hohenstaufen emperor Frederick II, upon the extinction of the ducal House of Babenberg was appointed administrator of Styria in 1248. He campaigned the adjacent Duchy of Carinthia but was defeated by the troops of Duke Bernhard von Spanheim and his son Archbishop Philip of Salzburg at Greifenburg in 1252. Nevertheless, the county reached the apex of its power, when Meinhard III inherited County of Tyrol (as Meinhard I) from his father-in-law Count Albert IV one year later.

Gorizia Castle

After Count Meinhard III had died in 1258, his sons at first ruled jointly until in 1271 they divided their heritage: While the elder Meinhard IV took the comital Tyrolean lands west of the Puster Valley, his brother Albert retained the Meinhardiner ancestral lands around Lienz and Gorizia. After his death, the County of Gorizia was again partitioned among his sons into the "inner county" at Gorizia, ruled by Henry III, and the "outer county" around Lienz und Albert II. When Count Henry III was assassinated in 1323, the Gorizia lands were shattered into four countries. The Counts of Gorizia temporarily controlled the Italian March of Treviso (Marca Trevigiana) and the remains of the Istrian march around Pazin (Mitterburg), which Count Albert III of Görz bequeathed to the House of Habsburg in 1365.

In 1365 Count Meinhard VI of Görz was granted the princely title by the Luxembourg emperor Charles IV, the county was thereon called Gefürstete Grafschaft Görz. The Meinhardiner nevertheless suffered a steep decline under their powerful neighbours, the Austrian lands of the Habsburg dynasty and the Republic of Venice. After the Habsburgs had acquired the Carinthian duchy with the March of Carniola in 1335 and the County of Tyrol in 1363, the remaining Gorizia lands of Lienz were a thorn in their side, separating the dynasty's "hereditary lands". Venice had conquered the former Patriarchate territories in Friuli, which were incorporated into the Domini di Terraferma by 1434. The Council of Ten strived for the adjacent "inner county" lands around Gorizia up to the Venetian Stato da Màr territories in Istria. Due to the pressure, the Gorizia counts took their residence at Bruck Castle in Lienz.

In 1429 the county was reunited under the single rule of Count Henry VI. His son, the last count Leonhard, died in 1500 and despite claims raised by Venice, according to a contract of inheritance the county fell to the Habsburg emperor Maximilian I.

While the Lienz area was administrated with the Tyrolean crown land, the "inner county" of Gorizia remained an Imperial State of the Holy Roman Empire ruled by the Inner Austrian Archdukes as part of the Austrian Circle, governed by a capitano. Its territory included the Isonzo Valley down to Aquileia, the area of Cormons and Duino, and the former Venetian fortress of Gradisca, which was conquered by Imperial troops in 1511. Monfalcone formed a Venetian exclave in the county from 1420 to 1797. In 1647 Emperor Ferdinand III separated the "Principality of Gradisca" from Gorizia for his courtier Johann Anton von Eggenberg, until in 1747 both were again merged to form the Princely County of Gorizia and Gradisca, a crown land of the Habsburg Monarchy.
