Isonzo in the context of "Julian Alps"

The Dogado, or the Duchy of Venice, was the metropolitan territory of the Republic of Venice, headed by the Doge, traditionally from 697, and up to 1797. It comprised the city of Venice and the narrow coastal strip from Loreo to Grado, though these borders later extended from Goro to the south, the Polesine and the Padovano to the west, the Trevisano and Friuli to the north and the mouth of the Isonzo to the east.

Apart from Venice, the capital and in practice a city-state of its own, the Dogado was subdivided in nine districts starting at the north: Grado, Caorle, Torcello, Murano, Malamocco, Chioggia, Loreo, Cavarzere and Gambarare (in Mira). In lieu of the earlier tribunes (elected by the people) and gastalds (corresponding with the Doge), during the Republic each district was led by a patrician with the title of podestà, with the exception of Grado, headed by a Count.

The Venetian Plain, or Venetian-Friulian Plain (Italian: Pianura Veneta or Pianura Veneto-friulana) is a major geographical feature of Italy. It extends approximately from the River Adige to the River Isonzo, in a southwest-to-northeast direction, including almost all the flatlands of Veneto and Friuli. The plain is divided into high and low plains with the high plain located between Brenta and Piave rivers. It is not properly related to the Po River basin, but it is often considered as part of the Po Valley since the flatlands of Veneto and Friuli do not drain into the Po, but they effectively combine into an unbroken plain. Sometimes, instead of the River Adige, the Euganei Hills and Berici Hills are considered to be its western border.

Grado (Venetian: Gravo; Friulian: Grau; Slovene: Gradež; Latin: Gradus) is a town and comune (municipality) of 8,064 residents in the Regional decentralization entity of Gorizia in the north-eastern Italian region of Friuli-Venezia Giulia, located on an island and adjacent peninsula of the Adriatic Sea between Venice and Trieste. The territory of the municipality of Grado extends between the mouth of the Isonzo and the Adriatic Sea and the Grado Lagoon, and covers an area of about 90 square kilometers between Porto Buso and Fossalon. Characteristic of the lagoon is the presence of the casoni, which are simple houses with thatched roof used in the past by the fishermen of Grado, who remained in the lagoon for a long time, returning to the island of Grado only during the colder period of the year.

Once mainly a fishing centre, today it is a popular tourist destination, known commonly as L'Isola del Sole ("The Island of the Sun"). It is also famous because it is a spa town; from 1873 a maritime hospice for children called Ospizio Marino wanted by the doctor Giuseppe Barellai was established on the island, because the climate and the environment of the island are a good place for the treatment of some childhood diseases. Subsequently, Grado was the chosen destination for marine thermal treatments, especially by the Austrian population. Together with Marano Lagunare, it is the centre of the Marano-Grado Lagoon, which is famous for its uncontaminated nature. Grado is the birthplace of Biagio Marin, a poet who sang about the island in the local Venetian dialect.

The Battle of Caporetto (also known as the Twelfth Battle of the Isonzo, the Battle of Kobarid or the Battle of Karfreit) took place on the Isonzo front of World War I.

The battle was fought between the Kingdom of Italy and the Central Powers and took place from 24 October to 19 November 1917, near the town of Kobarid (now in north-western Slovenia, then part of the Austrian Littoral), and near the river Isonzo. The battle was named after the Italian name of the town (also known as Karfreit in German).
