In 1815, the Congress of Vienna confirmed the union of Veneto, which Central-West Friuli was part of, with Lombardy (previously divided between Austrian Empire and Venetian Republic), to constitute the Kingdom of Lombardy-Venetia.
Eastern Friuli was not included in the puppet state.
In 1838, the District of Portogruaro was removed from the Province of the Friuli due to the Austrians' wishes and assigned to the Province of Venice.
Portogruaro was for long time part of Friuli, even under Venetian Republic, and Friulian language was spoken in the area.
In 1866, central Friuli (today's province of Udine) and western Friuli (today's province of Pordenone) were annexed by Italy together with Veneto after the Third Italian War of Independence, while eastern Friuli (County of Gorizia and Gradisca) remained under Austria until the end of World War I.
The Ethnographic map of Karl von Czoernig-Czernhausen, issued by the k. u. k. Administration of Statistics in 1855, recorded a total of 401,357 Friulians living in the Austrian Empire.
The majority of Friulians (351,805) lived in that part of Friuli that belonged to the Kingdom of Lombardy-Venetia, the others (49.552) in the Friulian parts of the Austrian Küstenland.
Friulians were registered as their own category separate from Italians.

During World War I, Friuli was a theater of battle that had serious consequences for the civilian population, specifically the Battle of Caporetto.
