Territory.
The municipality of Codroipo extends for 75 km² across the Veneto-Friuli Plain, on the eastern bank of the Tagliamento river, from which it lies about 6 km away, on the border between Upper and Lower Friuli, in the area of resurgences of Middle Friuli, halfway between the cities of Udine and Pordenone, both about 27 km away.
The area is affected by the phenomenon of resurgences, which contributes to the proliferation of streams, irrigation channels and aquatic environments such as lakes and ponds. The persistent action of man has today profoundly changed its nature as a function of monoculture agriculture. However, some areas have been preserved: the Parco delle Risorgive di Codroipo, located south of the town, near the sports centre, offers an example of what the environment was in pre-industrial times.
History.
While being recognised as a hill-fort area since the Bronze Age, the settlement acquired relevance during the Roman era, between the first and second century BCE. . 
The foundation of the original colony in Aquileia dates back to 181 BCE, with a strategic role as crossroads for Res Publica merchants and soldiers. The ancient name "Quadruvium" (then "Quadrupio") is supposedly derived from the four main "contrade" ("quadrivio"), which converged thanks to the meeting of two prominent Roman roads: the first , the Via Postumia, linked Aquileia to Genoa, while the second, the Via Julia Augusta, led from Mestre all the way to Norico and they both merged in Udine. Codroipo was a pagus in the municipality of Aquileia until its fall to Attila in 452. Some other roads were the Via Annietta and the Via Crescenzia, which linked Concordia to Gemona and Majano to Lignano Sabbiadoro respectively.
Its history is largely shared with that of Friuli in general and was part of the Republic of Venice. In 1797 the Treaty of Campoformio was signed in a nearby villa owned by Ludovico Manin, marking Napoleon Bonaparte's victory, the fall of the First Coalition, and the cession of Friuli to Austria.
In the final days of World War I, it was occupied by the 332nd Infantry Regiment, the only American military unit in the Italian theater.

During the 1920s, the extensive cultivation of tobacco spread, and in 1938 a factory was built in the form of a cooperative, for the drying and processing of tobacco.
After World War II, a period of gradual expansion of commercial activities and services began. In particular, during the 1980s, the phenomenon of small family businesses typical of North-East Italy, which witnessed a progressive spread of well-being across the territory accompanied by relative demographic growth net of a parallel reduction of military personnel presence since the 1990s.
The most important companies operate in the construction, thermo-electric, furniture, organ building and viticulture sectors.
