Throughout its history, several feudal lords contended for Orsago until it finally became property of the Da Camino family who controlled the area until circa 1350. It then passed into the hands of the Bishop of Aquilei, who named Francesco Sbrojavacca its seignior. Aquilei’s bishop managed these territories from an ecclesiastic point of view, until the beginning of the nineteenth century.
Conquered by the Carraresi, the Lords of Padua, Orsago remained in the dynasty’s possession for less than ten years, before it permanently became the property of Venice. During four centuries of Venetian domination, Orsago experienced a long period of peace and relative prosperity which was temporarily interrupted by a dramatic famine that struck the area between the fifteen and sixteenth centuries. The municipality’s lovely churches and villas give the territory an aristocratic feel, bearing witness to the appreciation Venetian patricians had for the area.
Via Ongaresca and other streets leading to the municipality’s capital morphed into important commercial routes. Public works were organized in order to consolidate them and readjust the area’s hydraulics system which also involved the Palù district. The reclamation of Palù was completed during the Kingdom of Italy. Unfortunately, widespread poverty and malnutrition, which the country’s new leaders faced with inadequate means, forced many inhabitants to opt for voluntary exile and immigrate to South America. Several local entrepreneurs worked to counter this phenomenon by founding silk work farms and establishing a local spinning mill, in addition to creating the ‘Cassa Rurale e Artigiana’ bank in 1895. The municipality’s industrialization process slowed during World War I, gaining momentum between the two great wars and after the end of World War II.
Currently, Orsago’s population is dedicated to cultivating vineyards and grain. Many of its inhabitants also work wood or metal, either hand-crafted or on an industrial level. Other important industries include textiles, services, transportation and the confectionary industry.
