Editing Adria (section)

===Medieval and modern age===
At the time of the fall of the [[Western Roman Empire]], the port of Adria had lost most of its importance. It finally declined after the total change of the local hydrography in 589, following the catastrophic flood documented by [[Paul the Deacon]],<ref>Paolo Mozzi ''et al.'', "Long-term drivers and impacts of abrupt river changes in managed lowlands of the Adige river and northern Po delta (Northern Italy)", ''Quaternary International '', October 2018.</ref> and Adria became a fief of the [[archdiocese of Ravenna]].

After a period as an independent commune, it was a possession of the [[House of Este|Este]] of [[Ferrara]] and, in the 16th century, of the [[Republic of Venice]]. At that time Adria was a small village surrounded by [[malaria]]-plagued marshes. It recovered its importance when [[Polesine]] was reclaimed in the same century.

During the [[Napoleonic Wars]] it was first under France, then under [[Austria]], to which it was assigned in 1815 after the [[Congress of Vienna]], as part of [[Lombardy-Venetia]].
