The Republic of Venice (Repùbrega Vèneta; Repubblica di Venezia) was a sovereign state and maritime republic in Northeast Italy, which existed for a millennium between the 8th century and 1797. It was based in the lagoon communities of the historically prosperous city of Venice, and was a leading European economic and trading power during the Middle Ages and the Renaissance, the most successful of Italy's maritime republics. By the late Middle Ages, it held significant territories in the mainland of northern Italy, known as the Domini di Terraferma, along with most of the Dalmatian coast on the other side of the Adriatic Sea, and Crete and numerous small colonies around the Mediterranean Sea, together known as the Stato da Màr. A slow political and economic decline had begun by around 1500, and by the 18th century the city of Venice largely depended on the tourist trade, as it still does, and the Stato da Màr was largely lost. Although no surviving historical records deal directly with the founding of Venice, the history of the Republic of Venice traditionally begins with the foundation of the city at Noon on Friday, 25 March, AD 421, by authorities from Padua, to establish a trading-post in that region of northern Italy. The founding of the Venetian republic is also said to have been marked at that same event with the founding of the church of St. James. However, the church (believed to be Saint Giacomo di Rialto) dates back no further than the eleventh century, at the earliest, or the mid-twelfth century, at the latest. The 11th century Chronicon Altinate also dates the first settlement in that region, Rivo Alto ("High Shore", later Rialto), to the dedication of that same church (i.e., San Giacometo on the bank of the current Grand Canal). According to tradition, the original population of the region consisted of refugees—from nearby Roman cities such as Padua, Aquileia, Treviso, Altino, and Concordia (modern Concordia Sagittaria), as well as from the undefended countryside—who were fleeing successive waves of Hun and Germanic invasions from the mid-second to mid-fifth centuries.
