The Republic of Venice or Venetian Republic, traditionally known as La Serenissima, was a sovereign state and maritime republic in parts of the present-day Italian Republic, Istria and Dalmatia that existed for 1,100 years from 697 until 1797. Centered on the lagoon communities of the prosperous city of Venice, it incorporated numerous overseas possessions in modern Croatia, Slovenia, Montenegro, Greece, Albania and Cyprus. The republic grew into a trading power during the Middle Ages and strengthened this position during the Renaissance. Most citizens spoke the Venetian language, although publishing in Italian became the norm during the Renaissance.

Venetian, wider Venetian or Venetan is a Romance language spoken natively in the northeast of Italy, mostly in Veneto, where most of the five million inhabitants can understand it. It is sometimes spoken and often well understood outside Veneto: in Trentino, Friuli, the Julian March, Istria, and some towns of Slovenia, Dalmatia (Croatia) and Bay of Kotor (Montenegro) by a surviving autochthonous Venetian population, and in Argentina, Australia, Brazil, Canada, Mexico, the United States and the United Kingdom by Venetians in the diaspora.
