The Stato da Màr or Domini da Mar (lit. 'State of the Sea' or 'Domains of the Sea'), sometimes described as a maritime empire or overseas empire, comprised the maritime and overseas territories controlled by the Republic of Venice from approximately 1000 until 1797. At various points, these territories included parts of present-day Italy, Slovenia, Croatia, Montenegro, Albania, and Greece—notably Istria, Dalmatia, the Ionian Islands, the Peloponnese, Crete, the Cyclades, Euboea, and Cyprus.
It was one of the three subdivisions of the Republic of Venice's possessions, the other two being the Dogado, i.e. Venice proper, and the Domini di Terraferma in northern Italy.
