Venice, capital of Italy’s Veneto region, grew from lagoon refuges into the powerful Republic of Venice, a maritime and financial superpower that dominated Mediterranean trade, crusading fleets, and luxury arts for centuries. Ruled by an oligarchic republic led by an elected doge, it built a sea empire, controlled vital routes, and pioneered printing, music, and painting. Decline followed plagues, Ottoman wars, and the shift of global trade to Atlantic routes, and the republic fell to Napoleon in 1797. Today Venice is a UNESCO-listed, car-free city famed for beauty and festivals but threatened by overtourism, subsidence, flooding, and climate-driven sea-level rise.
