What is the history of Venice?

Venice was originally founded in the 6th century by immigrants who came to the island to escape the war. In the middle of the 9th century, it became a city-state center independent of Byzantium. Venice's unique geographical location has gradually become a crossroads connecting East and West trade routes since the13rd century. By the middle of14th century, Venice had become the most powerful and richest maritime country in Italy, with 3,000 merchant ships and nearly 20,000 crew members, and was known as "the capital of countries along the Adriatic Sea". It was not until16th century that Columbus discovered the New World that its economic status began to decline gradually, and finally it was merged into the Kingdom of Italy in 1866. Venice gradually lost its powerful dominance in the late18th century. In the Napoleonic Wars, Venice finally succumbed to Bonaparte's iron hoof. 1866, Venice returned to Italian rule. 1930, Mussolini ordered the construction of a passage connecting the mainland and Venice.
