In 1684, soon after the Turkish defeat in the siege of Vienna, Venice entered an alliance, the Holy League, with Austria against the Ottomans; Russia was later included. At the beginning of the Morean War (1684–99) Francesco Morosini occupied the island of Levkas and set out to recapture the Greek ports. Between June 1685, when he landed at Corone, and August, when he occupied Patras, Lepanto and Corinth, he secured the Peloponnese for Venice. In September, during the attack on Athens, a Venetian cannon blew up the Parthenon. Venetian possessions were greatly increased in Dalmatia too, although the attempt to regain Negropont in 1688 was a failure. Morosini's successors failed to obtain lasting results in the next years, although large fleets were sent out, and in spite of some brilliant victories — at Mitylene in 1695, Andros in 1697 and the Dardanelles in 1698. The Treaty of Karlowitz (1699) favoured Austria and Russia more than Venice, which failed to regain its bases in the Mediterranean taken by the Turks in the previous two centuries, in spite of its conquests.
