What happened
After Ottoman forces under Selim II completed the conquest of Venetian Cyprus in 1570, a coalition of Catholic states called the Holy League, assembled under Pope Pius V and led by Spain and Venice, moved to confront the Ottoman fleet. The two navies met on 7 October 1571 in the Gulf of Patras near Lepanto, in the largest galley battle in Mediterranean history. The Holy League destroyed the Ottoman fleet, ending what had been unchallenged Ottoman naval dominance in the eastern Mediterranean for decades.
Why it matters
The sultan rebuilt his fleet within a year and Ottoman forces kept Cyprus, so the defeat changed little on the map. It broke something less tangible instead: the assumption in Christian Europe that Ottoman naval power was unstoppable, and it gave the Holy League states a symbolic victory they celebrated for generations. The Ottomans made only one further Mediterranean conquest afterward, taking Crete in 1669, and Ottoman naval power declined relative to European fleets from that point on.
How we know
World History Encyclopedia's overview of Ottoman battles and conquests and its general history of the empire both place Lepanto in October 1571 in the Gulf of Patras, tying the defeat to the empire's declining ability to fund and modernize its navy from the 17th century onward.
