Command of the sea has decided the fate of empires as surely as any land campaign. From the oar-driven triremes that met in the narrows off Athens to the aircraft carriers that fought a battle over the horizon in the Pacific, these are seven sea battles that changed history. Each one has its full story a click away.
Salamis, 480 BC. In the narrow straits the Greek triremes turned the vast Persian fleet's numbers against it and saved Greece from conquest.

Actium, 31 BC. Off the coast of Greece, Octavian's admiral Agrippa broke the fleet of Antony and Cleopatra, and the Roman Empire was born from the wreckage.
Lepanto, 1571. The Holy League smashed the Ottoman fleet in the last great battle of oar-driven galleys, a turning point for the Mediterranean.

Trafalgar, 1805. Nelson broke the combined French and Spanish fleet and lost his life in the hour of victory, winning Britain command of the seas for a century.
Tsushima, 1905. Admiral Togo's Japanese fleet annihilated the Russian Baltic Fleet, which had sailed some 18,000 miles over seven months to reach the war, in one of the most decisive naval battles ever fought. It forced Russia to make peace and announced Japan as a modern great power.

Midway, 1942. American carrier aircraft sank four Japanese carriers, three of them in a matter of minutes, the turning point of the Pacific war.
Leyte Gulf, 1944. Generally regarded as the largest naval battle in history, fought from 23 to 26 October 1944 in the waters around the Philippines. Japan gambled almost its entire remaining fleet to stop the American landings and lost, and the Imperial Japanese Navy was broken as a fighting force.

How sea battles decided the fate of empires
Command of the sea has toppled empires as surely as any land campaign. From the oared triremes of Salamis to the aircraft carriers of Midway and Leyte Gulf, naval battles decided who could trade, invade and survive. The tools changed utterly across 2,400 years, but the prize, control of the water, never did.
