Photograph of Hangar Burning after Japanese Air Raid on Pearl Harbor

The first recorded sea battle occurred about 1210 BC: Hittites defeated and burned the Cyprus fleet. Athens protected itself from Persia by building a fleet paid for by silver mines profits. Romans developed the technique of grappling and boarding enemy ships with soldiers. Constantinople invented a Greek fire, a flamethrower to burn enemy's ships. Torpedo was invented by the Arab Hasan al-Rammah in 1275. With the Age of Discovery, naval actions in defense of the new colonies grew in scale. In 1588, Spain sent Armada to subdue the English fleet of Elizabeth, but Admiral Sir Charles Howard won the battle, marking the rise of the Pax Britannica. Anglo-Dutch Wars were the first wars to be conducted entirely at sea. Most memorable of these battles was the raid on the Medway, in which the Dutch sailed up the river Thames, and destroyed most of the British fleet. The 18th century was a period of continuous naval wars, in the Mediterranean, in the Atlantic Ocean, and in the Baltic Sea. The Napoleonic Wars culminating in the Battle of Trafalgar in 1805. With the advent of the steamship, it became possible to create massive gun platforms and to provide them with heavy armor protection. The battle of the CSS Virginia and USS Monitor in the American Civil War that symbolized the changing times. In the 20th century, the steel-armored battleships with large shell turret guns emerged. The Russo-Japanese Battle of Tsushima in 1905 was the first test of the new concepts, resulting in Japanese victory. Airpower became key to navies throughout the 20th century, moving to jets launched from ever-larger carriers, and augmented by cruisers armed with guided missiles and cruise missiles. During the Pacific War of World War II, the carriers and their airplanes were the stars and the United States became the world's dominant sea power. The Falklands War, however, showed the vulnerability of modern ships to sea-skimming missiles. Parallel to the development of naval aviation was the development of submarines. In the 1950s the Cold War inspired the development of ballistic missile submarines.

This is an attempt to see World War 2 through the eyes of people who lived or fought on the territories controlled by the Axis powers, originally the Rome–Berlin Axis. Axis' principal members in Europe were Nazi Germany, the Kingdom of Italy, Hungary, and Spain. During World War II, Nazi Germany and Axis powers occupied or controlled a number of countries in Europe and beyond. At its zenith in 1942, the Axis presided over large parts of Europe, North Africa, and East Asia, either through occupation, annexation, or puppet states.
