The Royal Hellenic Navy was the fleet of the Kingdom of Greece, with its origins in the Greek War of Independence against the Ottoman Empire. It carried the name Royal Navy during the periods of monarchy in Greece (1833–1924 and 1936–1973). Due to the maritime nature of Greece, the navy was always considered important for the country's security.
It was notable for its role in both the war of independence from the Ottomans, where it used small-ship tactics to harass the larger Turkish warships, and the Greek Liberation of Crete, in which it landed troops on the island of Crete and kept them supplied against Ottoman Egypt's attempts to cut them off. Eventually the Egyptians were forced to capitulate to Greek demands regarding Crete as the Royal Navy successfully kept the occupying Army of Epirus supplied, making it part of Greece.
