He was born and grew up on the island of Psara, close to the island of Chios, in the Aegean. His exact year of birth is unknown. The official records of the Hellenic Navy indicate 1795 but modern Greek historians believe that 1790 or 1793 is more probable. Constantine was left an orphan at a young age. Having to support himself, he chose to become a seaman like most members of his family since the beginning of the 18th century. He was hired as a boy on the brig of his uncle Dimitris Bourekas.
Military career
Constantine gained his fame during the Greek War of Independence. Unlike most other prominent figures of the War, he had never been initiated into the Filiki Eteria, which played a significant role in the revolution against the Ottoman Empire, primarily by secret recruitment of supporters against the Empire. By early 1821, it had gained enough support to declare a revolution. This declaration seems to have surprised Constantine, who was absent at Odessa. He returned to Psara in haste and was there when the island joined the Revolution on 10 April 1821. The island formed its own fleet of ships and the famed seamen of Psara, already known for their successful naval combats against pirates and their well-equipped ships, proved to be effective at full naval war. Constantine soon distinguished himself as a fire ship captain. by Kanaris. At Chios, on the moonless night of 6–7 June 1822 forces under his command destroyed the flagship of the Turkish admiral Nasuhzade Ali Pasha in revenge for the Chios massacre. The admiral was holding a celebration, so Kanaris and his men managed to place a fire ship next to it without being noticed. When the flagship's powder store caught fire, all men aboard were instantly killed. The Ottoman casualties comprised 2300 men, both naval officers and common sailors, as well as Kara-Ali himself. Later in the year he led another successful attacks against the Turkish fleet at Tenedos in November 1822. The Turkish fleet captured Psara on 21 June 1824. A part of the population, including Kanaris, managed to flee the island, but those who didn't were either sold into slavery or slaughtered. After the destruction of his home island, Kanaris continued to lead his men into attacks against the Turks. He took part to sea fights in the Dodecanese in August 1824. In August 1825, Kanaris led the raid on Alexandria, a daring attempt to destroy the Egyptian fleet via fire ships that might have been successful if the wind had not failed just after the Greek ships entered Alexandria harbor. Following the end of the war and the independence of Greece, Constantine became an officer of the new Greek Navy, reaching the rank of admiral, and later became a prominent politician.
Political career
Constantine Kanaris was one of the few with the personal confidence of Ioannis Kapodistrias the first Head of State of independent Greece. Kanaris served as Minister in various governments and then as Prime Minister, in the provisional government, from 11 March to 11 April 1844. He served a second term, and as Navy Minister in Mavrokordatos' 1854 cabinet. In 1862, he was one of the few War of Independence veterans that helped in the bloodless revolution that deposed King Otto of Greece and put Prince William of Denmark on the Greek throne as King George I of Greece. Under George I, he served as a prime minister for a third term, fourth term and fifth and last term. Kanaris died on 2 September 1877 whilst still serving in office as Prime Minister. Following his death his government remained in power until 14 September 1877 without agreeing on a replacement at its head. He was buried in the First Cemetery of Athens, where most Greek prime ministers and celebrated figures are also buried. After his death he was honored as a national hero. To honour Kanaris, three ships of the Hellenic Navy have been named after him;
Wilhelm Canaris, a German Admiral, speculated that he might be a descendant of Constantine Kanaris. An official genealogical family history that was researched in 1938 showed that he was unrelated and that his family was from Italy.
