Greek War of Independence: Konstantinos Kanaris leads a Greek fleet to victory against Ottoman and Egyptian naval forces in the Battle of Samos.

The Greek War of Independence, also known as the Greek Revolution or the Greek Revolution of 1821, was a successful war of independence by Greek revolutionaries against the Ottoman Empire between 1821 and 1829. In 1826, the Greeks were assisted by the British Empire, Kingdom of France, and the Russian Empire, while the Ottomans were aided by their vassals, especially by the Eyalet of Egypt. The war led to the formation of modern Greece, which would be expanded to its modern size in later years. The revolution is celebrated by Greeks around the world as independence day on 25 March.

Konstantinos Kanaris, also anglicised as Constantine Kanaris or Canaris, was a Greek statesman, admiral, and a hero of the Greek War of Independence.

The Battle of Samos was a naval battle fought on August 5–17, 1824 off the Greek island of Samos during the Greek War of Independence.
