Following the recapture of the Greek territories by the Ottoman Empire, the Great Powers of that time (the British Empire, the Russian Empire and the Kingdom of France) saw the Greek counter-offensive as an opportunity to weaken the Ottoman Empire further and in essence increase their influence in the Eastern Mediterranean. The Great Powers supported Greece to regain its independence and following a decisive battle in the Navarino Bay a cease fire was agreed in London (see Treaty of London (1827)). The autonomy of Greece was ultimately recognised by the London Protocol of 1828 and its full independence from the Ottoman Empire by the Protocol of London of 1830.
