Greek War of Independence: The London Protocol entails the creation of an autonomous Greek state under Ottoman suzerainty, encompassing the Morea and the Cyclades.

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.

The London Protocol of 16 November 1828 was an agreement among the three Great Powers, which established the creation of an internally autonomous, but tributary Greek state under Ottoman suzerainty.

Morea was the name of the Peloponnese peninsula in southern Greece during the Middle Ages and the early modern period. The name was used by the Principality of Achaea, the Byzantine province known as the Despotate of the Morea, by the Ottoman Empire for the Morea Eyalet, and later by the Republic of Venice for the short-lived Kingdom of the Morea.

The Cyclades are an island group in the Aegean Sea, southeast of mainland Greece and a former administrative prefecture of Greece. They are one of the island groups which constitute the Aegean archipelago. The name refers to the archipelago forming a circle around the sacred island of Delos. The largest island of the Cyclades is Naxos; the most populated, however, is Syros.
