The London Protocol of 1830 establishes the full independence and sovereignty of Greece from the Ottoman Empire as the final result of the Greek War of Independence.

The London Protocol of 1830, also known as the Protocol of Independence in Greek historiography, was a treaty signed between France, Russia, and Great Britain on 3 February 1830. It was the first official international diplomatic act that recognized Greece as a fully sovereign and independent state, separate from the Ottoman Empire. The protocol afforded Greece the political, administrative, and commercial rights of an independent state, and defined the northern border of Greece from the mouth of the Achelous or Aspropotamos river to the mouth of the Spercheios river. As a result of the Greek War of Independence, which had broken out in 1821, the autonomy of Greece in one form or another had been recognized already since 1826, and a provisional Greek government under Governor Ioannis Kapodistrias existed, but the conditions of the Greek autonomy, its political status, and the borders of the new Greek state, were being debated between the Great Powers, the Greeks, and the Ottoman government.

Greece, officially the Hellenic Republic, is a country in Southeast Europe. Located on the southern tip of the Balkan peninsula, it shares land borders with Albania to the northwest, North Macedonia and Bulgaria to the north, and Turkey to the east. The Aegean Sea lies to the east of the mainland, the Ionian Sea to the west, and the Sea of Crete and the Mediterranean Sea to the south. Greece has the longest coastline on the Mediterranean Basin, spanning thousands of islands and nine traditional geographic regions. It has a population of over 10 million. Athens is the nation's capital and largest city, followed by Thessaloniki and Patras.

The Ottoman Empire, also called the Turkish Empire, was an imperial realm that controlled much of Southeast Europe, West Asia, and North Africa from the 14th to early 20th centuries; it also controlled parts of southeastern Central Europe, between the early 16th and early 18th centuries.
