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 3 February 1830 stands as a landmark agreement in European diplomatic history, formally recognizing Greece as an independent and sovereign state. This pivotal accord was meticulously crafted between the three dominant European powers of the era: The United Kingdom of Great Britain and Ireland, The Kingdom of France, and the Russian Empire. It served to amend and supersede the preliminary decisions outlined in the 1829 London Protocol, marking a decisive shift in the geopolitical landscape of the Eastern Mediterranean.

The Road to Independence: From Uprising to International Recognition

The genesis of independent Greece lay in the protracted and arduous Greek War of Independence, which erupted in 1821 against the long-standing rule of the Ottoman Empire. This struggle for national liberation garnered significant European sympathy, leading to the eventual intervention of the Great Powers. A crucial turning point arrived with the Battle of Navarino in October 1827, where the combined naval forces of Britain, France, and Russia decisively crushed the Ottoman-Egyptian fleet. While somewhat accidental in its scale, this engagement irrevocably altered the balance of power and made the establishment of some form of Greek state in southern Greece an inevitable outcome.

Amidst this unfolding crisis, the Greek Third National Assembly, convened in Troezen in 1827, entrusted the governance of the nascent nation to Ioannis Kapodistrias. A seasoned statesman with a distinguished career, including service as Russia's Foreign Minister, Kapodistrias arrived in Greece in January 1828. His immediate priorities were twofold: to lay the administrative and institutional foundations for a modern, functional state from the remnants of a war-torn society, and concurrently, to engage in complex negotiations with the Great Powers regarding the geographical extent and constitutional status of the newly emerging Greek state.

The Evolution of Greek Sovereignty: 1829 vs. 1830 Protocols

The diplomatic discussions culminated in the signing of the first London Protocol in March 1829 by the foreign ministers of the Great Powers. This initial agreement envisioned Greece as an autonomous, tributary state, nominally under Ottoman suzerainty. It stipulated that Greece would be governed by an elected Christian prince and its territory would encompass the historical heartlands of the Greek uprising: the Peloponnese (Morea), Continental Greece, and the Cycladic islands. However, this arrangement fell short of the full independence for which the Greeks had fought so dearly.

Kapodistrias, leveraging his profound diplomatic acumen and aided by the significant Russian victory in the Russo-Turkish War of 1828–29 (which concluded with the Treaty of Adrianople in September 1829 and pressured the Ottomans), persistently advocated for complete independence. These relentless efforts led to a crucial revision of the protocol, resulting in the groundbreaking London Protocol of 3 February 1830. This amended agreement fundamentally altered Greece's status:

The Final Settlement: The London Conference of 1832

The question of the Greek monarchy and final territorial delineation was subsequently addressed in the London Conference of 1832. This conference further amended the earlier protocols, definitively establishing the final borders of the newly formed Kingdom of Greece. It also resolved the succession crisis by offering the crown to the Bavarian prince Otto Friedrich Ludwig von Wittelsbach, who accepted and ascended the throne as Otto I of Greece, thereby ushering in the Bavarian regency and laying the groundwork for the modern Greek state.
