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.
