Greece’s independence is recognized by the Treaty of London.

The independence of Greece was formally recognized through the Treaty of London, signed on July 6, 1827, by Great Britain, France, and Russia. This treaty marked a pivotal moment in the Greek War of Independence (1821–1829), during which the Greeks revolted against Ottoman rule. Although initially these powers aimed to establish Greek autonomy under Ottoman suzerainty, the situation evolved following the Battle of Navarino later that year, where the allied fleet decisively defeated the Ottoman-Egyptian navy. This shift in military balance increased diplomatic pressure on the Ottoman Empire. Ultimately, Greek independence was fully acknowledged by the Treaty of Constantinople in 1832, but the 1827 Treaty of London laid the diplomatic groundwork by legitimizing European intervention and signaling international support for the Greek cause.
