Which foreign powers supported Greek independence from the Ottoman Empire?

The struggle for Greek independence from the Ottoman Empire was significantly bolstered by the intervention of three major European powers: Great Britain, France, and Russia.12

While the Greek cause garnered widespread popular support in Britain and France, Russia’s involvement was driven by its traditional hostility toward the Ottoman Empire and a desire to support its Orthodox coreligionists in Greece. Faced with the potential defeat of the Greek rebels and reports of massacres against the population, these three nations intervened to secure an autonomous Greek state.21

The turning point occurred on October 20, 1827, at the Battle of Navarino, where the combined naval fleets of Britain, France, and Russia destroyed the Ottoman and Egyptian forces. This decisive victory crippled Ottoman naval power and eventually forced the sultan to recognize Greek independence in 1832. Following the conflict, these powers continued to protect the newly established independent monarchical state.12
