Background
Commercial and educational networks, Orthodox communities, and Enlightenment-era national ideas supported independence projects. Filiki Eteria prepared revolt while the Ottoman Empire faced regional strains.
- Greek-speaking merchants and intellectuals built networks across the Ottoman world
- Enlightenment ideas and Orthodox memory supported visions of autonomy
- Great-power intervention turned a regional revolt into an international issue

Course
Uprisings spread through the Peloponnese and elsewhere in 1821, followed by the fall of Tripolitsa and civil war among Greek factions. Muhammad Ali's army intervened, but the naval battle of Navarino intensified great-power pressure.
- The Filiki Eteria prepared an uprising
- Revolt spread through the Peloponnese and the islands in 1821
- Naval warfare, sieges, and civil conflict tested the revolution

Outcome
The Treaty of Adrianople in 1829 and subsequent protocols moved the settlement toward Greek autonomy and independence. The 1830 protocol established international recognition, followed by kingdom-building.
- The Battle of Navarino made an Ottoman reconquest difficult
- Great-power diplomacy shifted the path from autonomy toward a state
- Greek independence received international recognition in 1830

Historical significance
Independence resulted from the interaction of a national movement, Ottoman administration, Egyptian military power, and Russian, British, and French strategy. War constrained the new state's borders and institutions.
- It linked national autonomy to great-power diplomacy
- Philhellenism moved public opinion across Europe
- It reshaped the political order of the eastern Mediterranean
