Did the destruction of the Ottoman-Egyptian fleet at Navarino open the way for French colonization of Algiers?
Short answerIt made the operation easier, but the French Navy already possessed such a large advantage that the surviving Algerian forces were unlikely to stop it.
NotesThe Battle of Navarino removed naval strength that might have complicated French action, so it belongs in the causal background. The French Navy still vastly outweighed the forces available around Algiers. Navarino therefore eased the path to invasion without making the conquest possible by itself.
