Strategic Narrative Overview
The invasion launched on 14 June 1830 with a naval bombardment under Admiral Duperré and a land assault led by Bourmont. French forces rapidly defeated the regular troops of Hussein Dey. However, widespread native resistance from figures including Ahmed Bey, Emir Abdelkader, and Lalla Fatma N'Soumer turned the campaign into a protracted counterinsurgency lasting more than 45 years across the territory.
01 / The Origins
A diplomatic dispute in 1827, the 'Fan Affair', gave France a pretext to blockade the port of Algiers. After three years of stalemate, a further provocation—a French ship carrying an ambassador being fired upon—pushed Charles X toward military intervention. The king also sought to distract from severe domestic unrest in France, which would soon culminate in the July Revolution and his own deposition.
03 / The Outcome
The Regency of Algiers was dissolved and French colonial rule established. Charles X was deposed during the July Revolution before the campaign concluded. By 1848, the conquered territories were reorganised into three French départements, forming the administrative basis of modern Algeria and entrenching a colonial structure that endured until Algerian independence in 1962.
