Algeria Colonized by France

In 1830, France landed an army on the coast of Ottoman Algeria and captured the city of Algiers, beginning a conquest that would last well over a decade and a colonial presence that endured for 132 years. The invasion launched France's North African empire and shaped the politics, demography, and memory of both countries long after Algeria won independence in 1962.

Algeria in the early nineteenth century was a semi-autonomous province of the Ottoman Empire, governed from Algiers by a ruler known as the dey. Its relationship with France was strained by commercial disputes, including debts tied to French grain purchases during the Napoleonic era. A well-known diplomatic quarrel in 1827 between the dey and the French consul is traditionally cited as the spark, though historians generally see it as a pretext. The restored Bourbon monarchy of Charles X was unpopular at home and hoped a military success abroad would boost its prestige. Naval pressure and a blockade of Algiers preceded the invasion.

The French expeditionary force landed west of Algiers in June 1830 and took the city in early July after a brief campaign, and the dey agreed to surrender and go into exile. The victory did not save the regime: Charles X was overthrown in the July Revolution just weeks later. The new government under Louis-Philippe chose not to withdraw, and French control gradually expanded from the coastal towns. The occupation was initially limited and uncertain, with no clear plan for what France intended to do with its new possession.

The conquest of the interior proved long and brutal. Resistance was led most prominently by Abd al-Qadir, who built a state in western and central Algeria and fought the French through the 1830s and 1840s until his surrender in 1847. French commanders, notably Thomas Robert Bugeaud, used scorched-earth tactics, destroying crops and villages and forcing displacement. Algerian deaths from war, famine, and disease were severe, though historians differ on the precise toll. Later uprisings, such as the Kabyle revolt of 1871, were also put down harshly.

Algeria was eventually treated not as a colony but as an integral part of France, divided into departments. Large amounts of land were taken for European settlers, who became known as colons, while most Muslim Algerians were denied equal citizenship and political rights. These inequalities fueled nationalism and, from 1954, the Algerian War of Independence. The legacy of the conquest remains contested, and debates over colonial memory, apology, and historical responsibility continue in both France and Algeria.
