Ottoman Algeria

“The Mediterranean curled around Algiers like a second wall.”

Ottoman Algeria was a powerful regency centered in Algiers. From the 16th century to 1830, it played an important role in Mediterranean politics, trade, and warfare. Local rulers, military elites, and Ottoman influence shaped the region long before French colonization began.

Curator's note

The Ottoman period made Algiers a self-governing Mediterranean power with its own navy, diplomacy and identity. Far from a distant province, it was a state learning to act on its own terms.
