The Odjak of Algiers (also spelled Ujaq or Ocak) was the local corps of the Janissary militia in the Regency of Algiers, forming the backbone of its professional army from around 1518 until the French conquest in 1830 (with de facto dissolution by 1837).
Highly autonomous within the broader Ottoman Janissary Corps, the Odjak operated independently from imperial headquarters in Istanbul, mirroring the Regency's own semi-independent relationship with the Sublime Porte. Recruited primarily from Anatolian Turks and other Ottoman subjects (often through voluntary enlistment or hereditary service within the corps), its members remained lifelong professional soldiers, largely insulated from local Algerian society.
Led by an Agha (commander-in-chief), the Odjak served multiple roles: as the Regency's main defensive force against external threats, a Praetorian Guard protecting (and sometimes deposing) rulers, and an instrument of internal repression and control until its power was curtailed in 1817.
The Odjak encompassed all Janissaries in Algiers as a dominant political faction. Its central institution was the Diwân of Algiers (divan or council), established in the 16th century by Hayreddin Barbarossa following the consolidation of Ottoman rule. Initially seated in the Djenina Palace (Palais de la Jenina), the assembly later moved to the Kasbah citadel (including the Palace of the Dey).
