ordered the assassination of Selim, and seized the town and ousted the Spanish in the Capture of Algiers (1516). Hayreddin, succeeding Oruc after the latter was killed in battle against the Spaniards in the Fall of Tlemcen (1517), was the founder of the pashaluk, which subsequently became the beylik, of Algeria. Barbarossa lost Algiers in 1524 but regained it with Capture of Algiers (1529), and then formally invited the Sultan Suleiman the Magnificent to accept sovereignty over the territory and to annex Algiers to the Ottoman Empire.

Algiers from this time became the chief seat of the Barbary pirates. In October 1541 in the Algiers expedition, the King of Spain and Holy Roman Emperor Charles V sought to capture the city, but a storm destroyed a great number of his ships, and his army of some 30,000, chiefly made up of Spaniards, was defeated by the Algerians under their Pasha, Hassan.

Formally part of the Ottoman Empire but essentially free from Ottoman control, starting in the 17th century Algiers turned to piracy and ransoming. Due to its location on the periphery of both the Ottoman and European economic spheres, and depending for its existence on a Mediterranean that was increasingly controlled by European shipping, backed by European navies, piracy became the primary economic activity. Repeated attempts were made by various nations to subdue the pirates that disturbed shipping in the western Mediterranean and engaged in slave raids as far north as Iceland.The United States fought two wars (the First and Second Barbary Wars) over Algiers' attacks on shipping.
