Odjak of Algiers Revolution

The Revolution of the Odjak, also known as the Aghas Revolution or the Revolution of 1659 was an important military revolution that changed the essential bases of the government of the Ottoman Regency of Algiers, as well as its relations with the imperial centre in Istanbul. Taking place during a period of transformation of the Ottoman Empire, and lasting from June to September 1659, it was largely viewed as a result of the loss of the importance that the Regency previously had for Constantinople back in the 16th century; decades of marginalization demonstrated through the appointment of incompetent governors and diverging interests regarding relations with European powers, made both the Barbary corsairs and the janissaries of Algiers less inclined to commit themselves to the Ottoman cause.
