In this final episode of our series on the Barbary Wars, we look at the fates of the Barbary States. After 1815, the Barbary States lost their independence, with Algiers, Tunis, Tripoli, and Morocco succumbing to European powers through military defeats and colonization, culminating in French and Spanish protectorates by the 19th century. We also look at how the Barbary Wars placed the United States on a pathway to global naval hegemony.
