The Second Barbary War (1815), also known as the Algerine or Algerian War, was the second of two wars fought between the United States and the Ottoman Empire's North African regencies of Tripoli, Tunis, and Algeria, known collectively as the Barbary states. The war between the Barbary states and the U.S. ended in 1815; the international dispute would effectively be ended the following year by Great Britain and the Netherlands.
