Who supported the Barbary pirates and went to war with the us?

The Barbary pirates were primarily supported by the North African states of Algiers, Tunis, and Tripoli, which engaged in piracy against American and European shipping in the Mediterranean Sea. The United States went to war with these states, notably during the First Barbary War (1801-1805) and the Second Barbary War (1815), in response to the demands for tribute and the capture of American merchant ships. The conflicts aimed to protect American interests and assert naval power in the region.
