    Letters of Marque covers much of this. mysticseaport has a more concise treatment. It appears that they probably were not issued after the war of 1812.

    The CSA issued letters of marque during the Civil War, and according to the Wikipedia article on Confederate privateers this is the last time they were used. Does the article I linked to answer your question?

1 Answer 1


The last time the United States Congress issued a letter of Marque and Reprisal was during the War of 1812. The last time they considered it was during Andrew Jackson's administration. The Declaration of Paris is an international law signed onto by over fifty nations. Created in 1856, the United States abides by the provisions thereto. It prohibits the act of privateering. Thus, although Congress have the Constitutional authority to grant letters of Marque, they essentially cannot do so without violating international law.
