What is another word for letter of marque?
Pronunciation: [lˈɛtəɹ ɒv mˈɑːk] (IPA) 
A letter of marque, also known as a privateer's commission, is a document that allows a ship owner to become a legal pirate sanctioned by a government during wartime. Synonyms for a letter of marque include "letter of reprisal," "warrant," or "license." These synonyms denote the legal authority that ship owners and captains receive to engage in piracy for the purposes of capturing enemy ships, cargo, and goods. However, the use of these terms was more prevalent in earlier centuries, and today, such activities are considered illegal and condemned. Regardless of the term used, the underlying power of the document remains the same, allowing the receiver to engage in otherwise unlawful activities with a legal backing.
