The Blackbirder

To those millions of people stolen from Africa and upon whose long-forgotten backs this country was raised to greatness

Pirate-a sea-robber, or an armed ship that roams the seas without any legal commission, and seizes or plunders every vessel she meets indiscriminately, whether friends or enemies.

Privateer-a vessel of war, armed and equipped by particular merchants, and furnished with a military commission by the admiralty, or the officers who superintend the marine department of a country, to cruise against the enemy and take, sink, or burn their shipping, or otherwise annoy them as opportunity offers. These vessels are generally governed on the same plan with his majesty’s ships, though they are guilty of many scandalous depredations, which are very rarely practiced by the latter.

– William Falconer
