Harold Burned-Mane wrote: Black Marsh got that name when the outer swamps of Argonia were conquered by the Empire. Don't remember if it was the Second or the Third Empire. The term "Argonia" itself apparently comes from the Elven name of a very old battlefield in which the Elves fought the Argonias. As for the name "Black Marsh", that probably came from the Alessian Empire. Though it was the Reman Empire that first conquered portions of the province.
