As far as I'm aware, Black March was only ever conquered once, during the novels The Infernal City and Lord of Souls. The evil guy (I can't remember his name) basically just slaughtered the Argonians, got the Hist to betray them (I think), and then raised them as undead. That guy was a bit of a crazy mofo, and he basically conquered Black Marsh. He didn't exactly fight fair though, so I don't know if he counts.
