Black Uruks were the first Orc-kind of Middle-earth named uruk, originating centuries before the Great Years when they made assaults upon Ithilien in 2475 of the Third Age. (It was almost a millennium later that Saruman in Isengard bred the more familiar Orcs known as Uruk-hai.)
Within Mordor, an unknown number of Uruks were stationed at the Tower of Cirith Ungol. After escaping from there, the Hobbits Frodo and Sam saw Uruks march from Durthang towards the Black Gate amidst the mass-movement of all of Sauron's remaining forces.
Portrayal in adaptations
The Lord of the Rings film trilogy
In Peter Jackson's The Lord of the Rings: The Return of the King, Uruks of Mordor are frequently seen: the invented character Murgash is one of them, at the Siege of Gondor, and many others march through the Orc-camp encountered by Sam and Frodo in western Mordor. Most notably, Shagrat, in the Tower of Cirith Ungol, is portrayed as an Uruk.
All Black Uruks depicted in the films are recognizable by their broader stature and long hair resembling that of the Isengard Uruk-hai. Gorbag was therefore depicted as a Black Uruk, being instead skinny, with the natural slouch of other common Orcs.
Ambiguation in films and games
In some adaptations, the label of "Black Uruk" is sometimes made synonymous with Black Orc (such as in EA's The Rise of the Witch-king) or even Morannon Orc - on the grounds that all three names denote a tougher breed of Mordor-indigenous Orc.
