Barangil

Black Men or Barangils is a common term in Gondor to describe the dark-skinned peoples of southern Middle-Earth, especially those of Far-Harad and the Utter South.While some Scholars see the black men as Haradrim and call the "southern Haradrim", "Black Haradrim" or "Far-Haradrim", others consider them a culture of their own, separate from those tribes of (known) Haradwaith.

Other Westron speaking peoples -as the Hobbits - also call them by the pejorative term "Swertings".

The Black men in MERP
The Black men are believed to be descendants of the Aravador.One aravadorian group, the Narnerim were a number of different tribes that entered the Southlands in the first age, after escaping the Battle of Palisor.Of those were the Haruze, or northern Haradrim, the Apysani or southern Haradrim and the Moredain or Moratani, a number of tribes that entered the savannahs and dark forests of the south.The latter became the ancestors of the Mûmakani, Kirani and Sharaeki, but especially in the Far-Harad, the Apysani and Black Men intermingled and produced many mixed peoples and tribes.Among these the Adena, Sederi and Tantûraki are deeply influenced by Númenórean Culture, for their realms emerged from former Colonies of the Men of Westernesse, other cultures as the Kirani had befriended Avari of the utter south and developed into a culture of elf-friends.Others came under the shadow, such as the men of Mûmakan who were seduced by the Nazgûl Indûr Dawndeath, many other peoples and tribes however hid in the deep forests and mountains and remain in their own ancient ways.

Black peoples outside Harad
The Ts´dan, K´prur and Jôpi are also of Narnerim descent and close relatives of the Moredain of the southlands, probably descendants of groups who left the Narnerim during their great migration.

Speculations
The Mahûd of the movie Trilogy seem to be based on the Black men who took part in the Battle of the Pelennor Fields.
