Horde

From wow.incgamers.com

The Horde is the commonly used name for the alliance of "outcast" races on Azeroth. Mainly populated by the Orcs, and formerly also known as the "Orcish Horde", their current leader Warchief Thrall have also let in Darkspear Trolls, the Tauren clans, the Forsaken who have escaped Scourge control, and the Blood Elves, formerly known as High Elves.

To a great extent the Horde only wants to be kept at their own accord, and not to bother anyone, but if there is conflict afoot, they are the first to heed the call of battle.
