The Horde

"I see now why your Alliance and your Horde cannot stop fighting. Every reprisal is itself an act of aggression, and every act of aggression triggers immediate reprisal."

- Taran Zhu

In World of Warcraft there is no good and evil side when it comes to the ongoing conflict between the Alliance and the Horde, they both think of each other as evil and their side as good (due to Demonization and acts of aggression by rogue members of both factions). Both factions are either at war with each other, engaged in a cold war against eachother, or under an uneasy peace treaty that can be broken at anytime.

The Alliance think of the Horde as brutal barbarians who would ravage and destroy their lands due to the acts of corrupt Orcs and Undead - (in the original Warcraft mythos Orcs and Humans were bitter enemies and despite new leadership they still distrust one another due to prejudice and injustice on both sides).

The Horde think the Alliance are arrogant tyrants who consider themselves superior and the the Horde are sub creatures, the Horde worry that the Alliance would hunt them down and destroy them.

The truth is they're both right, certain members from the Alliance and Horde races have wronged each other and because of that there has been mistrust between them, blaming all for the actions of a few. The problem between them is racism.

The only things that can bring peace between these two factions are mutual enemies such as the Burning Legion.

Horde as villains

 * 1) Hellscream was a tyrant who tried to rule Azeroth, he was a tyrant amongst the Horde and he kidnapped Pandaren cubs to force neutral Pandaren to join the Horde.  In the end, both the Alliance and the Horde work together to defeat him.
 * 2) Demon-corrupted Orcs destroyed many Human cities.
 * 3) Orcs killed many Draenei during their bloodlust.
 * 4) The Forsaken invaded Gilneas.
 * 5) Many Goblins are known to be greedy when it comes to money; many would do any thing when come to wealth no matter how wicked.
 * 6) Some Blood Elves worked to destroy the Draenei.
 * 7) Hellscream had the Sunreavers steal the Divine Bell, and because Jaina was still traumatized by the destruction of Theramore, completely destroyed Jainna's hope for peace and made her hate the Horde and caused her to purge Dalaran of the Horde influence.

Working Together
Despite their hostilities, both sides have worked together amongst greater threats, such as The Burning Legion, The Lich King, Deathwing, and Garrosh Hellscream. Both sides have also shown signs of respect for one another and both sides have made attempts to peace. By Warlords of Draenor, the Alliance and Horde still have some tension but by now it's mostly a cold war status. However, aside from skirmishes (PVP), both sides are working together to bring down the Iron Horde.

Horde's respect for the Alliance

 * 1) Baine and Anduin became friends and thus the Tauren protected the young prince.
 * 2) Some members of the Horde were disgusted by the destrucion of Theramore.
 * 3) Thrall has limited respect for the Alliance, even if his past means he can't trust them fully - he is at least willing to try and co-exist with them and doesn't hate them fully. (which is more than can be said for Garrosh or other radicals in the Horde).
 * 4) During Patch 5.3 Escalation, Vol'jin accepted help from the Alliance to obtain supplies from the Kor'kron.
 * 5) The Horde tried to assist the Alliance during the Wrathgate attack.
 * 6) The Darkspear Trolls went to Stormwind to warn the Alliance about the plans of the Zandalari.
 * 7) During Garrosh's reign, the Blood Elves considered rejoining the Alliance.  When Jaina kicked the Sunreavers out of Dalaran, the Blood Elves held Garrosh just as responsible for their exile as much as they held Jaina responsible.
