According to the Alliance Player's Guide, while the kingdom was renamed sometime after the Third War to the current name of Kingdom of Stormwind, at the time of the First War it was known as the Kingdom of Azeroth.
The game featured two separate storylines, one concluding with victory for the orcs, the other with victory for the humans. For a discussion of which aspects of each storyline ultimately became part of the lore of the Warcraft universe, see the discussion of retcons.
In the Age of Chaos, two factions battled for dominance. The Kingdom of Azeroth was a prosperous one. The Humans who dwelled there turned the land into a paradise. The Knights of Stormwind, and the Clerics of Northshire Abbey, roamed far and wide serving the king's people with honor and justice. The well-trained armies of the King maintained a lasting peace for many generations. Then came the Orcish Hordes.
No one knew where these creatures came from, and none were prepared for the terror that they spawned. Their warriors wielded axe and spear with deadly proficiency, while others rode Darkwolves as black as the moonless night. Unimagined were the destructive powers of their evil magic, derived from the fires of the underworld.
With an ingenious arsenal of weaponry and powerful magic, these two forces collide in a contest of cunning, intellect, and brute strength, with the victor claiming dominance over the whole of Azeroth. Welcome to the world of Warcraft.
Orc CampaignBlackhand has assigned you to an outpost in the Swamps of Sorrow. Your task is simple enough that even the War Chief feels you are capable of it. Construct at least six farms, so that we may keep our troops well fed and ready to do battle.

Victory for the Horde
With the decimation of the Human forces, the sacking of their castle was a simple matter. They offered little resistance once you ran their weak leader through with your war blade and toppled his body into the moat.

No peasants dare approach the vile temple, and only the bravest of your soldiers have agreed to accompany you on this mission. You must strike boldly and without err, for there will be no reinforcements. Rockard and Stonard are all that stand between the forces of the kingdom and Blackhand's stronghold - Black Rock Spire.

Victory for Azeroth
