Alliance

The Alliance (a.k.a "The Grand Alliance") is one of the two major political factions of the mortal races in Azeroth, its counterpart being the Horde. The Alliance, was once also known as the Alliance of Lordaeron (or Alliance of humans, elves and dwarves) when its leadership was centered in Lordaeron. However, the Alliance was forced to move the bulk of its forces to Kalimdor and to the southern Azerothian kingdoms of Stormwind and Khaz Modan after a plague of undeath ravaged the Kingdom of Lordaeron several years ago. It has since lost many members, as well as gained new allies.
