The Undead were originally used by the Necrolytes and Death Knights of the First and Second Wars, however that practice stopped after the death of Gul'dan and the abolishment of Necromancy by Thrall, the warchief of the New Horde.
The new generation of undead was created by the Lich King, Ner'zhul who had been transformed into a higher being by the demon lord Kil'jaeden. Once an Orcish shaman, Ner'zhul sought warlock powers and delved deeply into demonic magic, until he was confronted by Kil'jaeden, the dark lord of the Burning Legion. Ner'zhul bargained with the demons - in exchange for incredible power he would pledge the service of the enslaved Orcish horde to the demons, and open portals for the Horde to invade Azeroth. After his defeat by the Alliance his body was ripped to pieces and his spirit tortured, until Kil'jaeden decided to use him as the leader of a new invasion of Azeroth. As a check on his minion's tremendous new powers, Ner'zhul, now the "Lich King", was embedded in a great glacier in Northrend and watched over by vampiric dreadlords.
The Lich King was able to reanimate the body of any being that had fallen. After recruiting the Prince of Lordaeron, Arthas Menethil the second during the Reign of Chaos attacked Quel'thalas, the High Elven kingdom. The Elves fought against the Scourge, but the Scourge was triumphant and assimilated Sylvanas Windrunner and most of the High Elves into the undead.
The Lich King's power fluctuated, allowing Sylvanas Windrunner and the other reanimated High Elves (due to their strong bond to magic) to gain free will. Sylvanas Windrunner led her fallen brethren to the fallen city of Lordaeron and established a home, calling themselves "the Forsaken".
These dark warriors have founded a secret bastion underneath the ruins of Lordaeron's former capital city. Located deep beneath the cursed Tirisfal Glades, the labyrinthine Undercity is a sprawling citadel of evil. Within its shadowy confines, Sylvanas' royal apothecaries scramble to develop a devastating new plague - one which will not only eradicate their hated Scourge rivals, but the rest of humanity as well.
To further their dark aims, the Forsaken have entered into an alliance of convenience with the primitive, brutish races of the Horde. Holding no real loyalty for their newfound comrades, the Forsaken have duped them into fighting against their common enemy - the Lich King. Only time will tell how these disciples of doom will fare in their mission of vengeance.
