Seven Kingdoms

The Seven Kingdoms were the human city-states founded after the Troll Wars and the fracturing of the great empire of Arathor, approximately 1,200 years before the First War. Though most held a sphere of influence including only their original cities, some, notably Lordaeron and Azeroth/Stormwind, came to control vast territories in the Eastern Kingdoms.

Current status
At the time of World of Warcraft, Alterac and Lordaeron have fallen, Stromgarde is hard pressed keeping what small territory they haven't lost yet, while Dalaran has relocated to Northrend to battle the Scourge, after recovering from attacks by the Scourge and the Burning Legion during the Third War. Stormwind was flourishing until a surprise attack on its capital by Deathwing, Gilneas has been ravaged by the Worgen curse and a Horde invasion, while the state of Kul Tiras is (still) unknown. The only major human settlement in Kalimdor is Theramore Isle, founded by Lady Jaina Proudmoore following the Third War.

World of Warcraft: Cataclysm
After the Cataclysm, Gilneas was brought back into the Alliance's fold, though still under the Worgen curse.

Prince Galen Trollbane of Stromgarde has been raised as a Forsaken.
