History
Main article: Protoss history

The Empire was formed out of the ashes of the Aeon of Strife, the mystic Khas developing a caste system through which protoss society would function. The Judicator Caste would be composed of leaders and statesman, the Templar Caste of warriors and the Khalai Caste of artisans, scientists and builders. Those who refused to conform were banished from Aiur, becoming known as the Dark Templar.

The Empire came to be composed of hundreds of worlds. Under the dictates of the Dae'Uhl, the Empire had a policy of non-interferance towards "lesser races," who were unaware of the protoss' existance. When conflict with other species did break out, such as the Kalathi Intercession, protoss technology stood triumphant. Their successes led the protoss to consider themselves to be the most powerful species in the galaxy, even the newly arrived terran powers in the Koprulu Sector being a shadow of their might.

The Empire met its end in the Great War, with the Zerg Swarm invading its capital world of Aiur. Although the protoss stood triumphant at the eleventh hour, it was a hollow victory. With the zerg running rampant across their world and their millitary might decimated, the protoss were effectively made refugees, fleeing to Shakuras for refuge amongst the Dark Templar. By 2502, this conglomeration of Khalai and Nerazim had been re-organized into the Protoss Protectorate.
