The political faction that Sigmar Heldenhammer is the patron deity of is based on what real-world empire?
The Empire (Warhammer) In Games Workshop's "Warhammer Fantasy" fictional universe, The Empire is one of the human political factions and armies, and is featured in many games and novels. In terms of location, language, culture, and society, it is clearly based on the real-world medieval Holy Roman Empire.
Galactic Republic The Galactic Republic, often referred to as simply the Republic, is the name of the interplanetary State used in the fictional "Star Wars" universe prior to the establishment of the Galactic Empire. The form of this government, ruled by the Senate, was introduced in the prequel trilogy. By the time of the original trilogy, it is referred to as the Old Republic. It was a democratic, though eventually ineffectual, constitutional republic tied up in layers of bureaucracy.
