9 Reasons Return Of The Jedi Wasn't The End Of The Empire

[هَـ-ђāŵĩ-ـَاوِي]

Although the Battle of Endor in Return of the Jedi saw the defeat of the Emperor and the destruction of the second Death Star, it was absolutely not the end of the Empire in the Star Wars timeline. Lasting for 24 years by the time of the Emperor's first death, the reign of the Empire is probably the central story of this universe. Characters are defined and changed by either fighting for or against, or even around, the Empire.
