The First Galactic Empire is a fictional autocracy featured in the Star Wars franchise. It was first introduced in the 1977 film Star Wars and also appears in its two sequels: The Empire Strikes Back (1980) and Return of the Jedi (1983) and is the main antagonist faction of the original trilogy.
The Imperial crest was the six-spoked symbol of Sheev Palpatine's Galactic Empire. It adorned many things Imperial, from uniforms and starships to flags and propaganda posters. It was a modified version of the eight-spoked roundel that the Galactic Republic used as their crest during the Clone Wars.
The Imperial insignia was designed by John Mollo, who was the costume designer for Star Wars: Episode IV A New Hope and Star Wars: Episode V The Empire Strikes Back. In the Q&A feature of the 98th issue of Star Wars Insider magazine, Mollo revealed that he based the Imperial insignia on shapes used in 18th century fortifications.
