The Imperial March was composed by John Williams for the 1980 film Star Wars: The Empire Strikes Back. Also known as Darth Vader’s Theme, it became a recurring musical symbol for Vader and the Galactic Empire across the franchise. Short excerpts later spread through online videos, edits, reaction posts, and soundboards because the melody communicates villainy almost instantly. It remains popular for dramatic entrances, mock displays of authority, and Star Wars jokes, often alongside other franchise audio associated with characters such as Chewbacca.
