Which 2005 film was the final installment of the Star Wars prequel trilogy?

The final installment of the Star Wars prequel trilogy was Revenge of the Sith, released in 2005. Its full title is Star Wars: Episode III – Revenge of the Sith, and it bridges the story of the first two prequels with the original trilogy that began in 1977.

The film follows Anakin Skywalker during the Clone Wars as Chancellor Palpatine manipulates him with promises of power and a possible way to prevent Padmé Amidala’s death. Anakin eventually falls to the dark side, becomes Darth Vader, and helps Palpatine establish the Galactic Empire. The film also depicts the destruction of the Jedi Order, including the execution of Order 66 across the galaxy.

Chronologically, Revenge of the Sith comes after The Phantom Menace and Attack of the Clones. Its title refers to the Sith’s return to dominance and the revenge they take against the Jedi, not to the later sequel-trilogy film The Force Awakens. Although it was the third prequel released, it is numbered Episode III because the prequels were designed to reveal the events leading directly into the original Star Wars film, later retitled Episode IV – A New Hope.
