Darth

Darth is a title used by Sith Lords in the Star Wars universe. It functions as a formal designation that accompanies the bearer’s name and signals allegiance to the dark side of the Force. The title is typically bestowed by a Sith master to an apprentice, who then adopts Darth as a prefix to a chosen name. In this way, the title marks the lineage and the power dynamic within the Sith order, and it is often displayed in contrast to the Jedi's use of given names.

The origin of the term within the Star Wars fiction is not precisely defined, but it is widely interpreted as derived from "dark" or "dark lord," and it has been used since the early films and expanded works to designate Sith Lords. The practice matured with the Rule of Two, a doctrine in which a master and an apprentice survive to concentrate power in the Sith order.

Notable Sith who bore the title include Darth Vader, Darth Sidious, Darth Maul, and Darth Tyranus. In the broader Star Wars expanded universe, figures such as Darth Bane and Darth Revan appear in Legends continuity, and references to Darth Plagueis exist in canon materials. The term remains a recognizable symbol of Sith identity across films, novels, comics, and games, underscoring themes of power, secrecy, and corruption.
