The Romulans (/ˈrɒmjʊlənz, -jə-/) are an extraterrestrial race in the American science fiction franchise Star Trek. Their adopted home world is Romulus, and within the same star system they have settled a sister planet Remus. Their original home world, Vulcan, was renamed Ni'Var later in canon. They first appeared in the series Star Trek (1966–1969). They have appeared in most subsequent Star Trek releases, including The Animated Series, The Next Generation, Deep Space Nine, Voyager, Enterprise, Discovery, Picard, Strange New Worlds, and Lower Decks. They appear in the Star Trek feature films Star Trek V: The Final Frontier (1989), Star Trek VI: The Undiscovered Country (1991), Star Trek: Nemesis (2002) and Star Trek (2009). They also appear in various other spin-off media, including books, comics, toys and games.
Writer Paul Schneider created the Romulans for the 1966 Star Trek episode "Balance of Terror". As a basis, he considered what the ancient Roman Empire might have looked like had it developed to the point of spaceflight. Physically, the Romulans were presented as humanoid, but the show's make-up department gave them pointed ears to distinguish them from humans. In the series, which is set in the 23rd century, the Romulans were speculated as having split from another alien species, the Vulcans, in the distant past. In contrast to the Vulcans, who were presented as peaceful and logic-oriented philosopher scientists, the Romulans were depicted as militaristic, having founded an interstellar empire. The Romulans were used as antagonists for the series' protagonists, the starship USS Enterprise, her crew, and their government, the United Federation of Planets.
In 1987, the writers of Star Trek: The Next Generation—set in the 24th century—again used the Romulans as antagonists of the Federation. The show's designers gave the Romulans new costumes and added a V-shaped ridge on the foreheads of most Romulan characters, though with indications that Romulans without the ridges also existed. In the series Star Trek: Enterprise, Romulans without ridges are depicted as passing for Vulcans (who do not have ridges either). The 2009 film Star Trek depicted the Romulan homeworld, Romulus, being destroyed by a supernova in the year 2387. This film featured Romulans without the head ridges. The impact of Romulus's destruction forms a plot-theme in the series Star Trek: Picard. Romulans in that series have included those with and without ridges, and a line about northern Romulans may have been intended to refer to these two groups.
