The Romulan Star Empire, also known in some Romulan languages as the Rihannsu Star Empire is the primary Romulan state. Located in the Beta Quadrant, the Romulan Star Empire was founded through the unification and conquest of the planet Romulus and of dozens of star systems over many sectors of space. The Romulan Star Empire is known to have existed as long ago as 2152, when it made first contact with United Earth, and is infamous for its ethnocentric, xenophobic, and expansionist foreign policy.
The Romulan Star Empire formed after a group of Vulcans left the Vulcan home world and resettled on Romulus in the 3rd century. In the 22nd century the Empire made attempts to destabilize local space eventually leading to the Earty-Romulan war. The Romulans saw defeat in the war and retreated behind the newly established Romulan Neutral Zone for the next century.The Romulans re-emerged in the mid-23rd century, had several minor aggressive encounters with the Federation and entered a short lived alliance with the Klingon Empire before retreated back behind their borders early in the 24th century following the Tomed Incident.The Empire re-emerged once more in the mid-24th century following attacks by the Borg and later participated in the Dominion War.
The emblem of the Romulan Star Empire is known as "the Eagle". It is a symbol of military might and honor, displayed on the bridge of every Romulan warship, yet also symbolizes civilian pride in the Romulan state, and is found at public facilities throughout the Empire. Romulan officers, and sometimes civilians, swear oaths upon the Eagle, and defacing the symbol is a serious offense. The original inspiration for the design came when the family emblem of S'Task was crossed with an artistic representation of an avian life-form native to Romulus. The first scout parties to chart the Rihannsu's new home world encountered huge eagles carrying their eggs in their talons; today the Eagle grasps Romulus and Remus in its claws.
The former is gripped protectively, indeed as a mother cradles an egg, the latter, held in thinner, sharper claws, and appears instead as a prey item. The bird itself is spread in an aggressive posture of display, representing the glory and majesty of the Star Empire. Its head is positioned with the beak pointing down, mirroring the triangle on which it is mounted. This triangle recalls the Vulcan Kol-ut-shan,the symbol of Surak's philosophies,which were without end, but began at a single point, Mount Seleya.
The Romulans have used the same design, representative of the (one sided) noble hatred and honorable feud between S'Task's followers and Surak's. On the Romulan banner, however, the point of beginning is missing, as the triangle's point is detached from any anchoring symbol. This, of course, is because Mount Seleya has been left far behind. Vulcan philosophies, here taken to mean the passionate warrior culture Surak destroyed, are still presented as being without end, widening out and leading the entire galaxy into the glory of the Romulan Empire, whose perfect strength and honor is announced by the slogan always displayed at the inverted triangle's top. It should also be noted that the triangle resembles a dagger, especially as it is colored in a dull metallic silver. The fact that the Eagle's beak mirrors the triangle, pointing with the dagger and looking back towards the sundered beginning, serves to make the symbol an aggressive attack on Surak's Vulcan, which, while clearly out of sight, can never be out of mind. The emblem as a whole is split into two halves, the Romulusside, on the left, colored in blood-green to symbolize aggressive strength and passion; the right-hand side, featuring Remus, rendered an icy blue. The image of the Eagle is mirrored in the design of Romulan warships, which are known as "Birds-of-Prey" or "Warbirds". Subordinate warriors within the military, especially young cadets, are also frequently referred to as "Eaglets".
The Romulan Star Navy, also known as the Romulan Imperial Fleet or Grand Fleet, is the militaryforce of the Romulan Star Empire. The Galae s'Shiar, (Romulan Star Navy or Imperial Romulan Fleet) is the largest branch of the Star Empire military. The department oversees shipping, including both domestic and military defense and assaults, on both the surface and space as well as exploration, engineering advancement, and the pursuit of the sciences. It is the largest branch in the military, having its own ground-based and intelligence forces.
The Tal Shiar is a Romulan intelligence organization. The name is an homage to the Tal Shaya, a Vulcan method of execution from the original Star Trek series where the neck is broken with a swift stroke for a quick and merciful death. This elite Romulan intelligence agency - the Tal Shiar is a highly-respected and feared force in the Romulan Star Empire, Alpha and Beta Quadrants. Its purpose is guarding the security of the Empire, both from the Romulans' interstellar enemies (most notably the United Federation of Planets and the Klingon Empire) and from traitors within the Romulan population itself. The covert, often invisible presence of the Tal Shiar keeps the general populace in a constant state of paranoia, that any signs of dissent or dissatisfaction with the status quo will result in their "disappearance." The Tal Shiar reports only to the highest levels of the Romulan government, and even so they undertake many missions without the direct knowledge of the Romulan Senate, conducting operations with virtual impunity throughout the Empire. Their authoritysupersedes that of most Romulan military commanders, resulting in a mutual distrust and hatred between the two organizations. The Tal Shiar operates their own fleet, often to their own aims.
