The agency dated as far back as 3,964 BBY where it operated during the Mandalorian Wars. At the time, Lhosan IndustrieschairmanJervo Thalien used his company's immense resources to consult with Republic Intelligence in order to determine the location of TarisSenatorHaydel Goravvus after his world had fallen to the Mandalorians. However, Republic Intelligence determined that the senator was still on Taris.[3] Following that conflict, Revan became a Dark Lord of the Sith and forged a new Sith Empire which consisted of many of his own followers included soldiers that had originally served the Republic. Republic Intelligence reports indicated evidence that the Jedi Order had suffered even greater casualties after the war, when the First Jedi Purge was being perpetrated, but the information remained classified until some time after the devastation of Katarr, so the dissolution of the Order became one of the greatest mysteries of that time.[8]
In the years leading up the the Great Galactic War, the Republic had made several attempts to operate a viable intelligence organization with peace time duties though they had had little success. With the resurgence of the Sith Empire and the start of the Great War, the Republic saw the need for a capable espionage agency. With most of the military intelligence dismantled, the Republic turned to the Strategic Information Service of the Senate Library. The SIS was reorganized and moved from its simple duties of decryption and monitoring duties under the Senate Library and transferred into a full fledged intelligence and espionage agency. Though technically a part of the military intelligence, it became the de facto central intelligence service of the Republic and served in this capacity throughout the Great War. It continued to gather intelligence on its intelligence counterpart during the Cold War standoff between the Sith Empire and the Republic.[5] At some point after the Cold War ended, the Republic dissolved the SIS and Republic Intelligence was reestablished later on along with the Senate Bureau of Intelligence.[1]
Republic Intelligence remained active through 32 BBY, when it was involved in watching the activities of the Trade Federation. Certain intelligence officers expressed the concern that the Neimoidians in charge of the Federation were taking control of outlying systems through deceitful or militaristic tactics. Once this was done, the Trade Federation would form exclusive contracts with the newly conquered world and enforce them with further threats of military action. In addition, the Federation had been keeping the Gungans of Naboo under observation, though knew little of the workings of their underwater cities or even the size of their Rep Council. In addition, intelligence agents reported pirate gangs on Naboo that dealt in the trade of stolen Shaak.[9] In the time following the Invasion of Naboo, Republic Intelligence was responsible for the examination of the Star Couriervessel that belonged to the slain Sith Lord known as Darth Maul. However, the intelligence agents made a mistake during the entry into the ship which led to the weapons, flight and communication systems on the ship self destructing. The remains of the damaged ship were left in a secret hangar on Theed where it remained for many years.[7]
Jedi MasterMace Windu made use of the organization's sporadic reports on Separatist activity on his homeworld of Haruun Kal in 21.5 BBY in order to track down the activities of fellow Jedi Master Depa Billaba who had been dispatched to the planet. Through intelligence's resources, Windu managed to uncover a report of a sabotage made against a Separatist starfighter base as well as the failure of the Balawai militia's attempts at eliminating Depa's resistance forces. At some point, Republic Intelligence received word that the Confederacy had pulled back its forces to the Gevarno Cluster and had left their base at Pelek Baw abandoned. Despite this being the case, there had been no sighting from Master Billaba which prompted concern from Master Windu. Later, an agent from the intelligence service reported to Grand MasterYoda, Master Windu and Supreme ChancellorPalpatine that Master Billaba had gone renegade on Haruun Kal. When Palpatine decided to send a Republic Intelligence covert team to the planet to apprehend Depa Billaba, Mace Windu decided that he would attend the matter personally. After arriving on Haruun Kal, Master Windu was accompanied by a planetary chief from Republic Intelligence though she was later killed during the operation. Following the success of the mission on Haruun Kal, Master Mace Windu aided in enlisting Nick Rostu into Republic Intelligence.[13]
At the closing stages of the Clone Wars, Obi-Wan Kenobi suggested to the Jedi Council that they focus the efforts of Republic Intelligence on locating General Grievous. On Utapau, Kenobi promised Tion Medon that he would file a report with the intelligence service in regards to the crisis on the planet.[15] By 19.5 BBY, Armand Isard served as director of Republic Intelligence.[16] With the Declaration of a New Order, Republic Intelligence became a part of the newly formed Imperial Intelligence.[4] Some resources were also allocated to the Imperial Security Bureau, the Empire's secret police.[17] Shortly after that, Lorz Geptun was charged by the agency to gather more information on the Jedi Rebellion though he later uncovered truths about the decimation of the Jedi Order that his superiors did not want known and Geptun defected to the New Republic.[4]
