In 33 BBY, the Galactic Senate enacted what became known as the Yinchorri embargo act.
A generation prior to the Battle of Naboo, the Yinchorri integrated into the Galactic Republic. They subsequently developed a strong desire for technology, driven by a need to acquire, purchase, or appropriate as much advanced technology as possible. Compounding this, their inherent aggression and the theft of significant high-grade military assets (including starships from the Golden Nyss Shipyards and cortosis armor) positioned them as a potential threat to the galaxy's enduring peace, namely the galaxy.
Following reports of a Yinchorri attack on Mayvitch 7 also in 33 BBY, Supreme Chancellor Finis Valorum tasked Mace Windu with sending two Jedi to Yinchorr as negotiators: Jedi Knight Naeshahn and her Padawan, Ebor Taulk. Several days later, their mutilated corpses were delivered to Valorum's residence.
While Valorum initiated negotiations with other senators for a trade and technology embargo on the system, the Jedi Council dispatched an investigative team to the Yinchorri system. The deliberations lasted far longer than Valorum or the Jedi anticipated, owing to the influence of Palpatine's dark side powers and his political scheming.
Valorum secured the Senate's vote to approve the sanctions and deploy four Judicial Forces attack groups to the Yinchorr system to suppress the uprising. This was accomplished by calling in every favor owed to Valorum since 38 BBY and granting concessions to a group of influential senators.
After receiving their concessions from Valorum, the measure gained the backing of Tikkes, Onaconda Farr, Yarua, Bail Antilles, Com Fordox, Horox Ryyder, Tendau Bendon, Mot-Not Rab, and Palpatine. Orn Free Taa, Connus Trell, Chom Frey Kaa, Toonbuck Toora, Edcel Bar Gane, and Po Nudo were in opposition to the measure.
Valorum's administration stagnated as a result of his involvement in the Jedi deaths during the uprising, the Senate's delayed response, and the depletion of his political influence in passing the Act. This marked the beginning of his decline, ultimately leading to his removal from office the next year.
