The Delcontrian faction functioned as a delegation within the Galactic Senate of the Galactic Republic throughout the Republic Era. During 32 BBY, this group initially cast their votes in conjunction with the Trade Federation concerning a suggested taxation bill. However, this alliance shifted when Senator Palpatine representing the Mid Rim planet Naboo—who was secretly the Dark Lord of the Sith Darth Sidious, and the hidden manipulator of the Trade Federation—demanded the inclusion of a bypass amendment. This amendment ultimately led to the Trade Federation losing the support of the Delcontrian faction. Sidious, who from the start wanted the bill to fail, was satisfied with the insights gained regarding various Senate groups through observing their actions related to the bill's defeat. Despite Viceroy Nute Gunray's doubts, Sidious assured him that the Delcontrian faction would soon introduce a fresh proposal.
The Delcontrian faction receives a mention within Queen's Peril, a young-adult novel penned by E. K. Johnston and published in 2020.
