The Presider of the Worlds of the First Quadrant was the head of government for the Confederacy of the Worlds of the First Quadrant. The presider's seat was on the First World, the preeminent planet of the Confederacy.
In January 2382, the presider invited representatives of the United Federation of Planets to a diplomatic assembly on the First World, and intended to welcome the Project Full Circle delegation personally. Captain Chakotay informed Vice Admiral Kathryn Janeway that the personal involvement of the presider on such an occasion was a rare honor. (VOY novel: Protectors)
