This collective noun is "a parliament of dukes." Derived from the English parliamentary tradition where representatives gather to debate and make decisions, the term "parliament" is adopted to depict a gathering or assembly of dukes. It reflects the distinguished and influential nature of these aristocratic individuals, suggesting that their gatherings have the potential for vital discussions regarding important affairs. "A parliament of dukes" conveys not only the idea of a physical gathering of these noble individuals but also implies a certain level of power, influence, and collective wisdom associated with their meeting.

The notion of a parliament of dukes is inherently abstract yet evokes a sense of awe and authority befitting their privileged status. It raises visions of opulent chambers where intellectual debates, diplomatic negotiations, and political maneuvers between powerful figures take place. The engagement of multiple dukes in such strategic conversations illustrates the significance and weight that these aristocratic individuals bear in matters pertaining to governance and monarchy. In summary, using the collective noun "a parliament of dukes" offers a vivid and descriptively rich way to conceptualize the coming together of dukes. It conveys not only their group cohesion and shared interests but also acknowledges their influential roles within the feudal and aristocratic structures of society.
