What is the term for an assembly of delegates chosen for one session?

The term "convention" refers to an assembly of delegates who come together for a specific purpose, typically for a defined session or period. Conventions are often formal gatherings organized by organizations, associations, or political parties to conduct business, discuss policies, or make decisions that affect the group as a whole. This term is particularly relevant in contexts where representatives from various regions or groups convene to address issues pertinent to their collective interests.

In contrast, other terms like "conference," "summit," and "forum" may refer to gatherings and discussions but do not specifically define the assembly as being comprised of delegates chosen for an individual session. A conference might have a broader scope, often covering multiple topics over several days. A summit typically involves high-level meetings or discussions among leaders. A forum can refer to any gathering for discussion, which could include a more casual exchange rather than the structured assembly inherent in a convention. Thus, "convention" is the most precise term for an assembly of delegates gathered specifically for one session.
