A person who calls together or convenes a group of people for a meeting or assembly.
From Latin convocator, derived from convocare (to call together), combining con- (together) and vocare (to call). The word evolved in medieval usage to refer to officials who summoned gatherings, particularly in religious and academic contexts.
Convocators were crucial figures in medieval universities and church councils—without them, you couldn't have important meetings because they literally had to go around announcing that everyone needed to gather. It's like being a professional announcer, except for something as serious as deciding matters of law or theology.
