Autocrat
An autocrat is the chief organizer of an event. Typically, they make arrangements for renting a site, filling in and filing event forms, advertising the event, handling emergencies at the event, and handling the event finances and final reporting. If the event is small, the autocrat may do everything. If the event is large, the autocrat will pull together a team.
(Another definition, gleaned from another page.) Autocrats are the event organizers of the SCA. They are the overall head of an event, be it a huge multiweek event with thousands of people attending, such as Pennsic, or a small, 20 person, canton demo. Both the power and responsibility of an autocrat is vast and so to are the hours that a good autocrat will put into the event that he or she is planning.
In the Principality of Tir Righ, the term Event Steward has begun to replace the word Autocrat.
