• To hear petitions or grievances: A king might hold court to listen to complaints from his subjects and dispense justice.
• To celebrate victories or mark important events: Meetings could be called to commemorate military successes, royal births, marriages, or other significant occasions.
• To consolidate power or seek support: A king might gather nobles, clergy, or other powerful figures to solidify his authority or gain backing for his policies.
• To address crises or emergencies: In times of famine, plague, rebellion, or invasion, a king would likely call a meeting to coordinate a response.
