The court was the centre of administration, representing at once executive, legislative and judiciary branches of the government. The members of the court can be divided into three general categories: royalty, ministers, and subordinate officials. At the top were the high king, princes, princesses, queens and concubines. The ministers were usually drawn from more distant branches of the royal family. Their subordinates were not royal but usually hailed from top official families. Titles, ranks, insignia, fiefs and other such rewards helped maintain the loyalty-patronage structure of the court.
