Explanation: All powers were vested in the king. Inscriptions do not specifically speak of a council of ministers, but they do refer to an official called maha-sandhi-vigrahika.

Four other categories of ministers are also referred to in the epigraphs: Pradhana (head minister), Mahasandhi-vigrahika (minister of foreign affairs), Amatya (revenue minister), and Samaharta (minister of exchequer).
