Chief Executive The king was invested with supreme military, executive, and judicial authority through the use of imperium, formally granted to the king by the Curiate Assembly with the passing of the Lex curiata de imperio at the beginning of each king's reign. The imperium of the king was held for life and protected him from ever being brought to trial for his actions.

This made the king the head of the national religion and its chief executive. Having the power to control the Roman calendar, he conducted
