What were the official duties of the consuls? What did they do?

Both consuls had equal power. They recruited the army, convened the National Assembly, and could propose new laws. Each of them had the right to cancel the order of the other, so the consuls had to make collegial decisions. During the military campaign, one consul commanded the army, the second was in the city. In the event of a dangerous situation, both consuls alternately commanded the army.
