A general is indeed required for every army you have, yes. When you reach the next Imperium level, your faction's cap will increase, allowing you to create more armies, fleets and agents. You do this mainly by conquering, and conquering entire provinces rather than isolated settlements seems to add more (Or at least that's what I've observed). To increase your faction's limits on armies, fleets and agents, you need to increase your Imperium level. And also, do you need a general for every army, if not how do u raise them? When i play i capture city after city but i can only enlist max 4 armies and 4 fleets.
