How do develop into a Kingdom

[Arceus Maximus]

How do I develop my barbanrian nationinto a kingdom?

I'm playing as the danes and have conqured some of Britain and I just wondered how I develop..

You either wait some years or you capture enough provinces (5+) to become a Kingdom. Remember that, as a Barbarian, you do not pay to raise troops, they show up automatically on your horde...on the other hand, to control a province, you must have troops in them (if you leave, you lose control)
