The Rulers throughout European History?

I understand this is a very broad question to ask: but after reading in depth about France's prominent rulers, (namely Marie Antoinette) I've become very interested in the different dynasties and stories behind countries and their kings/dictators/monarchies and so on and so forth. If you have any information you'd like to explain to me, or sites with perhaps family trees you could send my way it would be greatly appreciated. I'm taking AP European History this coming year so I'm not especially looking for current rulers; but namely rulers during the Medieval and Renaissance periods. But anything will suffice, I look forward to any information I recieve.
