Apologies for the wide timeframe and unspecified setting. Any examples at all are fine. Would queens ever take a hand in ruling or administration? Would a personable queen ever serve as a diplomat for interactions with vassal lords?

How effective would a WWII era 37 mm anti-tank cannon or larger be at destroying a current tank like an Abrams? Would the cannons on the tanks in WWII be of an use against a modern one?

Been trying to find some papers/books on the whole 'give no quarter' that the Swiss have used over the years. Help me!

In terms of bullet resistance, shrapnel resistance, utility (boil water) etc which helmets were the most effective in each particular role and which helmet was the best to wear if you wanted to live longer?

I realize that there isn't much material available on this topic, but I'd appreciate any input.

I've been curious for a long time now on wen we as a people began being interested and even obsessed with other peoples lives; specifically people who star in movies or are on the cover of a magazine.

This is sort of a broad question, but I'm interested in how exactly the mongols came to become so dominant.

The impression I have from what little I've learned about them is that the mongols basically swarmed in with massive amounts of horse archers with little regard to tactics aside from 'shoot at enemy while riding towards them, run away when the enemy pursues, ride back towards them while shooting, repeat until enemy is dead or fleeing'.

Is this correct? If so, where did there get all the horses from? I remember reading that in europe horses were very expensive to breed and raise, and so only the wealthy nobles had access to them, who formed the bulk of medieval cavalry. So how is it that all of the mongolian soldiers had their own horses to ride?

The wikipedia articles on the matter are long and rather unclear, so I was hoping someone could provide a clear and concise summary of how the Dutch Republic functioned.
Further, how well did it function?
Did the republic get bogged down by arguments between it's representatives, and if so, what caused this and how could it have been prevented?

I apologise for naming such a vast and relatively vague period of time, but I have been playing EU IV lately, and I was thinking about how horribly things can go wrong with so much information.

How did rulers "see" the world? How much information did they have on everything? What helped them make decisions, in terms of stats and maps? Or was most of it dealt with in a much more delegated sense?

I'm vaguely aware of the home guard and 'dads army' esque resistance but I've never really heard about the extent of defending the uk against a d-day style German invasion.

I know how controversial and opinionated this question has the potential to be, but still, this should be interesting.
