Cultural traits are for Civilization players.
England had good kings/queens when it had too. They played a big role in many things.
It is on an island. Very important.
And they had luck.
Trying to say "French are like this, German like that, etc." is pointless.
Attempting to reduce peoples to hats (or caps, if you understand Swedish history) is at best a futile exercise that does not do them dignity.
Other countries also had good rulers. I think England benefited more from a shortage of disasterously bad ones than from having good ones, over all.
Yeah, they were lucky that their Charles II was far more competent than Spain's monarch of the same name. Plus, Parliament was enough of a counterweight to royal misadventures, and the English Civil War showed that Parliament was the ultimate boss of the land.
