I'm British and got it wrong, I knew he would be the opposite of Charles I but I couldn't remember if Charles was a catholic or protestant. I knew Elizabeth and James were both protestants so I (incorrectly) guessed Charles was as well.
Except that England's religion has, since Henry VIII, been *very specifically* Church of England. Other sects of Protestantism have been variously considered different or even excluded from public life.
I only got it because Charley 1 chartered my home state, Maryland, as a "Catholic Proprietary." There's still a significant Catholic presence here, though not the majority it once was.
great quiz. would be nice if 6, 9 and 12 had some explanation show up at the end, like many of the others do. e.g. what cities? and what was the name of the first Channel swimmer? (obviously i can find these out myself, but i always like it when it's included in the quiz)
And @branlito, I am one of those who thought the first person to swim the channel was a woman - specifically, Gertrude Ederle.
