Anyone know why castling out of check isn't allowed? afterall, you can move out of check, and isn't castling a type of move?

I'm not suggesting the rules should be changed, just wondering if there's a reason for the rule or if it's just one of those things lost to history...

Great question!  I'm interested to find out as well...

Because the rules were written that way...

Thankyou for your informative opinion; perhaps it would have been more succinct to have merely stated that you didn't know? What I am trying to find out is WHY the rules were written that way...

I don't know either. Perhaps it has something to do with the fact that a castling move also involves moving a rook and allows a king to move 2 spaces with one move.

Check the history section here. I am not sure how reliable it is but I have read similar articles before.
