I've seen two flags representing Scotland, one being a red lion on a gold field and a the other a white X on a blue field. Why is this?
The white cross on a blue background is our national flag, it is called The Saltire and is supposed to represent the cross of our patron saint (St Andrew) was crucified on.
The other one is The Rampant Lion and is the Royal Standard of Scotland. Historically the flag of the king or queen of Scotland, but since the union of the crowns there has been no explicit Scottish royal family.
