International borders have carved up the world in a thousand different ways. But while they seem like permanent fixtures, international borders don't actually exist. Rather they are human-made constructs that tell us where we can or can not go. And not all that long ago, borders didn't really exist at all, at least not in the way we think of them now. Join Geoff and Hunter as they explore the history of borders and what they mean for people all over the world!
