If you look at the map of the world today, you’ll see over 190 nations, all with clearly defined borders.
Italy, for example, is on the edge of the Mediterranean Sea, and it is shaped like a boot. It all seems neat, tidy and squared away.

Throughout the entire course of human history, there have been huge shifts in power, cultural changes, dramatic invasions, and borders redrawn over and over.
