Right, I didnt realize that Germany was composed of so many different "local areas or lords" compared to other countries like the UK. But most likely they shared common languages and cultures. I guess the map of UK didnt break them down into different subsets because the local leaders may have fell under one united king.

And to be honest my knowledge pre WWI Germany or rather the area that is now called Germany is pretty lacking. They taught more about France and England from what I remember in grade school history.
