In the story's of Harry Potter for example:
Harry's train ride is an example of children on orphan trains in the united States being transferd from urban to rural places.
Dumbledore's demeanor and diplomatic wisdom resembles that of Sir. Winston Churchill.
The story's also parrallel Cold War Themes of evil, power, threats, devestation and division. Like countries, people are conquerd, controlled and devoured by evil powers as represented by Ginny, saying that the heir of Slytherin "took me over." Because he is a warewolf, Lupin was denied employment and blacklisted like the McCarthy-era communists, and he acted like a World War II conspirator by remaining passive and justifying his silence. sirius Black could be misunderdtood and falsley acussed like "The man in the Iron Mask," exiled like nepoleon, traped like the princess in the tower or like a prisioner of war for example. These are just a few ideas that taugh me alot in writing.
