The Middle Ages was filled with things like Kings, hierarchies that includes where you stand in society(peasants and what not).

During the Middle Ages transportation was either horses, carts and/or feet. Now we use cars, planes, boats, sometimes horses and carts in some places, etc. and as you can see we now have phones and technology, something the Middle Ages did not have.I did my best to answer, I hope this helped...
