I am a mere mortal who has just developed some interest for World History. How most of the nations got where they are now. How they got their names etc. I know it is a huge subject but can you suggest me some good documentaries, movies, or TV shows I should watch?
Try Crash Course: World History's playlist on YouTube. Very interesting and entertaining. Its not very in depth but it covers up most of the timeline.
The Day The Universe Changed. Ties together a lot of history, interweaving events that are often studied separately, thus losing the sense of their influence on one another.
Not something you can watch but I actually think Ian Morris' Why the West Rules—For Now, whilst not really intended as such, actually offers a really entertaining whizz-stop tour through a good chunk of history and serves as a really good introduction to quite a lot of topics. Not sure if this is what you're looking for but I do really strongly recommend checking it out, its a great book.
