Well, I've been trying to put together the history of the world.
Like how, why and when did Romani people got persecuted, how did Genghis Kan went down on history, what were really like the Inca and Mayan empires, what were the most important wars that ever happened apart from war I and 2, how slaved ended and where it kind of didn't, what was it like the 50's segregation in USA, when and why the silk road came to be etc....
I'm trying to put together a lot and hopefuly plug the holes of my ignorance.
I know it's a lot to ask, but what books do you recomend to understand the big picture?
It can be big sum up, or different books, or a series... anything that you thik is mandatory read to really understand that stuff.
Have you checked out the Ask Historians Booklist? It has books on almost every place and time period you can think of. It sounds like you might be especially interested in the "General" section which gives some big over views.
