What is your favorite part of history to read/learn about?

besides my obvious obsession with NOLA history, it has to be ancient Greece and Rome. Before the History channel fell apart completely I used to love any show concerning the engineering or philosophy of those cultures. Last year I read several books surrounding WW2 including Rise and Fall of the Third and "The 2nd World War" Also, I have the World at War Documentary series and have only watched the first 5 so far. Definitely getting back to those. It is hard to believe that a series done in 1973 was so well done.
