I'm sorry ahead of time.
A reporter named Dan Carlin does a podcast every few months called 'Hardcore History.' While he is not a historian, it truly seems he tries to deliver very accurate information, with some pazaaz. This guy makes history SO INTERESTING AND INTENSE. He mostly focuses on military history. He's done several epic show series including the fall of the Roman Empire. (12+ hours on it) All chronologically. Love Mongolians? Want to learn their amazing history for 6-8 hours? Wanted the facts about Hannibal's assault on Rome (Though it was more about separating Rome from it's Italian allies)? Punic wars are for you. Interested in WW1? The series he is currently working on 'Blueprint for Armageddon' is in the process of covering it.
I cannot stress how great his show is. I wasn't particularly interested in history until I started listening to it. He keeps a rolling list of free shows, and the ones you have to pay for are 1.00-3.00 USD.
http://dancarlin.com/disp.php/hharchiveI suggested starting 'The Wrath of the Khans.' It is by far my favorite, and still free! The reason why I'm sorry is... he takes 4-6 months for new episodes of hardcore history to come out. SUCH A LONG WAIT.
