Holy crap, this is awesome. I can’t believe I just stared at my screen for 11 full minutes. Just imagine if this was an interactive map where you could hover over for more information, pan and zoom around. It’d be the coolest thing ever.
EDIT: Dammit, the idiots who apparently don't love free publicity took down the long version. The short version (sadly without dates or significant events called out) got taken down too. I found it on this site, see it while you can.
