User blog comment:Mr Rinn/My thoughts on what era Assassin's creed IV could be in/@comment-3168501-20121112073333

Any of the major world powers would be great: ancient Egypt, Medo-Persia, Greece, Babylon, Rome-we've alredy touched on the Anglo-Saxon world power in AC3, well before England and the U.S came together. WWII is when they collaborated, but that'd be too...expected. Just remember: the conflict has to be large enough to camouflage the Assassin-Templar war happening at the same time.

To the Anon below, slavery is a touchy subject; however, they did use it as a backdrop for Liberations. The Civil War would be the pinnacle of that issue but the lines would be clearer as far as Assassins and Templars are concerned. I can't remember if Templars looked at economic advantages or not; if so, they'd view slavery as a means to an end-that end being money. If Connor's reaction was foreshadowing, it'd have to be his descendant fighting in the war; it doesn't take place until the 1860s, over a hundred years since his birth.
