The thing is, there has always been stuff happening, somewhere in the world.french history in 1775 might be boring, but Spanish history of the same year are-grabbingly exciting. If you get high on the evolution of intercultural relations then a long era of peace, trade and communication will be for you, whereas if you like gore, horror and devastation then the same era won't appeal... Quite so much.
It's been said already, oi nose.
I also find the macro historical trends interesting. Compare how over the centuries China developed into a massive, multilingual and multicultural empire/nation, whilst Europe or Africa or the middle East developed into a collection of independent, often mutually opposed little countries/nations.
