british vs french and their indiginous allies, before there was a u.s. one of my own ancestors was a titular head of the 'military contractors' (they were called mercinaries in those days) hired by the british, from the principality of hess. wars draw boundries on maps, but they don't create the world we experience living in. i don't 'get' why historians are so obsessed with them, other then, having usually a clear time frame, that makes it easy for them to point to.
