The Geography of Violence | All Recorded Battles in History

» War is father of all, and king of all.
He renders some gods, others men; he makes some slaves, others free.
We must know that war is common to all and strife is justice,
and that all things come into being and pass away through strife. «
 
Heraclitus (c. 500 BC), Fragments 53 & 80.
