Might is right

This concept is very ancient and appears in various forms in the works of Homer, Hesiod and in Plato (c.428-348 BC) The Republic, Book I, against which Socrates argued. Later Roman writers like Livy also took up the theme, as well as many medieval scholars and poets, most notably Walther Von Der Vogelweide (c.1160-1320) the German lyric poet, who wrote, “Might is right and justice there is none”. The expression first appears in English from the mid-18th century onwards.
