The History of Rome, written in approximately 27-25 BCE, is the best-known work of the Roman historian Titus Livius, known in English as Livy.
Even two millennia ago, Livy understood the importance of the rule of law. At the start of Book Two, he characterizes a free nation as one that is governed by annually elected officers in which the rule of law, rather than the caprice of individual men, serves as the ultimate authority.
In other words, No Kings.
