Trêve de Dieu
The concept of Pax Romana was highly influential, and attempts to imitate it occurred in the Byzantine Empire, and in the Christian West, where it morphed into the Peace and Truce of God ("pax Dei" and "treuga Dei"). A theoretician of the imperial peace during the Middle Ages was Dante Aligheri. Dante's works on the topic were analyzed at the beginning of the 20th century by William Mitchell Ramsay in the book "The Imperial Peace; An Ideal in European History" (1913).
