By 1413, Christine composed Livre de paix, advising French rulers on just governance amid political turmoil.
By 1413, Christine de Pizan had composed Livre de paix (The Book of Peace), a political treatise addressed to the future Charles VII (then Dauphin) offering guidance on wise, just, and peaceful governance during a period of severe internal strife in France.
Written amid the destabilizing Armagnac-Burgundian civil conflict and the looming threat of renewed English aggression during the Hundred Years' War, the treatise drew heavily on the model of Charles V, whose biography Christine had written years earlier. She emphasized the responsibilities of a ruler to maintain justice, avoid unnecessary conflict, and govern with prudence and moral integrity.
This work is significant as further evidence of Christine's standing as a political advisor whose counsel, though delivered through the medium of literature, was directed at the highest levels of the French monarchy. Few women of her era were afforded any platform to comment on statecraft, yet Christine's established reputation as a scholar and moralist granted her a degree of access and authority unusual for a woman writer.
The Book of Peace reflects the culmination of Christine's decades-long engagement with questions of governance, chivalry, and civic virtue, and it stands as a testament to her role not merely as a literary figure but as a genuine political thinker whose works sought practical influence over the fate of the French kingdom.
