Coligny, along with many other Calvinist nobles, arrived in Paris for the wedding of the Catholic princess Margaret of France to the Protestant prince Henry of Navarre on 18 August 1572. On 22 August, an assassin made a failed attempt on Coligny's life, shooting him in the street from a window. While historians have suggested Charles de Louvier, sieur de Maurevert, as the likely assailant, historians have never determined the source of the order to kill Coligny (it is improbable that the order came from Catherine).
