Antoine de Croy, Prince de Pocien

Antoine III de Croÿ, Prince de Porcien (1540-1567) was a French noble and Protestant rebel. Porcien, who held the rank of prince through his sovereign possessions, was a member of the Croÿ family. In 1558 his mother converted to Protestantism, and he followed her in 1560. His house, de Croÿ had been close with the Guise who used them as part of their broader rivalry with the House of Montmorency, supporting their claims that hurt their rival. Porcien broke with the Guise after his conversion. With the advent of Francis II's reign he joined Navarre in opposition to their house. The following year a strategic marriage was arranged for him with Catherine de Clèves which would bring him the County of Eu in 1564.
