A still-existing order of fratres cruciferi, which literally means "cross wearers", had its mother house outside of the city of Huy in Belgium. Founded in the early 1200s, it spread into France, Germany, the Netherlands, and England during the next two centuries. Its founders are identified as five men who accompanied the prince-bishop of Liege, Radulf von Zahringen, in 1189-1191 as part of the Third Crusade. Upon their return, the five sought a new way of life and were appointed canons of the cathedral by their bishop shortly before his death. In the years which followed they several times sought to reform and renew the life of the cathedral canons. Later they retired upriver to the city of Huy and to a place on a hillside outside the town known as Clairlieu. There they five formed a community and sought a more intense spiritual life. In either 1208 or 1210 Pope Innocent III approved their manner of life, directing them to live according to the Rule of St Augustine. Although they referred to themselves as the Brethren of Holy Cross, and their foundation was contemporary with the groups of Saint Francis and Saint Dominic, they were not friars. They were, and remain, a community of canons regular. As such, their members are for the most part priests, who live a common life, engage in the traditional daily round of liturgical prayer, and devote themselves to some form of active ministry. They also wear a religious habit which reflects their canonical origins, namely, a white soutane or tunic, a black pendant sash, a scapular with a red-and-white Maltese cross over the heart, and a black mozetta or elbow-length cape, which remains unbuttoned and open to reveal the cross. Modern descendants of these Brethren are known as Kruisheren, Kreuzherren, Croisiers, and Crosiers.
Like other religious orders, the Crosiers have known periods of growth and vitality and periods of decline in their eight-hundred-year history, and will point to the 1400s and 1600s as their times of greatest energy and growth. Their most difficult years came in the wake of the French Revolution and Napoleonic era, however, when nearly all their monasteries were closed and their members banished from them. They did not, however, become extinct, as some sources claim. In 1840, there remained only four elderly members, living in the monasteries at Uden and near Cuijk, both in the Netherlands. In that year, the Dutch king, Willem II, repealed his father's law forbidding religious orders in his kingdom to receive novices. The Order slowly recovered over the next decades and, in the early 1900s, began to spread outward from its small European base in the Netherlands and Belgium to the United States, Brazil, Indonesia, and the Congo. Crosiers still live and work in all these places and today number about five hundred members.
Other Fratres Cruciferi were also to be found in Bohemia in the thirteenth century and some said to have existed in Ireland, but there is practically no reliable information to be obtained about them.
