A Cistercian is a member of the Cistercian Order (abbreviated as OCist, SOCist ((Sacer) Ordo Cisterciensis), or ‘’’OCSO’’’ (Ordo Cisterciensis Strictioris Observantiae), which are religious orders of monks and nuns. They are also known as “Trappists”; as Bernardines, after the highly influential St. Bernard of Clairvaux (though that term is also used of the Franciscan Order in Poland and Lithuania); or as White Monks, in reference to the colour of the "cuccula" or white choir robe worn by the Cistercians over their habits, as opposed to the black cuccula worn by Benedictine monks. The original emphasis of Cistercian life was on manual labour and self-sufficiency, and many abbeys have traditionally supported themselves through activities such as agriculture and brewing ales. Over the centuries, however, education and academic pursuits came to dominate the life of many monasteries. A reform movement seeking to restore the simpler lifestyle of the original Cistercians began in 17th-century France at La Trappe Abbey, leading eventually to the Holy See’s reorganization in 1892 of reformed houses into a single order Order of Cistercians of the Strict Observance (OCSO), commonly called the Trappists. Cistercians who did not observe these reforms became known as the Cistercians of the Original Observance. The term Cistercian (French Cistercien), derives from Cistercium, the Latin name for the village of Cîteaux, near Dijon in eastern France. It was in this village that a group of Benedictine monks from the monastery of Molesme founded Cîteaux Abbey in 1098, with the goal of following more closely the Rule of Saint Benedict. The best known of them were Robert of Molesme, Alberic of Cîteaux and the English monk Stephen Harding, who were the first three abbots. Bernard of Clairvaux entered the monastery in the early 1110s with 30 companions and helped the rapid proliferation of the order. By the end of the 12th century, the order had spread throughout France and into England, Wales, Scotland, Ireland, Spain, Portugal, Italy, and Eastern Europe. The keynote of Cistercian life was a return to literal observance of the Rule of St Benedict. Rejecting the developments the Benedictines had undergone, the monks tried to replicate monastic life exactly as it had been in Saint Benedict's time; indeed in various points they went beyond it in austerity. The most striking feature in the reform was the return to manual labour, especially agricultural work in the fields, a special characteristic of Cistercian life. Cistercian architecture is considered one of the most beautiful styles of medieval architecture. Additionally, in relation to fields such as agriculture, hydraulic engineering and metallurgy, the Cistercians became the main force of technological diffusion in medieval Europe. The Cistercians were adversely affected in England by the Protestant Reformation, the Dissolution of the Monasteries under King Henry VIII, the French Revolution in continental Europe, and the revolutions of the 18th century, but some survived and the order recovered in the 19th century.
