What is "premonstratensians"

The Order of Canons Regular of Prémontré, also known as the Premonstratensians, the Norbertines and, in Britain and Ireland, as the White Canons (from the colour of their habit), are a Roman Catholic religious order of canons regular founded in Prémontré near Laon in 1120 by Saint Norbert, who later became Archbishop of Magdeburg. Premonstratensians are designated by O.Praem. (Ordo Praemonstratensis) following their name.

Norbert was a friend of Saint Bernard of Clairvaux and so was largely influenced by the Cistercian ideals as to both the manner of life and the government of his order. As the Premonstratensians are not monks but canons regular, their work often involves preaching and the exercising of pastoral ministry; they frequently serve in parishes close to their abbeys or priories.
