The Gilbertine Order of Canons Regular was founded around 1130 by Saint Gilbert in Sempringham, Lincolnshire, where Gilbert was the parish priest. It was the only completely English religious order and came to an end in the 16th century at the time of the Dissolution of the Monasteries. Modest Gilbertine revivals have taken place in the late 20th and early 21st centuries on three continents.

Alexander of Lincoln was a medieval English Bishop of Lincoln, a member of an important administrative and ecclesiastical family. He was the nephew of Roger of Salisbury, a Bishop of Salisbury and Chancellor of England under King Henry I, and he was also related to Nigel, Bishop of Ely. Educated at Laon, Alexander served in his uncle's diocese as an archdeacon in the early 1120s. Unlike his relatives, he held no office in the government before his appointment as Bishop of Lincoln in 1123. Alexander became a frequent visitor to King Henry's court after his appointment to the episcopate, often witnessing royal documents, and he served as a royal justice in Lincolnshire.
