When did the people in Canterbury set off on pilgrimages?

The people in Canterbury set off on pilgrimages primarily during the medieval period, particularly after the martyrdom of Archbishop Thomas Becket in 1170. His shrine in Canterbury Cathedral became a major pilgrimage destination, attracting thousands of pilgrims from across England and beyond. The practice flourished throughout the 12th to the 15th centuries, with pilgrims seeking spiritual healing and penance. Pilgrimages to Canterbury were notably popularized in Geoffrey Chaucer's "The Canterbury Tales," written in the late 14th century.
