Irish Monasticism refers to the Christian monastic tradition that developed in Ireland from the 5th century onwards. It was characterized by the establishment of monasteries, which served as centers of learning, spirituality, and community life. Monks followed strict rules, often inspired by figures like St. Patrick and St. Brendan, focusing on prayer, work, and study. These monasteries became influential in preserving and transmitting knowledge, particularly through the creation of illuminated manuscripts, such as the Book of Kells. They also played a crucial role in spreading Christianity throughout Ireland and beyond, contributing to the broader Celtic Christianity movement.
