First foundation On 28 June 1062, an hermitical fraternity was founded in Affligem by six knights who repented of their violent way of life.
Hermann II,
Count Palatine of
Lotharingia (1061–1085) and his guardian,
Anno II, archbishop of Cologne (d. 1075) donated the foundation grounds. On this land, the first abbey church, dedicated to
Saint Peter, was erected in 1083. The
Benedictine Rule was adopted in 1085, followed by the formal dedication of the abbey in 1086. The first abbot of the abbey was Fulgentius (1088–1122), a monk of Saint-Vanne Abbey in Verdun, originally from
Frasnes, in
Walloon Brabant.
John Cotton, whose
De musica (c. 1100-1121) is one of the earliest musical theses, is also referred to as ' Johannes Affligemensis' because he dedicated
De musica to abbot Fulgentius. The counts of
Brabant, also counts of
Leuven, became their protectors (
Vögte) in 1085/1086. A number of their family members are buried in the abbey church, including Queen
Adeliza of England (d. 1151), as well as her father Duke
Godfrey I of Leuven (d. 1139). Queen Adeliza was buried in the abbey church in 1151, near the clockwork. During the 12th century, the abbey became known for the strict adoption of the
Cluniac observance. Several monasteries were founded by the monks of Affligem or assigned to the abbot of Affligem by their founder.
Maria Laach Abbey in the
Rhineland-Palatinate in Germany, was founded in 1093 as a priory of Affligem by the first Count Palatine of the Rhine
Heinrich II von Laach and his wife
Adelaide of Weimar-Orlamünde, widow of
Hermann II of Lotharingia.
Bernard of Clairvaux visited Affligem in 1146, where it is said his greeting to the
Blessed Virgin was miraculously answered. Affligem Abbey is a member of the Flemish Province of the
Subiaco Cassinese Congregation within the
Benedictine Confederation. ==Building history==
