His writings remain seminal texts for early twelfth-century Capetian history, and his reconstruction of the Basilica of Saint-Denis, where he was abbot, was instrumental in creating the Gothic architecture style.

[note 1] Suger took up the oblate life relatively easily, and showed strong ability including in Latin and a firm grasp of legal matters.

[note 2] Suger began a successful career in monastic administration as he went on several missions for his abbey, which held land at several vantage points across the country.

[note 3] Suger found himself involved in significant events: in the same year, he was at the synod at Poitiers; in the Spring of 1107 to attend Pope Paschal II; in 1109, where he met Louis VI again as he sat a dispute between the king and Henry I of England, and; in 1112 at Rome for the second Lateran council.

The area was suffering as a result of Hugh III of Le Puiset's exploitation of revenues, with a series of disputes and failing alliances eventually led to Suger gaining experience on the battlefield.

[4] There is a complete gap in sources on Suger's whereabouts after he left Toury in 1112,[5] though he was likely advancing his monastic position alongside working on further negotiations.

He is chosen as the royal envoy to welcome the fleeing Pope Gelasius II (John of Gaetani) to France and arrange a meeting with Louis VI.

[note 6] He urged the king to destroy the feudal bandits, was responsible for the royal tactics in dealing with the communal movements, and endeavoured to regularize the administration of justice.

After the regency, Louis VII and his contemporaries still consulted Suger on matters ecclesiastical and political, and he was asked to defend in a number of cases at court.

[8] Support for this fell apart from many churchmen, including the Pope losing belief in the pursuit and advising the king to remain in France to settle local issues.

Odo of Deuil's appointment as abbot had the backing of Louis VII and Suger, though after the two left, it was met with violent resistance by the canons (as was the case at Sainte-Geneviève).

The Abbey of Saint-Denis was, even prior to Suger's abbacy, a significant site, with a long tradition of royal burials dating back to the sixth century.

He designed the façade of Saint-Denis to be an echo of the Roman Arch of Constantine with its three-part division and three large portals to ease the problem of congestion.

[citation needed] At the completion of the west front in 1140, Abbot Suger moved on to the reconstruction of the eastern end, leaving the Carolingian nave in use.

[19] Suger's works served to imbue the monks of St Denis with a taste for history and called forth a long series of quasi-official chronicles.

The influence of the cosmology of the Chartres school, which resulted from interpretations of Plato and the Bible, created a speculative system which emphasised mathematics, particularly geometry, and the aesthetic outcomes that arise from the convergence of the two.
