In the 1080s, Sélestat was the property of Hildegard von Eguisheim, mother of Frederick I, Duke of Swabia, the first member of the House of Hohenstaufen. Hildegard transformed the place into a religious centre when she founded St. Faith's Church, which she gave to the Benedictines of Conques Abbey. Monks from Conques opened a priory next to the church in 1092. The House of Hohenstaufen quickly became the leading dynasty of the Holy Roman Empire, which came to the imperial throne in 1152. Being under their protection, the priory of Sélestat strongly influenced local life. Even though Sélestat constituted a distinct parish, its priest had only limited power and the Benedictine prior was the true head of the municipality. At the end of the 12th century, the Hohenstaufen dynasty gradually lost power and as a result the priory started to decline. The citizens used this opportunity to reduce the prior's dominance and secure the power of their parish. They started to build a new parish church in the 1220s. St. George's Church was designed in Gothic style and was significantly larger than St. Faith's Church, another way to signify the end of Benedictine hegemony.
