Italy, Pepin gave the monastery privileges, letters of protection, and an assured income. Pepin placed the rule of St. Benedict in the hands of St. Otmar (to be substituted for that of St. Columban). Otmar (or Othmar) is named as the founder and the first abbot of the Abbey of St. Gall. During his abbacy the St. Gall School was founded. Otmar extended St. Gall's original hermit cell and adopted the Carolingian style for his building projects. The abbey grew quickly; many Alemannic noblemen entered to become monks and arts, letters and sciences flourished. The register of monastic professions, at the end of abbot Otmar's rule makes mentions of 53 names. Two monks of the Abbey of St Gall, Magnus of Füssen and Theodor, founded the monasteries in Kempten and Füssen in the Allgäu. With the growth in the number of monks the abbey also grew economically stronger. Much land in Thurgau, Zürichgau and in the rest of Alemannia as far as the Neckar was donated to the abbey by means of Stiftungen. Under abbot Waldo of Reichenau (740–814) copying of manuscripts was undertaken and a famous library was gathered. Numerous Anglo-Saxon and Irish monks came to copy manuscripts. At Charlemagne's request Pope Adrian I sent distinguished cantors from Rome, who instructed the monks in the use of the Gregorian chant. In 744, the Alemannic nobleman Beata sold several properties to the abbey in order to finance his journey to Rome. Golden Age In the subsequent century, St. Gall came into conflict with the nearby Bishopric of Constance which had recently acquired jurisdiction over the Abbey of Reichenau on Lake Constance. It was not until Emperor Louis the Pious (ruled 814–840) confirmed in 813 the imperial immediacy (Reichsunmittelbarkeit) of the abbey, that this conflict ceased. The abbey became an Imperial Abbey (Reichsabtei). King Louis the German confirmed in 833 the immunity of the abbey and allowed the monks the free choice of their abbot. In 854 finally, the Abbey of St Gall reached its full autonomy by King Louis the German releasing the abbey from the obligation to pay tithes to the Bishop of Constance. From this time until the 10th century, the abbey flourished. It was home to several famous scholars, including Notker of Liège, Notker the Stammerer, Notker Labeo, Tuotilo and Hartker (who developed the antiphonal liturgical books for the abbey). During the 9th century a new, larger
