Carolingian Renaissance
The Ottonian Renaissance was a limited renaissance of logic, science, economy and art in central and southern Europe that accompanied the reigns of the first three emperors of the Saxon Dynasty, all named Otto: Otto I (936–973), Otto II (973–983), and Otto III (983–1002), and which in large part depended upon their patronage. Pope Sylvester II and Abbo of Fleury were leading figures in this movement. The Ottonian Renaissance began after Otto's marriage to Adelaide (951) united the kingdoms of Italy and Germany and thus brought the West closer to Byzantium and furthered the cause of Christian (political) unity with his imperial coronation in 963. The period is sometimes extended to cover the reign of Henry II as well, and, rarely, the Salian dynasts. The term is generally confined to Imperial court culture conducted in Latin in Germany. It is sometimes also known as the Renaissance of the 10th century, so as to include developments outside Germania, or as the Year 1000 Renewal, due to coming right at the end of the 10th century. It was shorter than the preceding Carolingian Renaissance and to a large extent a continuation of it - this has led historians such as Pierre Riché to prefer evoking it as a 'third Carolingian renaissance', covering the 10th century and running over into the 11th century, with the 'first Carolingian renaissance' occurring during Charlemagne's own reign and the 'second Carolingian renaissance' happening under his successors.
