Arab poets, including Ibn Hamdis, the most important Sicilian Arab poet of the 12th century, flourished in the city. Norman kingdom of Sicily In 1038, the Byzantine general George Maniakes reconquered the city, sending the relics of St. Lucy to Constantinople. The eponymous castle on the cape of Ortygia bears his name, although it was built under the Hohenstaufen rule. In 1085 the Normans entered Syracuse, one of the last Arab strongholds, after a summer-long siege by Roger I of Sicily and his son Jordan of Hauteville, who was given the city as count. New quarters were built, and the cathedral was restored, as well as other churches. High medieval period In 1194, Emperor Henry VI occupied the Sicilian kingdom, including Syracuse. After a short period of Genoese rule (1205–1220) under the notorious admiral and pirate Alamanno da Costa, which favoured a rise of trades, royal authority was re-asserted in the city by Frederick II. He began the construction of the Castello Maniace, the Bishops' Palace and the Bellomo Palace. Frederick's death brought a period of unrest and feudal anarchy. In the War of the Sicilian Vespers between the Angevin and Aragonese dynasties for control of Sicily, Syracuse sided with the Aragonese and expelled the Angevins in 1298, receiving from the Spanish sovereigns great privileges in reward. The preeminence of baronial families is also shown by the construction of the palaces of Abela, Chiaramonte, Nava, Montalto. 16th–20th centuries The city was struck by two ruinous earthquakes in 1542 and 1693, and a plague in 1729. The 17th century destruction changed the appearance of Syracuse forever, as well as the entire Val di Noto, whose cities were rebuilt along the typical lines of Sicilian Baroque, considered one of the most typical expressions of the architecture of Southern Italy. The spread of cholera in 1837 led to a revolt against the Bourbon government. The punishment was the move of the province capital seat to Noto, but the unrest had not been totally choked, as the Siracusani took part in the Sicilian revolution of 1848. After the Unification of Italy of 1865, Syracuse regained its status of provincial capital. In the late 19th century, the walls (including Porta Ligny) were demolished and a bridge connecting the mainland to Ortygia island was built. In the following year a railway link was constructed.
