a celebrated astronomer of Samos, who lived in the 3d century B. C. RALPH. See GORDON, CONNOR, CHARLES WILLIAM. CONRAD I., Duke of Franconia; was elected King of Germany in 911; but Arnulf, Duke of Bavaria, and Henry, Duke of Saxony, disputed his title, and engaged the Huns to overrun Germany. Conrad is said to have received a mortal wound in combat with these revolted chiefs. He died in 918. CONRAD II., son of Henry, Duke of Franconia; was elected King of Germany in 1024. Attempts were made to displace him, but without success, and in 1027 he was crowned emperor at Rome, in the presence of Canute, King of England, and Rudolph, King of Burgundy. As heir to Rudolph, who died in 1033, Conrad became King of Burgundy. He died in 1039. CONRAD III., Duke of Franconia, of the house of Hohenstauffen; born in 1093; was elected emperor in 1138. His title was disputed by Henry the Proud, Duke of Saxony, and the rivalry of these two princes was the germ of the factions afterward so famous under the names of Guelfs and Ghibellines. In 1146, at the diet held at Spire, Conrad was persuaded by the eloquence of St. Bernard to undertake a crusade, on which he set out the following year. It was fruitless and disastrous, and Conrad returned with the wreck of his army in 1149. He died in 1152, CONRAD IV., Duke of Suabia, chosen King of the Romans in 1237, son of the great Emperor Frederick II., and like him was excommunicated by the Pope, Innocent IV., who set up a rival emperor in William, Count of Holland. On the death of his father, in 1250, Conrad marched into Italy to recover the towns which had declared against him. He took Naples, but could not get the investiture of the kingdom of Sicily from the Pope. He died in Italy in 1254. See CONRADIN.
