between one and the same emperor and one and the same pope. Alexander was that very chancellor Roland who, as Pope Adrian's envoy, had so angered the emperor at Vesançon; he was known, too, to favour Frederick's enemy, William of Sicily.
Alexander was chosen pope by a majority of the cardinals, but his rival, Victor, besides a strong minority, had the people of Rome—whose vote, as they claimed, was still necessary to the election—upon his side; Victor also enjoyed the priority of consecration.
The synod of Pavia (see IV. a) declared for Victor, and Frederick openly ranged himself upon his side. England and France, however, after much vacillation, took the part of Alexander—who, indeed, for years was forced to fight an uphill fight. On Victor's death (1164) his party elected Paschal, and, as the latter' s successor, Calixtus. In 1165 Frederick and a number of his nobles and bishops took a solemn oath at Wurzburg never to acknowledge Roland, or a pope elected by his party.
Alexander found at last, in the Lombard cities and in the king of Sicily, the allies he most needed. After years of stern fighting with the Lombard League fortune turned against the emperor, and he was obliged to flee from Italy to save his life. It was six years before he was able to raise an army and return. He was preparing to strike a final blow for his prestige in Italy when he was deserted by his powerful vassal, Henry the Lion. The battle of Legnano, fought in 1176, proved a great defeat, and paved the way for the peace of Venice (see IV. c). With the Lombards and with the King of Sicily a truce was arranged, and a term fixed within which a lasting peace was to be established. The oath of Wurzburg was broken, and the reconciliation between the heads of Christendom was solemnized at Venice with the greatest possible pomp and display.
