Dandolo. I. Enrico, doge of Venice, member of a patrician Venetian family which traced its origin to the Roman era, born about 1110, died June 1 1205. He served the republic in many capacities, and about 1171 was sent to Constantinople to reclaim the Venetian vessels and subjects unlawfully captured and held by the Byzantines. The emperor Manuel Comne-nus denied the request, and according to some chroniclers nearly blinded him by burning his eyes with hot irons, while more trustworthy accounts attribute his impaired sight to a wound. He was appointed doge in 1192, when he was above 80 years of age, but he still retained all the fire and vigor of youth. During the fourth crusade, the French barons, under Baldwin of Flanders, applied to Venice for aid. At the instance of the doge the necessary sliips were supplied on the promise of a large subsidy, and an alliance was formed with the crusaders. Zara, a city on the Adriatic which had refused to join the league, having been taken and sacked to provide for a de' ficiency in the subsidy, the expedition set sail for Constantinople, on the pretext of enabling young Alexis Angelus to restore his father, who had been deposed by his own brother.

The city was defended by immense fortifications, by deep fosses and strong walls, by massive chains stretched across the harbor, and by 478 towers placed in a circumference of 18 miles. The aged doge, displaying the gonfalon of St. Mark's, animated his followers, the city was taken, the usurping emperor fled, and the rightful monarch was restored (1203). But when he and his young son were treacherously murdered, and the patriarch of Constantinople was driven into exile, the city was again taken and given up to pillage (1204). Dandolo died the following year, and was buried beneath the dome of St. Sophia. - Two other doges of the family preceded Andrea, the last: Giovanni, who reigned from 1279 to 1289, and Feancesco, from 1328 to 1339. II. Andrea, born in 1307, elected doge in 1343, died in 1354. In his first year of office Venice joined in the crusade proclaimed by Pope Clement VI., which ended advantageously to the republic in 1346. Great losses were caused by an earthquake in 1348, and by the defeat of the Venetian Black sea fleet under Pisani by the Genoese under Doria in 1352. In return, Dandolo, in concert with the Byzantine emperor and Aragon, destroyed the Genoese fleet off Cagliari, Aug. 29, 1353. Giovanni Visconti, the new ruler of Genoa, sent Petrarch as ambassador to Venice to negotiate for peace; but, notwithstanding the friendly relations between the poet and the doge, Andrea anew declared war against Genoa in 1354, shortly before his death.

He was succeeded by Marino Faliero. Dandolo was also one of the earliest historians of Venice. He left a Latin chronicle which comprises the history of Venice from the earliest times to 1342, and compiled a portion of* the Venetian laws. A new edition of the Liber Alius, treating of the relations of Venice with Turkey, and of the Liber Blancus, treating of those with the states of Italy (both based upon the chronicles and code of laws left by Dandolo), appeared in Vienna in 1854. III. Girolamo, an Italian author, born in Venice, July 26, 1797, died there, March 26, 1867. He served under the Austrian authorities, and in 1848-9 under Manin, retiring after the restoration of Austrian power, and eventually, during the administration of Maximilian, becoming keeper of archives. Among his various publications are La caduta delta repubblica di Venezia e i suoi ultimi cinquant' anni (Venice, 1858), and Il Carmagnola (1865). He died without issue, the last scion of the illustrious family of his name. His library was purchased for the city of Venice.
