About 530, when Narses the Eunuch began the great campaign which wrested the Italian dominions of the Emperors from the Goths, the Venetians gave him effective aid by transporting an army of Lombard mercenaries from Aquileia to Ravenna. As a reward Narses sent some Byzantine masters, who from the spoils of the enemy built the Church of St Theodore at Rivoalto on a plot of ground known as the Broglio or garden where now stands the Basilica of St Mark.
Scarcely, however, were the Goths defeated, when in 568 Alboin and his Lombards menaced the land. Longinus, who succeeded Narses in the exarchate of Ravenna, came to Venice and asked her aid as subject to the Emperor. He was given an honourable and festive welcome, but the Venetians had bought their freedom at a great price and stoutly refused to admit his claim. They declared that the second Venice which they had made in the waters was a mighty habitation and their very own by right of creation; that they feared no power of Prince or Emperor, for it could not reach them. They, however, furnished a ship and sent an embassy with Longinus to Constantinople, and in return for valuable trading rights, agreed to acknowledge the suzerainty of the Emperor if no formal oath were exacted.
In 584 the lagoon folk had so expanded that an additional tribune was chosen for each community. Of these Tribuni majores was formed a federal council, the original tribunes now serving as heads of local administrations.
The golden age so lovingly dwelt upon by the early chroniclers was of short duration. Already, before the institution of the new tribunes, family and local feuds, the ambition of the tribunes and jealousy of the people, led to bloody affrays in the Pinete (pine forests) with which the lidi were clothed. Anarchy threatened the state; bands of Lombards under the Duke of Friuli plundered the churches of Heraclea and Grado. The crisis was met by the public spirit and wisdom of the Church. A general meeting (Arengo) was called by the Patriarch of Grado at Heraclea. Two vital problems came to the front—the organisation of self-defence and the maintenance of public order. The whole Assembly having invoked the name of Christ, the great churchman stood forth, and after reviewing the political situation, proposed that all the tribunes should be relegated to purely local offices, and a Capo or chief elected for life. His new polity was approved and in 697 Pauluccio Anafesto was chosen first Doge and invested with sovereign powers. Thus was constituted the Dogeship of Venice which, save for a short interruption of six years, endured for eleven centuries. The Doge could nominate, degrade or dismiss all public officers, convoke or dissolve the Arengo and the synod. The appointment of Patriarchs and Bishops was subject to his veto. The military authority, entrusted to a Master of the soldiers, was subordinate to him; foreign affairs were in his hands, though the approval of the people was required to declare war or conclude peace. He could impose taxes; his feudal dues and rights of corvée were extensive. His state was regal. When he went abroad, girt with a sword and surrounded by his guards, a state umbrella was held over him, lighted tapers were borne by his side, trumpets blared and banners waved. He sat enthroned in an ivory chair, holding a sceptre, and arrayed in a silk mantle with a fringe of gold fastened by a gold clasp over a tightly fitting tunic trimmed with ermine; he wore red hose and a high biretta richly jewelled, which was subsequently shortened by constricting the middle so as to form two lobes, one of which soon disappeared, and the familiar horned cap of the later Doges was evolved. A close cap of fine linen was worn beneath, so that when the biretta was raised his head should be covered as a mark of dignity. The Doge was no fainéant. He rose before the dawn, and having heard mass went forth to judge the people and transact the business of the day. On solemn occasions he gave his benediction. The blessing of God was invoked upon him in the litany. The election, more or less democratic until the abolition of the Arengo in 1423, was made by the whole people, who were summoned from Grado to Cavarzere. Their chosen one was acclaimed and carried shoulder high to the church, which he entered barefoot, and there swore to govern according to the laws and to work for the good of the people. The result of the election was communicated to the Pope and the Emperor; to the latter usually by the Doge’s son in person.
Anafesto had a difficult task. The young state lay between two mighty powers: Lombards or Franks and Pope in the west, the Byzantine Emperor in the east. Only by vigilance and prudence could she escape subjection. And these rival interests were active within her borders—aristocratic Heraclea leaning towards the Eastern Empire; democratic Malamocco and Jesolo towards the Western kingdoms and the Pope. One of the first acts of the new Doge, after securing internal peace, was to conclude a treaty with Luitprand, King of the Lombards, by which the boundaries of the Republic were defined, and in return for an annual payment, valuable rights of wood-cutting and horse-breeding and trading were conceded. But political jealousy dies hard. Two powerful families revolted in 717, and the Doge perished in a civil broil in the Pineta of Jesolo.
During the reign of the third Doge, Orso of Heraclea, the Venetians were called to meet a new danger. The rise of the Iconoclasts in the early eighth century, and the zeal of their protagonist, the Emperor Leo III., had set east and west aflame. Leo’s attempt to enforce the decree against the use of images in the western Church was met by an invitation to the Lombards from the Pope to attack the seat of the eastern power in Italy. War was the very breath of their nostrils, and they were not slow to respond. Ravenna was besieged and captured and the Pentapolis occupied.[2] The Exarch Paul fled to the lagoons and appealed to Orso for help. The fugitive enlarged on the danger to Venice of the advancing Lombards, now at their very door. The Doge agreed to furnish a fleet, and by successful strategy Ravenna was surprised and recaptured and the Exarchate restored. The gratified Emperor rewarded the Venetians by conferring the title of Hypatos (knight) on their Doge, who adopted it as a family name.
This imperial policy was, however, bitterly resented by the popular party. A civil war ensued which lasted two years, and ended in the defeat of the Heracleans, the murder of the Doge, and the banishment of his son. Another experiment in statecraft was now made. The Dogeship was abolished, and the Master of the soldiers appointed head of the State for a term of one year. This new departure proved disastrous. After six years of civil discord, the last of the Masters, a Heraclean, was captured and blinded by the opposite party. An Arengo was called, this time at Malamocco, and a compromise effected. Deodato, son of Orso, a Heraclean, was made Doge at Malamocco, whither the capital was now transferred. But Heraclea and Jesolo were rivals, fierce as ever, for the ducal chair. The internecine strife went on with its savage incidents. Assassination, blinding,[3] or banishment were the price of defeat. At length, by the election of Maurizio Galbaio in 764, “noble by race, nobler in deeds,” the distracted state was ruled with wisdom and firmness, and faction for a time was silenced.
