Foundation of the Duchy of Friuli The Lombards penetrated into Italy without meeting any resistance from the border troops (
milities limitanei). The Byzantine military resources available on the spot were scant and of dubious loyalty, and the border forts may well have been left unmanned. What seems certain is that archaeological excavations have found no sign of violent confrontation in the sites that have been excavated. This agrees with Paul the Deacon's narrative, who speaks of a Lombard takeover in
Friuli "without any hindrance". The first town to fall into the Lombards' hands was
Forum Iulii (Cividale del Friuli), the seat of the local
magister militum. Alboin's decision to create a duchy and designate a duke were both important innovations; until then, the Lombards had never had dukes or duchies based on a walled town. The innovation adopted was part of Alboin's borrowing of Roman and Ostrogothic administrative models, as in Late Antiquity the
comes civitatis (city count) was the main local authority, with full administrative powers in his region. But the shift from count (
comes) to duke (
dux) and from county (
comitatus) to duchy (
ducatus) also signalled the progressive militarization of Italy.
Conquest of Milan From Forum Iulii, Alboin next reached
Aquileia, the most important road junction in the northeast, and the administrative capital of Venetia. The imminent arrival of the Lombards had a considerable impact on the city's population; the
Patriarch of Aquileia Paulinus fled with his clergy and flock to the island of
Grado in Byzantine-controlled territory. From Aquileia, Alboin took the
Via Postumia and swept through Venetia, taking in rapid succession
Tarvisium (Treviso),
Vicentia (Vicenza),
Verona,
Brixia (
Brescia) and
Bergomum (Bergamo). The Lombards faced difficulties only in taking
Opitergium (Oderzo), which Alboin decided to avoid, as he similarly avoided tackling the main Venetian towns closer to the coast on the
Via Annia, such as
Altinum,
Patavium (Padova),
Mons Silicis (Monselice),
Mantua and
Cremona. Alboin moved west in his march, invading the region of
Liguria (north-west Italy) and reaching its capital
Mediolanum (
Milan) on 3 September 569, only to find it already abandoned by the
vicarius Italiae (vicar of Italy), the authority entrusted with the administration of the
diocese of Annonarian Italy. Archbishop
Honoratus, his clergy, and part of the laity accompanied the
vicarius Italiae to find a safe haven in the Byzantine port of
Genua (Genoa). Alboin counted the years of his reign from the capture of Milan when he assumed the title of
dominus Italiae (Lord of Italy). His success also meant the collapse of Byzantine defences in the northern part of the
Po plain, and large movements of refugees to Byzantine areas. Several explanations have been advanced to explain the swiftness and ease of the initial Lombard advance in northern Italy. It has been suggested that the towns' doors may have been opened by the betrayal of the Gothic auxiliaries in the Byzantine army, but historians generally hold that Lombard's success occurred because Italy was not considered by Byzantium as a vital part of the empire, especially at a time when the empire was imperilled by the attacks of Avars and
Slavs in the
Balkans and
Sassanids in the east. The Byzantine decision not to contest the Lombard invasion reflects the desire of Justinian's successors to reorient the core of the Empire's policies eastward.
Impact of the migration on Annonarian Italy The impact of the Lombard migration on the Late Roman aristocracy was disruptive, especially in combination with the Gothic War; the latter conflict had finished in the north only in 562, when the last Gothic stronghold, Verona, was taken. Many men of means (Paul's
possessores) either lost their lives or their goods, but the exact extent of the despoliation of the Roman aristocracy is a subject of heated debate. The clergy was also greatly affected. The Lombards were mostly pagans and displayed little respect for the clergy and Church property. Many churchmen left their
sees to escape from the Lombards, like the two most senior bishops in the north, Honoratus and Paulinus. However, most of the
suffragan bishops in the north sought an accommodation with the Lombards, as did in 569 the bishop of Tarvisium, Felix, when he journeyed to the
Piave river to parley with Alboin, obtaining respect for the Church and its goods in return for this act of homage. It seems certain that many sees maintained an uninterrupted episcopal succession through the turmoil of the invasion and the following years. The transition was eased by the hostility existing among the northern Italian bishops towards the papacy and the empire due to the religious dispute involving the "
Three-Chapter Controversy". In Lombard territory, churchmen were at least sure to avoid imperial religious persecution. In the view of Pierre Riché, the disappearance of 220 bishops' seats indicates that the Lombard migration was a crippling catastrophe for the Church. Yet according to Walter Pohl the regions directly occupied by Alboin suffered less devastation and had a relatively robust survival rate for towns, whereas the occupation of territory by autonomous military bands interested mainly in raiding and looting had a more severe impact, with the bishoprics in such places rarely surviving.
Siege of Ticinum The first attested instance of strong resistance to Alboin's migration took place at the town of
Ticinum (
Pavia), which he started to besiege in 569 and captured only after three years. The town was of strategic importance, sitting at the confluence of the rivers
Po and
Ticino and connected by waterways to Ravenna, the capital of Byzantine Italy and the seat of the
Praetorian prefecture of Italy. Its fall cut direct communications between the garrisons stationed on the
Alpes Maritimae and the
Adriatic coast. Careful to maintain the initiative against the Byzantines, by 570 Alboin had taken their last defences in northern Italy except for the coastal areas of Liguria and Venetia and a few isolated inland centres such as
Augusta Praetoria (Aosta),
Segusio (Susa), and the island of
Amacina in the
Larius Lucus (Lake Como). During Alboin's kingship the Lombards crossed the
Apennines and plundered
Tuscia, but historians are not in full agreement as to whether this took place under his guidance and if this constituted anything more than raiding. According to
Herwig Wolfram, it was probably only in 578–579 that
Tuscany was conquered, but Jörg Jarnut and others believe this began in some form under Alboin, although it was not completed by the time of his death. The king's disintegrating authority over his army was also manifested in the invasion of Frankish
Burgundy which from 569 or 570 was subject to yearly raids on a major scale. The Lombard attacks were ultimately repelled following
Mummolus' victory at
Embrun. These attacks had lasting political consequences, souring the previously cordial Lombard-Frankish relations and opening the door to an alliance between the Empire and the Franks against the Lombards, a coalition agreed to by
Guntram in about 571. Alboin is generally thought not to have been behind this invasion, but an alternative interpretation of the transalpine raids presented by Gian Piero Bognetti is that Alboin may actually have been involved in the offensive on Guntram as part of an alliance with the Frankish king of
Austrasia,
Sigebert I. This view is met with scepticism by scholars such as
Chris Wickham. The weakening of royal authority may also have resulted in the conquest of much of southern Italy by the Lombards, in which modern scholars believe Alboin played no role at all, probably taking place in 570 or 571 under the auspices of individual warlords. However it is far from certain that the Lombard takeover occurred during those years, as very little is known of
Faroald and
Zotto's respective rises to power in
Spoletium (
Spoleto) and
Beneventum (
Benevento). == Assassination ==
