The Bulgarians (Italian: Bulgari) in Italy (Bulgarian: Италия, Italiya) are one of the sizable communities of the Bulgarian diaspora in Western Europe. There are about 120,000 Bulgarians in Italy according to the Bulgarian government. There are Bulgarian Orthodox parishes in Rome and Milan. Major centres of Bulgarian migration are Milan, Bologna, Florence and Torino.
In the early 7th century AD, groups of Bulgars, one of the ancient peoples that participated in the ethnogenesis of the modern Bulgarians, settled in the Italian Peninsula. The main migration was headed by Altsek, a Bulgar leader who initially joined the Avar Khaganate before switching allegiance to the Germanic Lombards. Altsek and his people arrived in the Exarchate of Ravenna, where Grimoald I of Benevento invited them to populate the Duchy of Benevento. According to the Gesta Dagoberti I regis Francorum, Altsek's Bulgars settled in what are today the communes of Isernia, Bojano and Sepino. Altsek remained the leader of the Bulgar-populated areas, bearing the title gastald.
It is uncertain whether this Altsek can be identified with another Bulgar lord, Altsiok. According to the Chronicle of Fredegar, Altsiok deserted the Avar Khaganate in 631–632. Altsiok settled in Bavaria with 9,000 Bulgars under Frankish king Dagobert I. Altsiok is known to have moved to the Venetian March with his 700 remaining men after Dagobert I slaughtered most of his people.
