"great disturbances occurred in the range of the great Caucasus mountain, in the land of the Bulgars, many of whom migrated and came to our lands and settled south of Kokh". Both migrations are dated to the second half of the 4th century AD. The "disturbances" which caused them are believed to be the expansion of the Huns in the East-European steppes. Dimitrov recorded that the toponyms of the Bolha and Vorotan rivers, tributaries of the Aras river, are known as Bolgaru-chaj and Vanand-chaj, and could confirm the Bulgar settlement of Armenia. Around 463 AD, the Akatziroi and other tribes that had been part of the Hunnic union were attacked by the Šarağurs, one of the first Oğuric Turkic tribes that entered the Ponto-Caspian steppes as the result of migrations set off in Inner Asia. According to Priscus, in 463 the representatives of Šarağur, Oğur and Onoğur came to the Emperor in Constantinople, and explained they had been driven out of their homeland by the Sabirs, who had been attacked by the Avars. This tangle of events indicates that the Oğuric tribes are related to the Ting-ling and Tiele people. It seems that Kutrigurs and Unigurs arrived with the initial waves of Oğuric peoples entering the Pontic steppes. The Bulgars were not mentioned in 463. The account by Paul the Deacon in his History of the Lombards (8th century) says that at the beginning of the 5th century in the North-Western slopes of the Carpathians the Vulgares killed the Lombard king Agelmund. Scholars attribute this account to the Huns, Avars or some Bulgar groups were probably carried away by the Huns to the Central Europe. The Lombards, led by their new king Laimicho, rose up and defeated the Bulgars with great slaughter, gaining great booty and confidence as they "became bolder in undertaking the toils of war." The defeated Bulgars then became subjects of the Lombards and later migrated in Italy with their king Alboin. When the army of Ostrogoth chieftain Theodoric Strabo grew to 30,000-men strong, it was felt as a menace to Byzantine Emperor Zeno, who somehow managed to convince the Bulgars to attack the Thracian Goths. The Bulgars were eventually defeated by Strabo in 480/481. In 486 and 488 they fought against the Goths again, first as allies of the Byzantium, according to Magnus Felix Ennodius, and later as allies of the Gepids, according to Paul the
