Artabanus V (r. 208–224) summoned all the troops from
Ray,
Damavand, Daylam, and

Vakhtang I of Iberia. This Buya was a native of Daylam, which is proven by the fact that he bore the title ''wahriz'', a Daylamite title also used by

described the Daylamites as;
:"barbarians who live...in the middle of Persia, but have never become subject to the king of the Persians. For their abode is on sheer mountainsides which are altogether inaccessible, and so they have continued to be autonomous from ancient times down to the present day; but they always march with the Persians as mercenaries when they go against their enemies. And they are all foot-soldiers, each man carrying a sword and shield and three javelins in his hand (De Bello Persico 8.14.3-9)."
The equipment of the Dailamites of the Sasanian army included swords, shield, battle-axe (''tabar-zīn''), slings, daggers, pikes, and two-pronged javelins (''zhūpīn'').
Daylamites also took part in the siege of
Archaeopolis in 552. They supported the rebellion of
Bahrām Chōbin against
Khosrow II, but he later employed
an elite detachment of 4000 Daylamites as part of his guard. They also distinguished themselves at the
Yemeni campaign of Wahriz and in the battles against the forces of
Justin II.
Some Muslim sources maintain that following the Sasanian defeat in the
Battle of al-Qādisiyyah, the 4000-strong Daylamite contingent of the Sasanian guard, along with other Iranian units, defected to the Arab side, converting to Islam.
Islamic period
Resistance to the Arabs

The Daylamites managed to resist the Arab invasion of their own mountainous homeland for several centuries under their own local rulers.

penetrated the region and occupied parts of it, but their control was never very effective.
Shortly after 781, the
Nestorian monk
Shubhalishoʿ began evangelizing the Daylamites and converting them to Christianity. He and his associates made only a little headway before encountering competition from Islam. During the reign of
Harun al-Rashid (r. 785–809), several
Shia Muslims fled to the largely pagan Daylamites, with a few Zoroastrians and Christians, to escape persecution. Among these refugees were some

, who began the gradual conversion of the Daylamites to Shia Islam. Nevertheless, a strong Iranian identity remained ingrained in the peoples of the region, along with an anti-Arab mentality. Local rulers such as the
Buyids and the
Ziyarids, made a point of celebrating old Iranian and Zoroastrian festivals.
The Daylamite expansion
From the 9th century onwards, Daylamite foot-soldiers began to comprise an important element of the armies in Iran.
In the mid 9th century, the Abbasid Caliphate increased its need for mercenary soldiers in the
Royal Guard and the army, thus they began recruiting Daylamites, who at the period were not as strong in numbers as the Turks,
Khorasanis, the
Farghanis, and the

during the reign of
al-Muqtadir (r. 908–929). For many decades, "it remained customary for the Caliph's personal guards to include the Daylamites as well as the ubiquitous Turks".
[Bosworth (1975)] The
Buyid ''amīr''s, who were Daylamite themselves, supplemented their army of Daylamite infantrymen with Turkic cavalrymen. Daylamites were among the people comprising the
Seljuq army, and
Ghaznavids also employed them as elite infantry.
[Bosworth (1986)]
Islamic sources record their characteristic painted shields and two-pronged short spears (in ''zhūpīn''; in ''mizrāq'') which could be used either for thrusting or for hurling as a javelin. Their characteristic battle tactic was advancing with a
shield wall and using their spears and battle-axes from behind.
Culture
Religion
The Daylamites were most likely adherents of some form of
Iranian paganism, while a minority of them were
Zoroastrian and
Nestorian Christian. According to
al-Biruni, the Daylamites and Gilites "lived by the rule laid down by the mythical
Afridun." The
Church of the East had spread among them due to the activities of
John of Dailam, and
bishoprics are reported in the remote area as late as the 790s, while it is possible that some remnants survived there until the 14th century.
Names

The name of the king
Muta sounds uncommon, but when in the 9th and 10th centuries Daylamite chieftains appear in the spotlight in massive numbers, their names are undoubtedly pagan Iranian, not of the south-western "Persian" type, but of the north-western type: thus ''Gōrāngēj'' (not ''Kūrānkīj'', as originally interpreted) corresponds to Persian ''gōr-angēz'' "chaser of wild asses", ''Shēr-zil'' to ''Shēr-dil'' "lion’s heart", etc. The medieval Persian geographer
Estakhri differentiates between Persian and Daylami and comments that in the highlands of Daylam there was a tribe that spoke a language different from that of Daylam and Gilan, perhaps a surviving non-Iranian language.
Customs, equipment and appearance
Many habits and customs of the Daylamites have been recorded in historical records. Their men were strikingly tough and capable of lasting terrible privations. They were armed with

s and
battle axes, and had tall shields painted in gray colours. In battle, they would usually form a
wall with their shields against the attackers. Some Daylamites would use javelins with burning
naphtha. A poetic portrayal of Daylamite armed combat is present in
Fakhruddin As'ad Gurgani's ''
Vis and Rāmin''. A major disadvantage of the Daylamites was the low amount of cavalry that they had, which compelled them to work with Turkic mercenaries.
The Daylamites exaggeratedly mourned over their dead, and even over themselves in failure. In 963, the Buyid ruler of

silk textiles. According to
al-Muqaddasi, the Daylamites were handsome and had beards. According to the author of the ''

Rudhrawari, they were "equals of men in strength of mind, force of character, and participation in the management of affairs." Furthermore, the Daylamites also strictly practised
