Sepahbod

''Spāhbed'' (also spelled ''spahbod'' and ''spahbad'') is a Middle Persian title meaning "army chief" used chiefly in the Sasanian Empire. Originally there was a single ''spāhbed'', called the , who functioned as the generalissimo of the Sasanian army. From the time of Khosrow I ( 531–579) on, the office was split in four, with a ''spāhbed'' for each of the cardinal directions.Gyselen (2004) After the Muslim conquest of Persia, the ''spāhbed'' of the East managed to retain his authority over the inaccessible mountainous region of Tabaristan on the southern shore of the Caspian Sea, where the title, often in its Islamic form ( fa, اسپهبذ; in ar, اصبهبذ ), survived as a regnal title until the Mongol conquests of the 13th century.Bosworth (1978), pp. 207–208 An equivalent title of Persian origin, '' ispahsālār or sipahsālār'', gained great currency across the Muslim world in the 10th–15th centuries.

The title was also adopted by the Armenians ( hy, սպարապետ, ) and the Georgians ( ka, სპასპეტი, ), as well as Khotan () and the Sogdians () in Central Asia. It is also attested in Greek sources as (). The title was revived in the 20th century by the Pahlavi dynasty, in the Modern Persian form (), equivalent to a three-star Lieutenant General, ranking below (full General).

Use in pre-Islamic Iran

The title is attested in the Achaemenid Empire in its Old Persian form, ''spādapati'' (from *''spāda-'' "army" and *''pati-'' "chief"), signifying the army's commander-in-chief. The title continued in use under the Arsacid Parthian Empire, where it seems to have been a hereditary position in one of the seven great houses of the Parthian nobility.

The Sasanian Empire, which succeeded the Arsacids, retained the title, which is attested in a series of inscriptions from the 3rd century, recorded in Middle Persian ( Inscriptional Pahlavi script) as spʾhpty and spʾhpt (read as ''spāhbed'') and in Parthian (Inscriptional Parthian script) as ʾspʾdpty and spdpty (read as ''(a)spāẟbed'').

Until the early 6th century, there was a single holder of the title, the '' Ērān-spāhbed'', who according to the list of precedence provided by the 9th-century Muslim historian Ya'qubi occupied the fifth position in the court hierarchy. Two ''spahbed''s, both named Raxš, are recorded in Shapur-KZ and Paikuli inscriptions.

The Byzantine and Syriac sources record a number of senior officers who might be holders of the rank in the early 6th century. Thus during the Anastasian War of 502–506, a certain Boes (''Bōē''), who negotiated with the Byzantine '' magister officiorum'' Celer and died in 505, is named in the Syriac sources as an ''astabid'' (also spelled ''astabed'', ''astabad'', ''astabadh''). His unnamed successor in the negotiations also bore this title. Some modern scholars have interpreted ''astabed'' as a new office corresponding to the Byzantine ''magister officiorum'', supposedly instituted by Kavadh I shortly before 503 for the purpose of weakening the authority of the '' wuzurg framadar''. But it is likely that this Syriac word is simply a corrupted form of ''spāhbed'' (which is normally recorded as ''aspabid'' in Syriac), or possibly '' asp(a)bed'' ("chief of the cavalry"), since the Greek sources give the name of the second man as ''Aspebedes'' (Latin: '), ''Aspevedes'', or ''Aspetios'' (Latin: ').Chaumont (1987), pp. 825–826 Again, during the Iberian War (526–532), a man named Aspebedes (i.e. Bawi), according to the historian Procopius a maternal uncle of Khosrow I (r. 531–579), appears. In 527 he took part in negotiations with Byzantine envoys, and in 531 he led an invasion of Mesopotamia along with Chanaranges and Mermeroes. He was executed by Khosrow shortly after his accession for plotting with other nobles to overthrow him in favour of his brother Zames.

Khosrow I's reform

To curb the power of the over-mighty generalissimo, Khosrow I—although this reform may already have been planned by his father, Kavadh I (r. 499–531)—split the office of the ''Ērān-spāhbed'' into four regional commands, corresponding to the four traditional cardinal directions (''kust'', cf. '' Šahrestānīhā ī Ērānšahr''): the "army chief of the East (Khurasan)" (''kust ī khwarāsān spāhbed''), the "army chief of the South" (''kust ī nēmrōz spāhbed''), the "army chief of the West" (''kust ī khwarbārān spāhbed''), and the "army chief of Azerbaijan" (''kust ī Ādurbādagān spāhbed'', where the northwestern province of Azerbaijan substitutes the term "north" because of the latter's negative connotations). The exact geographical definition of each command has been retrieved from Anania Shirakatsi's '' Geography''. As this reform was mentioned only in later literary sources, the historicity of this division, or its survival after Khosrow I's reign, was questioned in the past, but a series of thirteen recently discovered seals, which provide the names of eight ''spāhbed''s, provide contemporary evidence from the reigns of Khosrow I and his successor, Hormizd IV (r. 579–590); P. Pourshariati suggests that two may date to the reign of Khosrow II (r. 590–628). The eight known ''spāhbed''s are:

Other holders of the rank are difficult to identify from the literary sources, since the office of ''spāhbed'' was held in tandem with other offices and titles, such as '' Shahrwarāz'' ("Boar of the Empire"), which are often treated as personal names. A further factor of confusion in later literary sources is the interchangeable use of the rank with the junior provincial ranks of ''marzbān'' ("frontier-warden, margrave") and ''pāygōsbān'' ("district guardian").

Islamic period

Tabaristan

During the Muslim conquest of Persia, the ''spahbed'' of Khurasan apparently retired to the mountains of Tabaristan. There he invited the last Sasanian shah, Yazdgerd III, to find refuge, but Yazdgerd refused, and was killed in 651. Like many other local rulers throughout the former Sasanian domains, including those of the neighbouring provinces of Gurgan and Gilan, the ''spahbed'' then made terms with the Arabs, which allowed him to remain as the practically independent ruler of Tabaristan in exchange for an annual tribute. This marked the foundation of the Dabuyid dynasty, which ruled Tabaristan until 759–761, when it was conquered by the Abbasids and incorporated into the Caliphate as a province. The early rulers of the dynasty are ill attested; they minted coins of their own with Pahlavi legends and a dating system starting from the Sasanian dynasty's fall in 651, and claimed the titles ''Gīlgīlan'', ''Padashwargarshah'' ("Shah of Patashwargar", the old name of Tabaristan's mountains), and ''ispahbadh'' (, a New Persian form of ''spahbed'') of Khurasan.

The title ''ispahbadh'' was also claimed by other lines of local rulers in the region, who claimed distant descent from the Sasanian past: the Karen family, who saw themselves as heirs of the Dabuyids and ruled central and western Tabaristan until 839/840, and the Bavandid dynasty in the eastern mountains, whose various branches survived until well after the Mongol conquests of the 13th century.Madelung (1975), pp. 200–202 The title was also used by the Daylamites neighbouring Tabaristan. In some later texts from this region, the title came to signify simply a local chieftain.

Central Asia

In Khurasan, the title survived in usage among the local Soghdian princes. The ''ispahbadh'' of Balkh is mentioned in 709, al-Ishkand, the ''ispahbadh'' of Nasa in 737, and the same title is used in connection with the king of Kabul in the early 9th century. In the 1090s, it appears as the personal name of a Seljuk commander, Isfabadh ibn Sawtigin, who seized control of Mecca for a while.

In Armenia

The Kingdom of Armenia, which was ruled by a branch of the Parthian Arsacid dynasty, adopted the term first in its Old Persian form, giving Armenian '' arapet'' and then again, under Sasanian influence, from the Middle Persian form, giving the form ''aspahapet''. The title was used, as in Persia, for the commander-in-chief of the royal army, and was borne in hereditary right by the Mamikonian family.

In Georgia

The institution of the Georgian rank '' spaspet'', like its rough equivalent ''sparapet'' in neighboring Armenia, was designed under the influence of the Sasanian Persian ''spahbed'', but differed in that it was a non-hereditary rank and included not only military, but also civil functions.Robert Bedrosian, "Sparapet", in: Joseph Reese Strayer (1983), '' Dictionary of the Middle Ages'', p. 460. Scribner, .

According to the medieval Georgian chronicles, the rank of ''spaspet'' was introduced by the first king P’arnavaz in the 3rd century BC.
The office, in a variously modified manner, survived into medieval and early modern Georgia down to the Russian annexation early in the 19th century.
