A divan or diwan (, dëvÃÂn; from Sumerian dub, clay tablet) was a high government ministry in various Islamic states, or its chief official (see dewan).
The word, recorded in English since 1586, meaning "Oriental council of a state", comes from Persian (dêvân) and consequently spread via Turkish divan.
It is first attested in Middle Persian spelled as dpywþn and dywþn, itself hearkening back, via Old Persian, Elamite and Akkadian, ultimately to Sumerian dub, clay tablet. The word was borrowed into Armenian as well as divan; on linguistic grounds this is placed after the 3rd century, which helps establish the original Middle Persian (and eventually New Persian) form was dëvÃÂn, not dÃÂvÃÂn, despite later legends that traced the origin of the word to the latter form. The variant pronunciation dÃÂvÃÂn however did exist, and is the form surviving to this day in Tajiki Persian.
In Arabic, the term was first used for the army registers, then generalized to any register, and by metonymy applied to specific government departments. The sense of the word evolved to "custom house" and "council chamber", then to "long, cushioned seat", such as are found along the walls in Middle-Eastern council chambers. The latter is the sense that entered European languages as divan (furniture).
The modern French, Dutch, Spanish, and Italian words douane, aduana, and dogana, respectively (meaning "customs house"), also come from diwan.
The first dëwÃÂn was created under Caliph Umar ( CE) in 15 A.H. (636/7 CE) or, more likely, 20 A.H. (641 CE). It comprised the names of the warriors of Medina who participated in the Muslim conquests and their families, and was intended to facilitate the payment of salary (ÿaá¹ÂÃÂþ, in coin or in rations) to them, according to their service and their relationship to Muhammad. This first army register (dëwÃÂn al-jund) was soon emulated in other provincial capitals like Basra, Kufa and Fustat. Al-Mughira ibn Shu'ba, a statesman from the Thaqif tribe who was versed in Persian, is credited with establishing Basra's dëwÃÂn during his governorship (636âÂÂ638), and the dëwÃÂn of the Caliphate's other garrison centers followed its organization.
With the advent of the Umayyad Caliphate, the number of dëwÃÂns increased. To the dëwÃÂn al-jund, the first Umayyad caliph, Mu'awiya (r. 661âÂÂ680), added the bureau of the land tax (dëwÃÂn al-kharÃÂj) in Damascus, which became the main dëwÃÂn, as well as the bureau of correspondence (dëwÃÂn al-rasÃÂþil), which drafted the caliph's letters and official documents, and the bureau of the seal (dëwÃÂn al-khÃÂtam), which checked and kept copies of all correspondence before sealing and dispatching it. A number of more specialist departments were also established, probably by Mu'awiya: the dëwÃÂn al-barëd in charge of the postal service; the bureau of expenditure (dëwÃÂn al-nafaqÃÂt), which most likely indicates the survival of a Byzantine institution; the dëwÃÂn al-á¹£adaqa was a new foundation with the task of estimating the zakÃÂt and ÿushr levies; the dëwÃÂn al-mustaghallÃÂt administered state property in cities; the dëwÃÂn al-á¹ÂirÃÂz controlled the government workshops that made official banners, costumes and some furniture. Aside from the central government, there was a local branch of the dëwÃÂn al-kharÃÂj, the dëwÃÂn al-jund and the dëwÃÂn al-rasÃÂþil in every province.
Under Caliph Abd al-Malik (), the practices of the various departments began to be standardized and Arabized: instead of the local languages (Greek in Syria, Coptic and Greek in Egypt, Persian in the former Sasanian lands) and the traditional practices of book-keeping, seals and time-keeping, only Arabic and the Islamic calendar were to be used henceforth. The process of Arabization was gradual: in Iraq, the transition was carried out by Salih ibn Abd al-Rahman under the auspices of the governor al-Hajjaj ibn Yusuf in 697, in Syria by Sulayman ibn Sa'd al-Khushani in 700, in Egypt under Caliph al-Walid I's governor Abdallah ibn Abd al-Malik in 706, and in Khurasan by Ishaq ibn Tulayq al-Nahshali on the orders of Yusuf ibn Umar al-Thaqafi, governor of Iraq, in 741/42.
Under the Abbasid Caliphate the administration, partly under the increasing influence of Iranian culture, became more elaborate and complex. As part of this process, the dëwÃÂns increased in number and sophistication, reaching their apogee in the 9thâÂÂ10th centuries. At the same time, the office of vizier (wazër) was also created to coordinate government. The administrative history of the Abbasid dëwÃÂns is complex, since many were short-lived, temporary establishments for specific needs, while at times the sections of larger dëwÃÂn might also be termed dëwÃÂns, and often a single individual was placed in charge of more than one department.
Caliph al-Saffah (r. 749âÂÂ754) established a department for the confiscated properties of the Umayyads after his victory in the Abbasid Revolution. This was probably the antecedent of the later dëwÃÂn al-á¸ÂiyÃÂÿ, administering the caliph's personal domains. Similarly, under al-Mansur (r. 754âÂÂ775) there was a bureau of confiscations (dëwÃÂn al-muá¹£ÃÂdara), as well as a dëwÃÂn al-aḥshÃÂm, probably in charge of palace service personnel, and a bureau of petitions to the Caliph (dëwÃÂn al-riḳÃÂÿ). Caliph al-Mahdi (r. 775âÂÂ785) created a parallel dëwÃÂn al-zimÃÂm (control bureau) for every one of the existing dëwÃÂns, as well as a central control bureau (zimÃÂm al-azimma). These acted as comptrollers as well as coordinators between the various bureaus, or between individual dëwÃÂns and the vizier. In addition, a dëwÃÂn al-maáºÂÃÂlim was created, staffed by judges, to hear complaints against government officials. The remit of the dëwÃÂn al-kharÃÂj now included all land taxes (kharÃÂj, zakÃÂt, and jizya, both in money and in kind), while another department, the dëwÃÂn al-á¹£adaqa, dealt with assessing the zakÃÂt of cattle. The correspondence of the dëwÃÂn al-kharÃÂj was checked by another department, the dëwÃÂn al-khÃÂtam. As in Umayyad times, miniature copies of the dëwÃÂn al-kharÃÂj, the dëwÃÂn al-jund and the dëwÃÂn al-rasÃÂþil existed in every province, but by the mid-9th century each province also maintained a branch of its dëwÃÂn al-kharÃÂj in the capital.
The treasury department (bayt al-mÃÂl or dëwÃÂn al-sÃÂmë) kept the records of revenue and expenditure, both in money and in kind, with specialized dëwÃÂns for each category of the latter (e.g. cereals, cloth, etc.). Its secretary had to mark all orders of payment to make them valid, and it drew up monthly and yearly balance sheets. The dëwÃÂn al-jahbadòha, responsible for the treasury's balance sheets, was eventually branched off from it, while the treasury domains were placed under the dëwÃÂn al-á¸ÂiyÃÂÿ, of which there appear at times to have been several. In addition, a department of confiscated property (dëwÃÂn al-musÃÂdarën) and confiscated estates (dëwÃÂn al-á¸ÂiyÃÂÿ al-maqbà «á¸Âa) existed.
Caliph al-Mu'tadid (r. 892âÂÂ902) grouped the branches of the provincial dëwÃÂns present in the capital into a new department, the dëwÃÂn al-dÃÂr (bureau of the palace) or dëwÃÂn al-dÃÂr al-kabër (great bureau of the palace), where "al-dÃÂr" probably meant the vizier's palace. At the same time, the various zimÃÂm bureaux were combined into a single dëwÃÂn al-zimÃÂm which re-checked all assessments, payments and receipts against its own records and, according to the 11th-century scholar al-Mawardi, was the "guardian of the rights of bayt al-mÃÂl [the treasury] and the people". The dëwÃÂn al-nafaḳÃÂt played a similar role with regards to expenses by the individual dëwÃÂns, but by the end of the 9th century its role was mostly restricted to the finances of the caliphal palace. Under al-Muktafi (r. 902âÂÂ908) the dëwÃÂn al-dÃÂr was broken up into three departments, the bureaux of the eastern provinces (dëwÃÂn al-mashriq), of the western provinces (dëwÃÂn al-maghrib), and of the Iraq (dëwÃÂn al-sawÃÂd), although under al-Muqtadir (r. 908âÂÂ932) the dëwÃÂn al-dÃÂr still existed, with the three territorial departments considered sections of the latter. In 913/4, the vizier Ali ibn Isa established a new department for charitable endowments (dëwÃÂn al-birr), whose revenue went to the upkeep of holy places, the two holy cities of Mecca and Medina, and on volunteers fighting in the holy war against the Byzantine Empire.
Under Caliph al-Mutawakkil (r. 847âÂÂ861), a bureau of servants and pages (dëwÃÂn al-mawÃÂlë wa âÂÂl-ghilmÃÂn), possibly an evolution of the dëwÃÂn al-aḥshÃÂm, existed for the huge number of slaves and other attendants of the palace. In addition, the dëwÃÂn al-khÃÂtam, now also known as the dëwÃÂn al-sirr (bureau of confidential affairs) grew in importance. Miskawayh also mentions the existence of a dëwÃÂn al-ḥaram, which supervised the women's quarters of the palace.
As the Abbasid Caliphate began to fragment in the mid-9th century, its administrative machinery was copied by the emergent successor dynasties, with the already extant local dëwÃÂn branches likely providing the base on which the new administrations were formed.
The administrative machinery of the Tahirid governors of Khurasan is almost unknown, except that their treasury was located in their capital of Nishapur. Ya'qub al-Saffar (r. 867âÂÂ879), the founder of the Saffarid dynasty who supplanted the Tahirids, is known to have had a bureau of the army (dëwÃÂn al-ÿará¸Â) for keeping the lists and supervising the payment of the troops, at his capital Zarang. Under his successor Amr ibn al-Layth (r. 879âÂÂ901) there were two further treasuries, the mÃÂl-e khÃÂṣṣa, and an unnamed bureau under the chief secretary corresponding to a chancery (dëwÃÂn al-rasÃÂþil or dëwÃÂn al-inshÃÂþ).
The Buyids, who took over Baghdad and the remains of the Abbasid Caliphate in 946, drew partly on the established Abbasid practice, but was adapted to suit the nature of the rather decentralized Buyid "confederation" of autonomous emirates. The Buyid bureaucracy was headed by three great departments: the dëwÃÂn al-wazër, charged with finances, the dëwÃÂn al-rasÃÂþil as the state chancery, and the dëwÃÂn al-jaysh for the army. The Buyid regime was a military regime, its ruling caste composed of Turkish and Daylamite troops. As a result, the army department was of particular importance, and its head, the ÿariḠal-jaysh, is frequently mentioned in the sources of the period. Indeed, at the turn of the 11th century, there were two ÿariá¸Âs, one for the Turks and one for the Daylamites, hence the department was often called "department of the two armies" (dëwÃÂn al-jayshayn). A number of junior departments, like the dëwÃÂn al-zimÃÂm, the dëwÃÂn al-á¸ÂiyÃÂÿ, or the dëwÃÂn al-barëd were directly inherited from the Abbasid government. Under Adud al-Dawla (r. 978âÂÂ983), however, the dëwÃÂn al-sawÃÂd, which oversaw the rich lands of lower Iraq, was moved from Baghdad to Shiraz. In addition, a dëwÃÂn al-khilÃÂfa was established to oversee the affairs of the Abbasid caliphs, who continued to reside in Baghdad as puppets of the Buyid emirs.
The Great Seljuks tended to cherish their nomadic origins, with their sultans leading a court to their various capitals. Coupled with their frequent absence on campaign, the vizier assumed an even greater prominence, concentrating the direction of civil, military and religious affairs in his own bureau, the "supreme dëwÃÂn" (dëwÃÂn al-aÿlÃÂ). The dëwÃÂn al-aÿlàwas further subdivided into a chancery (dëwÃÂn al-inshÃÂþ waâÂÂl-á¹ÂughrÃÂ, also called dëwÃÂn al-rasÃÂþil) under the á¹ÂughrÃÂþë or munshë al-mamÃÂlik, an accounting department (dëwÃÂn al-zimÃÂm waâÂÂl-istëfÃÂþ) under the mustawfë al-mamÃÂlik, a fiscal oversight office (dëwÃÂn al-ishrÃÂf or dëwÃÂn al-muÿÃÂmalÃÂt) under the mushrif al-mamÃÂlik, and the army department (dëwÃÂn al-ÿarḠor dëwÃÂn al-jaysh) under the ÿariḠ(further divided into the recruitment and supply bureau, dëwÃÂn al-rawÃÂtib, and the salary and land grants bureau, dëwÃÂn al-iqá¹ÂÃÂþ). A number of lesser departments is also attested, although they may not have existed at the same time: the office charged with the redress of grievances (dëwÃÂn al-maáºÂÃÂlim), the state treasury (bayt al-mÃÂl) and the sultan's private treasury (bayt al-mÃÂl al-khaṣṣ), confiscations (dëwÃÂn al-muá¹£ÃÂdara), the land tax office (dëwÃÂn al-kharÃÂj) and the department of religious endowments or waqfs (dëwÃÂn al-awqÃÂf). A postal department (dëwÃÂn al-barëd) also existed but fell into disuse. The system was apparently partly copied in provincial centres as well.
Following the Ottoman conquest of North Africa, the Maghreb was divided into three provinces, Algiers, Tunis, and Tripoli. After 1565, administrative authority in Tripoli was vested in a Pasha directly appointed by the Sultan in Constantinople. The sultan provided the pasha with a corps of Janissaries, which was in turn divided into a number of companies under the command of a junior officer or Bey. The Janissaries quickly became the dominant force in Ottoman Libya. As a self-governing military guild answerable only to their own laws and protected by a Divan (in this context, a council of senior officers who advised the Pasha), the Janissaries soon reduced the Pasha to a largely ceremonial role.
The Divan-ñ Hümayun or Sublime Porte was for many years the council of ministers of the Ottoman Empire. It consisted of the Grand Vizier, who presided, and the other viziers, the kadi'askers, the nisanci, and the defterdars.
The Assemblies of the Danubian Principalities under Ottoman rule were also called "divan" ("Divanuri" in Romanian) (see Akkerman Convention, ad hoc Divan).
In Malay and related languages, the cognate Dewan is the standard word for chamber, as in the Dewan Perwakilan Rakyat or Chamber of People's Representatives.
In the sultanate of Morocco, several portfolio Ministries had a title based on Diwan:
