Diwan Al-barid

The ''barīd'' ( ar, بريد, often translated as "the postal service") was the state-run courier service of the Umayyad and later Abbasid Caliphates. A major institution in the early Islamic states, the ''barid'' was not only responsible for the overland delivery of official correspondence throughout the empire, but it additionally functioned as a domestic intelligence agency, which informed the caliphs on events in the provinces and the activities of government officials.

Etymology

The etymology of the Arabic word ''barid'' has been described by historian Richard N. Frye as "unclear". A Babylonian origin has been suggested by late-19th-century scholars who offered the following disputed explanation: ''berīd'' = Babyl. ''buridu'' (for the older *''(p)burādu'') = 'courier' and 'fast horse'. It has also been proposed that, since the ''barid'' institution appears to have been adopted from the courier systems previously maintained by both the Byzantines and Persian Sassanids, the word ''barid'' could be derived from the Late Latin ''veredus'' ("post horse") or the Persian ''buridah dum'' ("having a docked tail," in reference to the postal mounts).

History

Background

The Muslim ''barid'' was apparently based upon the courier organizations of their predecessors, the Byzantines and Sassanids. Postal systems had been present in the Middle East throughout Antiquity, with several pre-Islamic states having operated their own services. A local tradition of obliging the population living next to roads to carry the luggage of passing soldiers and officials, or of having the entire population contribute pack animals to the state as in Ptolemaic Egypt, has been documented since at least the time of the Achaemenid Empire and had been enforced by Roman legislation in the 4th century.

Umayyads

The ''barid'' operated from Umayyad times, with credit for its development being given to the first Umayyad caliph Mu'awiyah ibn Abi Sufyan (r. 661–680). Mu'awiyah's successor Abd al-Malik ibn Marwan (r. 685–705) strengthened the organization, making additional improvements to it after the end of the Second Fitna. The Umayyads created a ''diwan'' or government department to manage the system and a separate budget was allocated for its costs.

Abbasids

Following the Abbasid Revolution in 750, the ''barid'' was further strengthened by the new dynasty and became one of the most important institutions in the government. The second Abbasid caliph al-Mansur (r. 754–775) placed particular importance on the service and utilized it as an intelligence tool with which he could monitor affairs throughout the empire. Under his successors, oversight of the ''barid'' was often entrusted to a prominent official or close associate of the caliph, such as the Barmakid Ja'far ibn Yahya or Itakh al-Turki.

9th–11th centuries

After the political fragmentation of the Abbasid Caliphate in the ninth and tenth centuries, the central ''diwan al-barid'' was overseen by the Buyids (945–1055), but the organization seems to have declined during this period. The service was eventually abolished by the Seljuq sultan Alp Arslan (r. 1063–1072), who considered its capacity for intelligence-gathering to have been diminished. Some other Muslim states, such as the Samanids of Transoxiana (9th and 10th centuries), maintained their own ''barid'' systems at various times.

Mamluks

In the thirteenth century a new ''barid'' was created in Egypt and the Levant by the Mamluk sultan Baybars (r. 1260–1277).

Functions

Correspondence and travel

The ''barid'' provided the caliphs with the ability to communicate with their officials in the various regions under their authority. Its messengers were capable of delivering missives throughout the empire with great efficiency, with reported travel speeds as fast as almost a hundred miles per day. The ''barid'' was not a mail service, and did not normally carry private letters sent by individuals; rather it usually only carried correspondence, such as official reports and decrees, between government agents.

To facilitate the swift delivery of its messages, the ''barid'' maintained an extensive network of relay stations, which housed fresh mounts, lodging and other resources for its couriers. The average distance between each ''barid'' station was, at least in theory, two to four ''farsakh''s (six to twelve miles); according to the 9th-century geographer Ibn Khurradadhbih, there were a total of 930 stations throughout the empire. This relay network was flexible and temporary postal stations could be set up as needed; during military campaigns, for example, new ''barid'' stations would be established so that a line of communication could be maintained with the advancing army.

Besides carrying correspondence, the ''barid'' was sometimes used to transport certain agents of the state, providing a form of fast travel for governors and other officials posted to the provinces. The Abbasid caliph al-Hadi (r. 785–786), for example, used the ''barid'' service to make the journey from Jurjan to the capital Baghdad after he had received news of his father's death. Use of ''barid'' resources was tightly controlled, however, and special authorization was required for other government agents to use their mounts or provisions.

Surveillance

In addition to its role in as a courier service, the ''barid'' operated as an intelligence network within the Islamic state. The postmasters ('' ashab al-barid'') of each district effectively doubled as informants for the central government, and regularly submitted reports to the capital of the state of their respective localities. Any events of significance, such as local trial proceedings, fluctuations in prices of essential commodities, or even unusual weather activity, would be written about and sent to the director of the central ''diwan'', who would summarize the information and present it to the caliph.

Besides the affairs of the provinces in general, ''barid'' agents also monitored the conduct of other government officials. Postmasters were to look out for any instances of misconduct or incompetence and inform the caliph of any such behavior. They also reported on the acts and decrees of the local governor and judge, as well as the balance of the treasury. This information enabled the caliph to stay apprised of the performance of his agents, and to dismiss any who had become corrupt or rebellious.
