Daylam in the 10th century Rise (934–945) The founder of the dynasty, '
Ali ibn Buya, was originally a soldier in the service of the Daylamite warlord
Makan ibn Kaki, but later changed his allegiance to the Iranian ruler
Mardavij, who had established the
Ziyarid dynasty, and was himself related to the ruling dynasty of
Gilan, a region bordering Daylam. 'Ali was later joined by his two younger brothers, Hasan ibn Buya and Ahmad ibn Buya. In 932, 'Ali was given
Karaj as his fief, and thus was able to enlist other Daylamites into his army. However, 'Ali's initiative proved too much for Mardavij, who planned to have him killed, but 'Ali was informed of Mardavij's plan by the latter's own
vizier. The brothers, with 400 of their Daylamite supporters, then fled to
Fars, where they managed to take control of
Arrajan. However, the Buyids and the
Abbasid general Yaqut shortly fought for control of Fars, with the Buyids eventually emerging victorious. This victory opened the way for the conquest of the capital of Fars,
Shiraz. 'Ali also allied with the landowners of Fars, which included the
Fasanjas family, which would later produce many prominent statesmen for the Buyids. 'Ali also enlisted more soldiers—including
Turks, who were made part of the cavalry. 'Ali then sent his brother Ahmad on an expedition to
Kerman, but was forced to withdraw after opposition from the
Baloch people and the Qafs. However, Mardavij, who sought to depose the Abbasid caliph of
Baghdad and recreate a Zoroastrian Iranian Empire, shortly wrested
Khuzestan from the Abbasids and forced 'Ali to recognize him as his suzerain. (949-977),
Al-Muhammadiya mint, dated 962-3 Luckily for the Buyids, Mardavij was assassinated shortly thereafter in 935, which caused chaos in the Ziyarid territories, a perfect situation for the Buyid brothers; Ali and Ahmad conquered Khuzistan, while Hasan captured the Ziyarid capital of
Isfahan, and, in 943, captured
Rey, which became his capital, thus conquering all of
Jibal. In 945, Ahmad entered
Iraq and seized control of Baghdad, leaving the Abbasid court with no real option but to submit to their authority as de facto rulers. He received the
laqab ''Mu'izz ad-Dawla'' ("Fortifier of the State"), while 'Ali was given the laqab
Imād al-Dawla ("Support of the State"), and Hasan was given the laqab
Rukn al-Dawla ("Pillar of the State"). The Buyids constructed a royal palace (Dar al-Mamlaka) in Baghdad, situated just north of the caliphal palace (Dar al-Khilafa), symbolizing a division of authority. Meanwhile, the caliph’s influence continued to decline—he no longer had a vizier and effectively became a figurehead under Buyid control.
Height of power and Golden age (945–983) , 966–977 CE, Iran In addition to the other territories the Buyids had conquered, Kerman was conquered in 967, followed by
Oman (967), the
Jazira (979), Tabaristan (980), and
Gorgan (981). After this, however, the Buyids went into a slow decline, with pieces of the confederation gradually breaking off and local dynasties under their rule becoming
de facto independent.
Decline and fall (983–1062) The death of
Adud al-Dawla is considered the start of the decline of the Buyid dynasty; his son
Abu Kalijar Marzuban, who was in Baghdad when he died, at first kept his death secret to ensure his succession and avoid civil war. When he eventually made the death of his father public, he was given the title of "Samsam al-Dawla". However, Adud's other son,
Shirdil Abu'l-Fawaris, challenged his authority, and the feared civil war occurred anyway. Meanwhile, a
Kurdish Marwanid chieftain named
Badh ibn Dustak seized
Diyabakr and forced Samsam al-Dawla to recognize him as the vassal ruler of the region. Furthermore, Mu'ayyad al-Dawla, son of and successor to Rukn al-Dawla, also died during this period. Mu'ayyad al-Dawla was succeeded by his brother Fakhr al-Dawla, who, with the aid of Mu'ayyad al-Dawla's vizier
Sahib ibn 'Abbad, became the ruler of Mu'ayyad al-Dawla's possessions. Another son of Adud al-Dawla,
Abu Tahir Firuzshah, established himself as the ruler of
Basra and took the title of "Diya' al-Dawla", while another son,
Abu'l-Husain Ahmad, established himself as the ruler of Khuzistan, taking the title of "Taj al-Dawla". (r.1024–1048) Shirdil Abu'l-Fawaris (known by his title of "Sharaf al-Dawla") quickly seized Oman from Samsam al-Dawla, and, in 983, the Turkic troops of Samsam al-Dawla mutinied against him and some left Iraq for Fars, but most of them were persuaded by his relative
Ziyar ibn Shahrakawayh to stay in Iraq. However, Iraq was in a grim state, and several rebellions occurred, which he managed to suppress, the most dangerous being that of
Asfar ibn Kurdawayh, who tried to make
Abu Nasr Firuz Kharshadh (known by his title of "Baha' al-Dawla") the ruler of Iraq. During the same period, Samsam al-Dawla also managed to seize Basra and Khuzistan, forcing his two brothers to flee to Fakhr al-Dawla's territory. During the mid-11th century, the Buyid amirates gradually fell to the
Ghaznavids and
Seljuk Turks. In 1029, Majd al-Dawla, who was facing an uprising by his Daylami troops in
Ray, requested assistance from
Mahmud of Ghazna. When Sultan Mahmud arrived, he deposed Majd al-Dawla, replaced him with a
Ghaznavid governor and ended the Buyid dynasty in
Ray. In 1055,
Tughril conquered
Baghdad, the seat of the caliphate, and ousted the last of the Buyid rulers. Like the Buyids, the
Seljuks kept the
Abbasid caliphs as figureheads. == Government ==
