Abu Ishaq Ibrahim
Abu Ishaq Ibrahim, also known by his honorific title of Umdat al-Dawla ("Mainstay of the Empire"), was a Buyid prince, who was the youngest son of the Buyid ruler Mu'izz al-Dawla.
Mu'izz al-Dawla
Ahmad ibn Buya (Persian: احمد بن بویه, died April 8, 967), after 945 better known by his "laqab" of Mu'izz al-Dawla ("Fortifier of the Dynasty"), was the first of the Buyid emirs of Iraq, ruling from 945 until his death.
The son of Daylamite fisherman who had converted to Islam,
Ahmad ibn Buya was born in the mountainous region of Daylam, and by 928, he along with his two brothers served the Daylamite military leader Makan ibn Kaki.
However, they quickly changed their allegiance to the Ziyarid ruler Mardavij, but some years later rebelled against him after founding out that he planned to murder one of the brothers.
In 935/6, Ahmad ibn Buya unsuccessfully invaded Kerman, and was later sent to Istakhr.
From there he started making incursions into Khuzestan and later Iraq; by 945, he was officially recognized as the ruler of Iraq and Khuzestan and had received the title of "Mu'izz al-Dawla" from the Caliph, while his two other brother were the rulers of other territories and had also received titles from the Caliph.
Throughout his rule, Mu'izz al-Dawla was devoted in conflicts with other dynasties for control over Iraq—in 946, an important battle took place in Baghdad between Mu'izz al-Dawla and the Hamdanid amir Nasir al-Dawla, which lasted several months, with Mu'izz al-Dawla ending as the victor. Mu'izz
al-Dawla also fought against the Batihah amirate several times, but was unable to decisively defeat it. Mu'izz
al-Dawla also had problems with some of his Daylamite kinsmen, who would sometimes rebel against him, the most dangerous rebellion being under Ruzbahan from 955 to 957.
By Mu'izz al-Dawla's death in 967, he had defeated all his foes and was the unchallenged ruler of Iraq.
He was succeeded by his son Izz al-Dawla.
Abu Bakr Lawik
Abu Bakr Lawik was a ruler of Ghazna( in modern Afghanistan) from the Lawik dynasty.
He was most likely a vassal of the Samanid Empire.
In 962, the Turkic slave commander Alp- Tegin seized Ghazna from him.
However, a few years he later managed to re-capture the town from Abu Ishaq Ibrahim, the son and successor of Alp- Tegin.
This was not to last long; Abu Ishaq Ibrahim shortly returned to the town with Samanid aid, and took control of the town once again.
Abu Bakr Lawik is thereafter no longer mentioned; he died before 977, the year that Ghaznavid control was established in Ghazna.

He immediately set about trying to reduce the autonomy of the Kutama Berbers in order to stop the Ismailite mission of Abu' Abdullah al- Shi'i, however without success.
