Abbasi Caliph Mustersid Billah who wanted to
reinforce his position in the political field regulated his relations with Mahmud who was
the sultan of Iraq Seljuks State in a proper order. Furthermore, these two persons had
established an alliance and decided to fight against Sultan Sencer. When Sultan Sencer got
news about this incident, he immediately wrote a letter to Mahmud and wanted him to get
rid of this alliance and his demands was fulfilled. As it can be understood from the
following events, Mahmud seemed to have recognised the political dominion of the caliphate
in Baghdad (1126). This situation obliged Sultan Sencer to make a military expedition in
order to organise his works and affairs in the west. Therefore, he invited Mahmud to the
city of Rey. As a result, he made a negotiation with his nephew in the aforesaid city and
he returned from this meeting in a satisfied manner (1128). After a while, when Mahmud was
to set in motion in order to dismiss the Caliph Mustersid, he died (10th September 1131). Upon the death of Sultan Mahmud, there
was some civil turmoil that aroused in the western section of the Seljuk State. Mahmud's
son, Davud was enthroned to the sultanate of Iraq Seljuks State without the consent of
Sultan Sencer, and his uncle, Mes'ud had opposed to this enthronement. Seljuk-shah was
also involved in the struggles for sultanate between Davud-Mes'ud. Before long, Sultan
Sencer advanced towards the west in order to resolve this complicated situation and he
came to the city of Rey. His nominate for the throne of Irak Seljuks State was his nephew,
Tugrul. Then, Mes'ud, Seljuk-shah and the Caliph Mustersid preferred to collaborate.
Sultan Sencer defeated
the Ruler Mes'ud and his allies in Dinever (26th May 1132) and he enthroned Tugrul to the
reign of the Iraq Seljuks State. However, upon the death of Tugrul within a short period,
Mes'ud became the Sultan of Iraq Seljuks (1134). Sultan Sencer must have understood that
it was no use to intervene in this state for the second time, so he accepted the
enthronement of Mes'ud without his approval. Mes'ud who did not want to yield and submit
to Sultan Sencer had been under the domination of Seljuk emirs. This situation led Sultan
Sencer to organise a military expedition to the west for the last time. He met with Mes'ud
in the city of Rey and he was satisfied with the expressions stated by Mes'ud. Then, he
returned to Khorasan (1150).
