Then the year 519 AH began.

Events of the year:
Dubays and Sultan Tughril marched on Baghdad, intending to wrest it from the Caliph. When they drew near, the Caliph rode out against them at the first staging post with an immense host; the people walked before him, he was dressed in the black Abbasid garb and the cloak, and he held the ceremonial staff ⦗1⦘.

The army then mounted. On the night whose morning was to witness the clash—and they had resolved to plunder Baghdad—Allah sent a torrential rain, and Sultan Tughril fell ill that very night. The forces scattered, turning back in fear and disappointment ⦗2⦘.

Dubays—may Allah disgrace him—and Tughril sought refuge with King Sanjar, asking protection from the Caliph and from Sultan Mahmud. Sanjar imprisoned Dubays in a fortress. An informer then suggested to Sanjar that the Caliph intended to claim sole rule and that he had gone out from Baghdad to al-Lān to fight the enemy ⦗3⦘ ⦗4⦘. The report found a place in Sanjar’s heart and he concealed ill-will ⦗5⦘, although he had given his daughter in marriage to the Caliph.

In this year the judge Abū Saʿd Muḥammad ⦗6⦘ ibn Naṣr ibn Manṣūr ⦗7⦘ al-Harawī was killed in Hamadhān; he was assassinated by the Bāṭinīs ⦗8⦗ ⦗9⦘. The Caliph had sent him to King Sanjar to request the Sultan’s daughter in marriage ⦗10⦘.

The pilgrimage caravan was led by Naẓar al-Khādim.

Among the notable deaths of the year:
Āq Sunqur al-Bursuqī ⦗11⦘, ruler of Aleppo ⦗12⦘.
