Luþluþ al-Yaya, also called al-BÃÂbàor al-KhÃÂdim ("the Eunuch"), was the regent of the Seljuk sultanate of Aleppo from <small>AD</small> 1113 (<small>AH</small> 507) until his assassination in 1117 (510). He was the atabeg (father-lord) of the underage sultans. Previously, he had been a eunuch in the service of Aqsunqur al-Bursuqë, the atabeg of Mosul.
According to Ibn al-Athër, Luþluþ took charge of affairs in Aleppo after the death of Sultan Riá¸ÂwÃÂn in 1113, since his son, Alp ArslÃÂn al-Akhras, was only sixteen years old. In 1114, Alp ArslÃÂn was murdered in his own palace by his mamlà «ks at the instigation of Luþluþ because the young sultan had sought the help of Ṭughtakën, ruler of Damascus, to establish his personal rule. Luþluþ then raised Alp ArslÃÂn's six-year-old brother, Sulá¹ÂÃÂn ShÃÂh ibn Riá¸ÂwÃÂn, to the throne and continued to hold the regency. In an effort to solidify his rule, he founded the first khÃÂnaqÃÂh (á¹¢à «fë monastery) in Aleppo, but this generated strong Shia opposition. He was also opposed by the family of SÃÂÿid ibn Badëÿ, raþës (leader) of the aḥdÃÂth (militia), whom Alp ArslÃÂn had exiled to Qalÿat Jaÿbar.
In early 1115, threatened by his fellow Seljuk vassals, Ṭughtakën and êlghÃÂzë of Mardin, Luþluþ requested assistance from the Great Seljuk sultan Muḥammad I Tapar in Baghdad. According to Ibn al-Athër, the sultan sent the Emir Bursuq ibn Bursuq to deal first with the rebels and then with the neighbouring Frankish states. Part of Bursuq's mission was to take charge of Aleppo. When the emir ordered Luþluþ to surrender the city, the regent instead sent for help from his erstwhile enemies, êlghÃÂzë and Ṭughtakën. Reinforcements of 2,000 cavalry entered the city, and Luþluþ went into open defiance of the Great Seljuk sultan. According to Ibn al-ÿAdëm, Luþluþ even passed along intelligence on Bursuq's movements to the Frankish leader Roger of Salerno, who defeated Bursuq at the Battle of Sarmin.
Luþluþ was assassinated in 1117 at the instigation of the family of SÃÂÿid ibn Badëÿ while on his way to meet SÃÂlim ibn MÃÂlik, emir of Qalÿat Jaÿbar. During a rest at a place called Qalÿat NÃÂdir, he was shot with arrows by some of his Turkish retainers who had been pretending to hunt rabbit. Although the assassins plundered the regent's treasure, the people of Aleppo were able to recover it. Luþluþ was succeeded as atabeg by Shams al-KhawÃÂṣṣ YÃÂrà «qtÃÂsh, who had been his military commander. Ibn al-Athër reports the rumour that Luþluþ had intended to kill the young sultan and was assassinated before he could by some friends of Sulá¹ÂÃÂn ShÃÂh. ÃÂmina KhÃÂtà «n took de facto control of the city.
