(1324), then ruled by the
Karnats of Mithila. A 1410 Jalayrid Mongol illustration of the
Basātin al-uns, a book written by
Akhsatan Dehlavi al-Hindi, a member of the Tughluq court and an ambassador to Iran. Ca.1410 copy of 1326 lost original. Istanbul, Topkapi Palace Museum Library, Ms. R.1032. In July 1320, Mubarak Shah was murdered as a result of a conspiracy by his general
Khusrau Khan, who became the ruler of Delhi. Tughluq was one of the governors who refused to recognize Khusrau Khan as the new Sultan. However, he did not take any action against Khusrau Khan because the force commanded by him at Dipalpur was not strong enough to take on the imperial army at Delhi. Tughluq's son
Fakhruddin Jauna (who later ascended the throne as Muhammad bin Tughluq), who was a high-ranking officer in Delhi, took the initiative to dethrone Khusrau Khan. He convened a secret meeting of his friends in Delhi, and then sent his messenger Ali Yaghdi to Dipalpur, asking his father for assistance in the matter. In response, Tughluq asked him to come to Dipalpur with the son of the
Uchch governor Bahram Aiba, who was also opposed to Khusrau Khan. Accordingly, Fakhruddin and his companions - which included some slaves and servants - left Delhi for Dipalpur on horses one afternoon. Tughluq sent his officer Muhammad Sartiah to take control of the
Sirsa fort on the Delhi-Dipalpur route to secure a safe passageway for his son. When Khusrau Khan learned of the conspiracy, he dispatched his minister of war Shaista Khan in pursuit of Fakhruddin, but Shaista Khan could not catch the rebels. At Dipalpur, Tughluq and his son discussed the situation, and decided to put up a fight against Khusrau Khan. Tughluq declared that he wanted to dethrone Khusrau Khan for "the glory of Islam", because he was loyal to Alauddin's family, and because he wanted to punish the criminals in Delhi. At Dipalpur, Tughluq and his son discussed the situation, and decided to put up a fight against Khusrau Khan. Tughluq sent identical letters to five neighbouring governors, seeking their support: • Bahram, the governor of Uchch, joined Tughluq's cause and provided military support. • Mughlati, the governor of Multan, refused to rebel against the new Sultan. Tughluq's friend Bahram Siraj incited Mughlati's army against him. Facing a rebellion himself, Mughlati tried to flee but fell into a canal built during Tughluq's governorship of Multan. He was beheaded by a son of Bahram Siraj, but the Multan army did not join Tughluq's forces against the Sultan. • Malik Yak Lakkhi, the governor of
Samana, not only refused to join Tughluq, but also sent his letter to Khusrau Khan and himself marched to Dipalpur against him. Yak Lakkhi was originally a Hindu slave, and may have been favoured by Khusrau Khan, which may explain his actions. After Tughluq's forces repelled his invasion of Dipalpur, he retreated to Samana. He was planning to join the Sultan at Delhi, but was killed by the angry citizens before he could do that. • Muhammad Shah Lur, the governor of
Sindh, was facing a rebellion by his officers when he received Tughluq's letter. He later came to terms with his officers, and agreed to support Tughluq, but reached Delhi only after Tughluq ascended the throne. Tughluq later appointed him as the governor of
Ajmer. • Hushang Shah, the governor of
Jalor and a son of
Kamal al-Din Gurg, also promised to support Tughluq. However, he deliberately reached Delhi only after the battle between the forces of Tughluq and Khusrau Khan was over. Tughluq retained him as the governor of Jalor. Tughluq sent another letter to
Ayn al-Mulk Multani, who had become the
wazir by this time. Multani was surrounded by Khusrau Khan's men when he received the letter, so he took the letter to the Sultan and expressed his loyalty. However, when Tughluq sent a second message to him, he expressed sympathy with Tughluq's cause. Multani stated that he was surrounded by Khusrau's allies, and therefore, would not take sides in the upcoming battle. He told Tughluq that he would withdraw on the approach of Tughluq's forces to Delhi, and that Tughluq could choose to retain him or kill him upon becoming the Sultan.

Ghuzz,
Turks and
Mongols of Rum and Rus and some Khurasani Persians. However, with the exception of a Mongol officer, Khusrau does not mention any soldiers from these ethnicities. According to historian
Banarsi Prasad Saksena, Khusrau's enumeration of these ethnicities is "an official disguise" for the Hindu communities that fought for Tughluq, who claimed to be fighting for the "glory of Islam". The
Khokhars were one of these communities: their ruler was Sahij Rai, and their chiefs included Gul Chandra and Niju. The
Mewatis, also known as Meos, were another community of Hindu origin that supported Tughluq. Tughluq's officers captured a
caravan carrying tribute from
Sindh to Delhi, along with a number of horses. Tughluq distributed the seized treasure among his soldiers. Meanwhile, in Delhi, to discourage any further conspiracies, Khusrau Khan consulted his counsellors, and ordered killings of Alauddin's three sons - Bahauddin, Ali, and Usman - who had earlier been blinded and imprisoned. Tughluq's army defeated Khusrau Khan's forces at the
Battle of Saraswati and the
Battle of Lahrawat. Khusrau Khan fled from the battlefield, but was captured and killed a few days later. Tughluq was proclaimed the new ruler on 6 September 1320. ==Reign==
