Ulugh Khan's first siege of Warangal failed because of a rebellion resulting from a false rumour about Ghiyath al-Din's death in Delhi.

The Muslim Khalji rulers of Delhi Sultanate had invaded the Kakatiya capital Warangal twice, in 1310 and 1318, forcing Prataparudra to become their tributary.

[2] Amid the political instability resulting from the end of the Khalji dynasty in 1320, Prataparudra stopped sending tributes to Delhi.

[3] Ulugh Khan's first siege was unsuccessful: the Muslim chroniclers blame a man named Ubaid for this failure, although their accounts vary about the exact cause.

When Ghiyath al-Din expressed his displeasure at the siege operations in letters from Delhi, Ulugh Khan consulted his astrologer Ubaid.

He also told the soldiers that Ulugh Khan had decided to kill the chief amirs of the Delhi army in Warangal, because he suspected them of being Khalji sympathisers.

[6] According to the Delhi chronicler Ziauddin Barani, at one point, Ulugh Khan was on the verge of winning, and Prataparudra offered to negotiate a truce.

[7] According to the Moroccan traveler Ibn Battuta, it was Ulugh Khan who asked Ubaid to spread the false rumour, because he wanted to seize the throne of Delhi from his father.

The veracity of Ibn Battuta's account is doubtful, because it contradicts the Indian chronicles, and because he wrote it from memory several years later, after returning to Morocco.

Within four months of his retreat, Ulugh Khan marched to Telangana again, this time capturing enemy forts en route to Warangal.
