In 1334 there was a rebellion in Mabar. While on his way to suppress the rebellion, there was an outbreak of bubonic plague at Bidar due to which Tughluq himself became ill, and many of his soldiers died. While he retreated back to Daulatabad, Mabar and Dwarsamudra broke away from Tughluq's control. This was followed by a revolt in Bengal. Fearing that the sultanate's northern borders were exposed to attacks, in 1335, he decided to shift the capital back to Delhi, allowing the citizens to return to their previous city.
