who was the sultan of delhi when timir invaded
Timur In 1398, Timur invaded northern India, attacking the Delhi Sultanate ruled by Sultan Nasir-ud-Din Mahmud Shah Tughluq of the Tughlaq Dynasty. He was opposed by Ahirs and faced some reversals from the Jats, but the Sultanate at Delhi did nothing to stop him.[59][60] After crossing the Indus river on 30 September 1398, he sacked Tulamba and massacred its inhabitants.[61] Then he advanced and captured Multan by October.[62]
Mamluk dynasty (Delhi) The third Sultan was Shams-ud-din Iltutmish (شمس الدین التتمش‬), who had the titular name of Nasir Amir-ul-Mu'minin (ناصرامیر المؤمنین ‬) and reigned from 1211 to 1236. He shifted the capital from Lahore to Delhi and trebled the exchequer. He defeated Nasir-ud-Din Qabacha of Multan and Tajuddin Yildoz of Ghazni, who had declared themselves contenders of Delhi. Mongols invaded India in pursuit of Jalal-ud-din Mangabarni who was defeated at the Battle of Indus by Genghis Khan in 1221. After Genghis Khan's death, Iltutmish consolidated his hold on northern India by retaking many of the lost territories. In 1230, he built the Hauz-i-Shamsi reservoir in Mehrauli, and in 1231 he built Sultan Ghari, which was the first Islamic mausoleum in Delhi.
