who laid the foundation of the delhi sultanate
Delhi Sultanate The wave of raids on north Indian and western Indian kingdoms by Muslim warlords continued after Mahmud of Ghazni.[26] The raids did not establish or extend permanent boundaries of their Islamic kingdoms. The Ghurid sultan Mu'izz ad-Din Muhammad Ghori, commonly known as Muhammad of Ghor, began a systematic war of expansion into north India in 1173.[27] He sought to carve out a principality for himself by expanding the Islamic world.[23][28] Muhammad of Ghor sought a Sunni Islamic kingdom of his own extending east of the Indus river, and he thus laid the foundation for the Muslim kingdom called the Delhi Sultanate.[23] Some historians chronicle the Delhi Sultanate from 1192 due to the presence and geographical claims of Muhammad Ghori in South Asia by that time.[29]
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.
