The Indian campaigns of Muhammad of Ghor were a series of invasions by the Ghurid ruler Muhammad of Ghor (c.1173-1206) in the last quarter of the twelfth and early decade of the thirteenth century which lead to the widespread expansion of the Ghurid empire in the Indian subcontinent. During his campaigns in India, Mu'izz al-Din extirpated several local dynasties which included the Qarmatians of Multan, Ghaznavids of Lahore, Chauhans of Ajmer, Tomaras of Delhi, Jadauns of Bayana and possibly the Gahadavalas of Kannauj as well.
