¹ Tughluq was the personal name of Ghiyās-ud-dīn, but has been applied, both by Eastern and Western historians, to the dynasty founded by him, as though it were a patronymic. It is usually transliterated Tughlaq, but I follow Ibn Batūtah, who is explicit on the point, and who, though not always a safe guide in the matter of proper names, must have known how the name was pronounced at Delhi in his time.
