to be a name of Prithviraj (although some scholars believe him to be a distinct Tomara king), it is possible that Prithviraja's coins were called "Delhiwalas" not because they were minted in Delhi, but because they were used in Delhi after the city became a major Ghurid garrison. Other Theories Alexander Cunningham's classified the site into older ("Lal Kot") and newer ("Qila Rai Pithora") parts attributed to the Tomaras and the Chahamanas respectively, but later archaeological excavations have cast doubt on this classification. Carr Stephen (1876) considered "Lal Kot" only a palace, and used the name "Qila Rai Pithora" to describe the pre-Sultanate fortification at the site. B. R. Mani (1997) referred to the site as "Lal Kot", using the term "Qila Rai Pithora" to describe a fortification wall possibly built by the Chahamanas. Catherine B. Asher (2000) describes Qila Rai Pithora as Lal Kot enlarged with rubble walls and ramparts. She theorizes that Qila Rai Pithora served as a city, while Lal Kot remained the citadel. Qila Rai Pithora, which was twice as large as the older citadel, had more massive and higher walls, and the combined fort extended to six and a half km. Asher states that after the Ghurid conquest of the Chahamana kingdom in 1192 CE, the Ghurid governor Qutb al-Din Aibak occupied Qila Rai Pithora, and renamed it to "Dilhi" (modern Delhi), reviving the site's older name. However, Cynthia Talbot (2015) notes that the term "Qila Rai Pithora" first appears in the 16th-century text Ain-i-Akbari, and the older texts use the term "Dehli" to describe the site. Aibak and his successors did not extend or change the fort structure.
