On whose coins the name of the last Caliph of Baghdad appeared for the first time?

Iltutmish
- Shams ud-Din Iltutmish was the third of the Mamluk kings who ruled the former Ghurid territories in northern India.
- He was the first Muslim sovereign to rule from Delhi and is thus considered the effective founder of the Delhi Sultanate.
- Sold into slavery as a young boy, Iltutmish spent his early life in Bukhara and Ghazni under multiple masters.
- In the late 1190s, the Ghurid slave-commander Qutb al-Din Aibak purchased him in Delhi, thus making him the slave of a slave. Iltutmish rose to prominence in Aibak's service and was granted the important iqta' of Badaun.
- His military actions against the Khokhar rebels in 1205-1206 gained the attention of the Ghurid Emperor Mu'izz ad-Din, who manumitted him even before his master Aibak was manumitted.
- The name of the last Caliph of Baghdad who appeared for the first time on coins was Illtutmish.

Qutbuddin Aibak
- Qutb al-Din Aibak was a general of the Ghurid king Mu'izz ad-Din Muhammad Ghori.
- He was in charge of the Ghurid territories in northern India, and after Mu'izz ad-Din's death, he became the ruler of an independent kingdom that evolved into the Delhi Sultanate ruled by the Mamluk dynasty.
- A native of Turkestan, Aibak was sold into slavery as a child.
- He was purchased by a Qazi at Nishapur in Persia, where he learned archery and horse-riding among other skills.
- He was subsequently resold to Mu'izz ad-Din in Ghazni, where he rose to the position of the officer of the royal stables.
- During the Khwarazmian-Ghurid wars, he was captured by the scouts of Sultan Shah; after the Ghurid victory, he was released and highly favoured by Mu'izz ad-Din.
Alauddin Khilji

- Alauddin instituted a number of significant administrative changes, related to revenues, price controls, and society.
- He is noted for repulsing the Mongol invasions of India.
- Alauddin was a nephew and a son-in-law of his predecessor Jalaluddin.

- After his predecessor and uncle, Muiz ud-Din Bahram was murdered by the army in 1242 after years of disorder, the chiefs chose for him to become the next ruler.
- However, he was more of a puppet for the chiefs and did not actually have much power or influence in the government. Instead, he became infamous for his fondness for entertainment and wine.
- Like his predecessor, he was considered "incompetent and worthless."
