The following was not one of the capital cities of the Mughals:

Ajmer

The correct answer is Option (3) → Ajmer

Ajmer was not a Mughal Capital.

In the 1570s he decided to build a new capital, Fatehpur Sikri. One of the reasons prompting this may have been that Sikri was located on the direct road to Ajmer, where the dargah of Shaikh Muinuddin Chishti had become an important pilgrimage centre.

After 1707, following the death of Aurangzeb, the power of the dynasty diminished. In place of the vast apparatus of the empire controlled from Delhi, Agra or Lahore – the different capital cities – regional powers acquired greater autonomy. Yet symbolically the prestige of the Mughal ruler did not lose its aura. In 1857 the last scion of this dynasty, Bahadur Shah Zafar II, was overthrown by the British.
