Who initiated the construction of the famous Qutub Minar in Delhi near the end of the 12th century?
The Qutub Minar was commissioned by Qutb-ud-din Aibak in 1199 CE. It was built to honor the famous Sufi saint Qutbuddin Bakhtiar Kaki. Aibak could only complete the basement level before his death. Later, Iltutmish added three more stories, and after a lightning strike in 1368, Firoz Shah Tughlaq replaced the top story and added two more. [Memory Trick: The building 'Qutub' Minar was started by 'Qutb'-ud-din himself.]
