The Emperor Shah Jahan built the Taj Mahal as a mausoleum for his beloved wife Mumtaz Mahal. Their son, Aurangzeb, ousted the Emperor from the throne. He, possibly, wanted to outshine his father particularly in Shah Jahan’s greatest achievement: the immortal Taj. Consequently, when Aurangzeb’s first wife, Dilras Banu Begum, died he decided to build a mausoleum for her in Aurangabad, Maharashtra, to replicate the Taj. His Bibi-Ka-Maqbara, built between 1657 and 1661 stands in a walled area of 137, 000 sq. metres. Though, to the casual glance, it looks very much like the Taj, this monument has not been made of white marble but is covered in plaster fashioned to resemble marble and is often referred to as the "poor man's Taj" or Mini Taj
