The majestic fort in Agra, once the capital of the Mughal empire, neighbors the beautiful Taj Mahal. It was home to several generations of Mughal emperors, who ruled most of India from within its walls. These emperors included Shah Jehan, who built the Taj Mahal as a tribute to his deceased wife, and his son Aurangzeb, who imprisoned Shah Jehan in one--albeit beautiful--corner of Fort Agra with a view of the Taj Mahal. Why? Because Shah Jehan had squandered much of the Mughal treasury in the construction of the Taj Mahal.
