The siege of Golconda occurred in January 1687, when the Mughal Emperor Aurangzeb led his forces to besiege the Qutb Shahi dynasty at Golconda Fort, home of the Kollur Mine. The siege of Golconda lasted 8 months, and on various occasions it pushed the massive Mughal army to its limits. The Golconda Fort was considered to be an impregnable fort on the Indian subcontinent. At the end of the Siege, Aurangzeb and the Mughals entered Golconda in a decisive victory.
