State any three main political causes that led to the Great Uprising of 1857.

Three main political causes that led to the Great Uprising of 1857 were:

1. The British policies of expansion like Doctrine of Lapse, Subsidiary Alliance, outright wars and control of territory on the pretext of alleged misrule was one of the major grievances of the Indian rulers.
2. The successors of Bahadur Shah Zafar were not allowed to use the Red Fort as their palace and also they were not allowed to use imperial titles with their names. This decision hurt the feelings of Muslims causing Zeenat Mahal, the wife of Bahadur Shah Zafar to start plotting against the British.
3. Nana Saheb was adopted son of Baji Rao II (the last Peshwa) but he was denied the pension by British which they were paying to Baji Rao II. Nana Saheb was forced to live at Kanpur, far away from his family seat at Poona. This was widely resented in the Maratha region.
