Explanation:

To fight the British, leadership and organisation were required. For these the rebels sometimes turned to those who had been leaders before the British conquest. One of the first acts of the sepoys of Meerut, as we saw, was to rush to Delhi and appeal to the old Mughal emperor to accept the leadership of the revolt. This acceptance of leadership took its time in coming.
Bahadur Shah‘s first reaction was one of horror and rejection. It was only when some sepoys had moved into the Mughal court within the Red Fort, in defiance of normal court etiquette, that the old emperor, realising he had very few options, agreed to be the nominal leader of the rebellion. Elsewhere, similar scenes were enacted though on a minor scale. In Kanpur,the sepoys and the people of the town gave Nana Sahib, the successor to Peshwa Baji Rao II,no choice save to join the revolt as their leader. In Jhansi, the rani was forced by the popular pressure around her to assume the leadership of the uprising.
So was Kunwar Singh, a local zamindar in Arrah in Bihar. In Awadh, where the displacement of the popular Nawab Wajid Ali Shah and the annexation of the state were still very fresh in the memory of the people, the populace in Lucknow celebrated the fall of British rule by hailing Birjis Qadr, the young son of the Nawab, as their leader. Not everywhere were the leaders people of the court – ranis, rajas, nawabs and taluqdars.Often the message of rebellion was carried by ordinary men and women and in places by religious men too. From Meerut, there were reports that a fakir had appeared riding on an elephant and that the sepoys were visiting him frequently. In Lucknow, after the annexation of Awadh, there were many religious leaders and self-styled prophets who preached the destruction of British rule.
Elsewhere, local leaders emerged, urging peasants, zamindars and tribals to revolt. Shah Mal mobilised the villagers of pargana Barout in Uttar Pradesh; Gonoo, a tribal cultivator of
Singhbhum in Chotanagpur, became a rebel leader of the Kol tribals of the region.
