Final answer:
The specific conditions upon which Kapur Singh accepted Nawabship when a Jagir was offered to the Sikhs by the Lahore Governor are not detailed within the provided references. However, Sikh-Mughal relations, characterized by significant tension during Aurangzeb's rule, would have influenced the dealings between the Lahore Governor and the Sikh leader.
Step-by-step explanation:
On the historical account of the Sikhs during Aurangzeb's reign, Kapur Singh played an influential role as a leader. The conditions upon which Kapur Singh accepted Nawabship, when the Jagir was offered to the Sikhs by the Lahore Governor, are not specified in the provided references. It's important to note that the Sikhs had been under persecution during the Mughal rule, particularly under Emperor Aurangzeb, who clashed with Sikhs in northern India and sought to control the succession of Sikh Gurus, thereby causing friction and resistance against Mughal authority. While the references describe various significant historical interactions between different rulers and the Sikhs, the specific conditions of Kapur Singh's acceptance of Nawabship were likely influenced by the broader context of Mughal-Sikh relations at the time. However, without explicit information from the provided references, a detailed answer regarding Kapur Singh's conditions cannot be confidently given.
