Concept:
• The Revolt of 1857 was widespread across North and Central India, but its intensity varied significantly by region.
• Many princely states, due to their diplomatic treaties or lack of support for the mutineers, remained largely peaceful.
Step 1: Identifying centers of the revolt
Gwalior was a major center where the rebels, led by Tatya Tope and Rani Lakshmibai, made a significant stand.
Arrah (in Bihar) saw intense rebellion led by Kunwar Singh, a local zamindar who became a key figure in the uprising.
Singhbhum was another region where local leaders and tribals actively participated against British authority.
Step 2: Analyzing the exception
Hyderabad, under the Nizam, maintained its allegiance to the British, preventing the revolt from becoming a large-scale organized movement in that territory.
While there were minor incidents of dissent, it did not reach the level of a "major center" like the others listed.
