The critique that most directly challenges the argument that the Indian Rebellion of 1857 caused the birth of Indian nationalism is:
India saw a wide variety of responses to the rebellion including some groups allying with the British.
This critique suggests that the rebellion did not unite all Indians against colonial rule or foster a singular sense of nationalism; rather, different groups had varying interests and some even collaborated with the British, indicating a lack of cohesive national identity that would define later nationalist movements.
