NBSE Class 9 Social Science Chapter 4: Indian National Movement

It is ironic that the establishment of British rule in India gave birth to Nationalism in India. First and foremost, India was unified politically for the first time under the British. A uniform legal system, uniform currency, and a uniform system of administration made Indians think of India as one nation. There was a rediscovery of India’s glorious past which revived pride and self-respect among the Indians and gave renewed strength to the Indian National Movement.

Climate is the long-term effect of the Sun’s radiation on the rotating Earth’s surface and atmosphere.
