Revolt of 1857:
The Revolt of 1857, also known as the Indian Rebellion of 1857, was a significant uprising against British rule in India. The main reasons for this revolt were the introduction of new laws that were seen as disrespectful to Indian culture and religion, the economic exploitation of Indian farmers by British landlords, and the use of Indian soldiers in distant lands for the British army.

Deccan Uprising (1875-1882):
The Deccan Uprising was a series of protests and rebellions in the Deccan region of India against the British colonial rule. The main reasons for this uprising were the oppressive land revenue policies of the British, which led to the impoverishment of farmers, and the discriminatory treatment of Indian peasants by British officials.

Champaran Satyagraha (1917):
Although the Champaran Satyagraha took place after 1900, it is worth mentioning as it was a significant revolt against British rule in India. The main reason for this revolt was the forced indigo cultivation imposed by British landlords on Indian farmers, leading to widespread poverty and exploitation.
These revolts were sparked by a combination of economic, social, and political grievances against British colonial rule in India. They marked important milestones in the struggle for independence and paved the way for the eventual freedom of India from British imperialism.
