The First War of Indian Independence, also known as the Sepoy Mutiny or First War of Independence (1857), was a significant event in the history of India’s struggle for freedom. The causes were manifold, including:

• Political Causes: The annexation of Indian states under the Doctrine of Lapse and the weakening of native rulers stirred discontent among the Indian princely states.

• Economic Causes: British economic policies drained India's wealth, leading to widespread poverty and economic exploitation, especially among farmers and artisans.

• Military Causes: The introduction of the Enfield rifle cartridges, which were rumored to be greased with cow and pig fat, offended both Hindu and Muslim sepoys, leading to the revolt.

• Social and Religious Causes: The British attempts to interfere with traditional Indian customs, such as the abolition of Sati and the introduction of laws allowing widow remarriage, caused resentment.

• Cultural Causes: The British portrayed Indian culture in a derogatory manner, causing a feeling of humiliation and fostering nationalist sentiment.

The 1857 revolt marked the beginning of a national awakening, though it was suppressed by the British, yet it laid the foundation for future organized resistance.
