10 the sepoys or the soldiers of the bengal army in india rebelled against the east india company for the first time on may 10, 1857. why was the sepoy rebellion important in india's fight for independence from the british colonizers?

The sepoys were basically traitors for the Indians. SO, when the sepoys revolted against the East India Company, the Indians had more inspiration and power than before. That inspiration caused the indian independence. 

The Sepoy Mutiny was a violent and very bloody uprising against British rule in India in 1857. It is also known by other names: the Indian Mutiny, the Indian Rebellion of 1857, or the Indian Revolt of 1857.

In Britain and in the West, it was almost always portrayed as a series of unreasonable and bloodthirsty uprisings spurred by falsehoods about religious insensitivity.

In India it has been viewed quite differently. And events of 1857 have been considered the first outbreak of an independence movement against British rule.
