Answer:

Step-by-step explanation:
The Sepoy Rebellion is also known as India's First War of Independence. When new rifles were introduced to the sepoys, they learned that they had to bite the cartridge off the rifle. The sepoys were upset because they believed the cartridges were greased with pork and beef fat. Pork is regarded unclean by Muslims, and cow is considered a sacred animal for Hindus. The Sepoy Rebellion was not successful, but it inspired many revolts that finally led to India's independence.
