Sepoy Mutiny
In May of 1857 soldiers of the Bengal Army shot their British officers and marched on Delhi. The mutiny encouraged several other parts of India to rebel as well and soon the British presence in India was considerably reduced until forces were able to launch offenses that helped restore Imperial power in 1858. The Indians rebelled in large part because their way of life, customs, and religions were all largely being disregarded by their British rulers which they found depply offensive.
