India

India was seen as the "jewel in the crown" to the British because of their ability to produce raw materials and their population of about 300 million people, the British saw this as a potential market.  Indians were soon being oppressed and began to revolt with the Sepoy Mutiny.
The sepoys, who were Indian soldiers of the British army, heard rumor that the new cartridges that were to used in the guns were cased in raw beef and pork.  Being that Hindus believed that the cow was sacred and Muslims believed that pork was unclean refused to use them since they would have to put the cartridges into their mouths to loud it into the gun.  These Indians were put in jail and rebellion broke out.  This was not very successful, in fact it did the very opposite.  Instead of having just the  East India Company being in India, the British started sending troops to enforce them.
