The Indian Rebellion of 1857 began as a mutiny of sepoys of the East India Company's army on 10 May 1857, in the cantonment of the town of Meerut, and soon escalated into other mutinies and civilian rebellions largely in the upper Gangetic plain and central India, with the major hostilities confined to present-day Uttar Pradesh, Bihar, northern Madhya Pradesh, and the Delhi region. The rebellion posed a considerable threat to East India Company power in that region, and was contained only with the fall of Gwalior on 20 June 1858. The rebellion is also known as India's First War of Independence, the Great Rebellion, the Indian Rebellion, the Indian Mutiny, the Revolt of 1857, the Rebellion of 1857, the Uprising of 1857, the Sepoy Rebellion and the Sepoy Mutiny.
The Indian Rebellion of 1857 occurred as the result of an accumulation of factors over time, rather than any single event.
The sepoys were local soldiers, the majority Hindu or Muslim, that were recruited into the Company's army. Just before the Rebellion there were over 300,000 sepoys in the army, compared to about 50,000 British. The forces were divided into three presidency armies: Bombay, Madras, and Bengal. The Bengal Army recruited higher castes, such as "Rajputs and Bhumihar Brahmins, mostly from the Awadh and Bihar regions and even restricted the enlistment of lower castes in 1855. In contrast, the Madras Army and Bombay Army were "more localized, caste-neutral armies" that "did not prefer high-caste men." The domination of higher castes in the Bengal Army has been blamed in part for initial mutinies that led to the rebellion.
The American Revolution was a political upheaval that took place between 1765 and 1783 during which the Thirteen American Colonies broke from the British Empire and formed an independent nation, the United States of America. The American Revolution was the result of a series of social, political, and intellectual transformations in American society, government and ways of thinking. Starting in 1765 the Americans rejected the authority of Parliament to tax them without elected representation; protests escalated as in the Boston Tea Party of 1773, and the British imposed punitive laws—the Intolerable Acts—on Massachusetts in 1774. In 1774 the Patriots suppressed the Loyalists and expelled all royal officials. Each colony now had a new government that took control. The British responded by sending combat troops to re-establish royal control. Through the Second Continental Congress, the Patriots fought the British in the American Revolutionary War (1775 - 1783).
The peace treaty with Britain, known as the Treaty of Paris, gave the U.S. all land east of the Mississippi River and south of the Great Lakes, though not including Florida (On September 3, 1783, Britain entered into a separate agreement with Spain under which Britain ceded Florida back to Spain.) The British abandoned the Indian allies living in this region; they were not a party to this treaty and did not recognize it until they were defeated militarily by the United States. Issues regarding boundaries and debts were not resolved until the Jay Treaty of 1795. Since the blockade was lifted and the old imperial restrictions were gone, American merchants were free to trade with any nation anywhere in the world, and their businesses flourished.
