The British Raj lit. "reign" in Hindustani is the name given to the period of British colonial rule in the Indian subcontinent between 1858 and 1947
The system of governance was instituted in 1858, when the rule of the British East India Company was transferred to the Crown in the person of Queen Victoria (and who, in 1876, was proclaimed Empress of India), and lasted until 1947, when the British Indian Empire was partitioned into two sovereign dominion states, the Union of India (later the Republic of India) and the Dominion of Pakistan (later the Islamic Republic of Pakistan, the eastern half of which, still later, became the People's Republic of Bangladesh).
ollowing the Indian Rebellion of 1857, the Act for the Better Government of India (1858) made changes in the governance of India at three levels: in the imperial government in London, in the central government in Calcutta, and in the provincial governments in the presidencies (and later in the provinces).
During the British Raj, India experienced some of the worst famines ever recorded, including the Great Famine of 1876–78, in which 6.1 million to 10.3 million people died and the Indian famine of 1899–1900, in which 1.25 to 10 million people died. Recent research, including work by Mike Davis and Amartya Sen, attribute these famines directly to British policy in India.
The first cholera pandemic began in Bengal, then spread across India by 1820. 10,000 British troops and countless Indians died during this pandemic.] Deaths in India between 1817 and 1860 are estimated to have exceeded 15 million persons. Another 23 million died between 1865 and 1917. The Third Pandemic of plague started in China in the middle of the 19th century, spreading disease to all inhabited continents and killing 10 million people in India alone. Waldemar Haffkine, who mainly worked in India, was the first microbiologist who developed and used vaccines against cholera and bubonic plague. In 1925, the Plague Laboratory in Bombay was renamed the Haffkine Institute.
In the second half of the 19th century, both the direct administration of India by the British crown and the technological change ushered in by the industrial revolution, had the effect of closely intertwining the economies of India and Britain. In fact many of the major changes in transport and communications (that are typically associated with Crown Rule of India) had already begun before the Mutiny. Since Dalhousie had embraced the technological change then rampant in Britain, India too saw rapid development of all those technologies. Railways, roads, canals, and bridges were rapidly built in India and telegraph links equally rapidly established in order that raw materials, such as cotton, from India's hinterland could be transported more efficiently to ports, such as Bombay, for subsequent export to England.
Likewise, finished goods from England were transported back just as efficiently, for sale in the burgeoning Indian markets. However, unlike Britain itself, where the market risks for the infrastructure development were borne by private investors, in India, it was the taxpayers—primarily farmers and farm-labourers—who endured the risks, which, in the end, amounted to £50 million. In spite of these costs, very little skilled employment was created for Indians. By 1920, with the fourth largest railway network in the world and a history of 60 years of its construction, only ten per cent of the "superior posts" in the Indian Railways were held by Indians.
The Indian railways system, by 1900, provided India with social savings of 9% of India's national income (about 1.2 billion rupees).
The rush of technology was also changing the agricultural economy in India: by the last decade of the 19th century, a large fraction of some raw materials—not only cotton, but also some food-grains—were being exported to faraway markets. Consequently, many small farmers, dependent on the whims of those markets, lost land, animals, and equipment to money-lenders. More tellingly, the latter half of the 19th century also saw an increase in the number of large-scale famines in India. Although famines were not new to the subcontinent, these were particularly severe, with tens of millions dying, and with many critics, both British and Indian, laying the blame at the doorsteps of the lumbering colonial administrations
