The East India Company (EIC) was an English, and later British, joint-stock company that was founded in 1600 and dissolved in 1874. It was formed to trade in the Indian Ocean region, initially with the East Indies (which included the Indian subcontinent and Southeast Asia), and later with East Asia. The company gained control of large parts of the Indian subcontinent and Hong Kong. At its peak, the company was the largest corporation in the world by various measures and had its own armed forces in the form of the company's three presidency armies, totalling about 260,000 soldiers, twice the size of the British Army at certain times.

Originally chartered as the "Governor and Company of Merchants of London Trading into the East-Indies," the company rose to account for half of the world's trade during the mid-1700s and early 1800s, particularly in basic commodities including cotton, silk, indigo dye, sugar, salt, spices, saltpetre, tea, gemstones, and later opium. The company also initiated the beginnings of the British Raj in the Indian subcontinent.

The company eventually came to rule large areas of the Indian subcontinent, exercising military power and assuming administrative functions. Company-ruled areas in the region gradually expanded after the Battle of Plassey in 1757 and by 1858 most of modern India, Pakistan and Bangladesh was either ruled by the company or princely states closely tied to it by treaty. Following the Sepoy Rebellion of 1857, the Government of India Act 1858 led to the British Crown assuming direct control of present-day Bangladesh, Pakistan, Myanmar, Sri Lanka and India in the form of the new British Indian Empire.

The company subsequently experienced recurring problems with its finances, despite frequent government intervention. The company was dissolved in 1874 under the terms of the East India Stock Dividend Redemption Act enacted one year earlier, as the Government of India Act had by then rendered it vestigial, powerless, and obsolete. The official government machinery of the British Empire had assumed its governmental functions and absorbed its armies.

In 1577, Francis Drake set out on an expedition from England to plunder Spanish settlements in South America in search of gold and silver. Sailing in the Golden Hind he achieved this, and then sailed across the Pacific Ocean in 1579, known then only to the Spanish and Portuguese. Drake eventually sailed into the East Indies and came across the Moluccas, also known as the Spice Islands, and met Sultan Babullah. In exchange for linen, gold, and silver, the English obtained a large haul of exotic spices, including cloves and nutmeg. Drake returned to England in 1580 and became a hero; his circumnavigation raised an enormous amount of money for England's coffers, and investors received a return of some 5,000 percent. Thus started an important element in the eastern design during the late sixteenth century.

Soon after the Spanish Armada's defeat in 1588, the captured Spanish and Portuguese ships and cargoes enabled English voyagers to travel the globe in search of riches. London merchants presented a petition to Elizabeth I for permission to sail to the Indian Ocean. The aim was to deliver a decisive blow to the Spanish and Portuguese monopoly of far-eastern trade. Elizabeth granted her permission and in 1591, James Lancaster in the Bonaventure with two other ships, financed by the Levant Company, sailed from England around the Cape of Good Hope to the Arabian Sea, becoming the first English expedition to reach India that way. Having sailed around Cape Comorin to the Malay Peninsula, they preyed on Spanish and Portuguese ships there before returning to England in 1594.

The biggest prize that galvanised English trade was the seizure of a large Portuguese carrack, the Madre de Deus, by Walter Raleigh and the Earl of Cumberland at the Battle of Flores on 13 August 1592. When she was brought in to Dartmouth she was the largest vessel ever seen in England and she carried chests of jewels, pearls, gold, silver coins, ambergris, cloth, tapestries, pepper, cloves, cinnamon, nutmeg, benjamin (a highly aromatic balsamic resin used for perfumes and medicines), red dye, cochineal and ebony. Equally valuable was the ship's rutter (mariner's handbook) containing vital information on the China, India, and Japan trade routes.

In 1596, three more English ships sailed east but all were lost at sea. A year later however saw the arrival of Ralph Fitch, an adventurer merchant who, with his companions, had made a remarkable nine year overland journey to Mesopotamia, the Persian Gulf, the Indian Ocean, India and Southeast Asia. Fitch was consulted on Indian affairs and gave even more valuable information to Lancaster.
