In 1644 there was an accident in Agra, the capital of the Mughal Empire. The favourite daughter of Emperor, Shah Jahan, was severely burnt when her dress caught fire. Many doctors tried to help her, but none succeeded. One of the courtiers informed the Emperor of some traders in Surat from a far-away land, who had a skilled medicine man with them. Messengers were quickly dispatched to Surat. They brought back one Gabriel Boughton, surgeon of an East India Company ship. The surgeon was able to successfully heal the daughter. Pleased, the Emperor promised him whatever reward he may desire. May be because of company loyalty or simply a lack of imagination, Boughtan asked for permission for the East India Company to trade in Bengal. At the time, India represented close to 25% of the world’s GDP, second only to China, while Britain had a paltry 2%. Bengal was the richest of Indian provinces. Trading with it could be an immensely profitable opportunity for the Company. The Emperor granted the doctor’s wish and soon first British trading post of opened in a village close to the town of Calcutta.
One hundred and twelve years later, Bengal looked very different. It was now ruled by a Nawab in Murshidabad, who was formally a servant of the Emperor in Delhi but retained de facto independence. The British controlled entire town Calcutta, defended by Fort William. Bengal also had towns of other European powers like the French and the Dutch, but the British settlement was the most wealthy and prosperous of them.
In the summer of 1755 the Nawab, Alivirdi, was dying. For the last few years he had been working to ensure the succession of his favourite grandson 21-years-old Siraj-uddaula. He had even made his general, Mir Jafar, swear an oath of loyalty to his grandson on Koran. Yet when Alivirdi died, Siraj-uddaula’s hold on power was far from confirmed. On the one hand, his own family members, including his aunt, conspired against him. On the other, the Emperor in Delhi kept threatening to march on Bengal and take it back. Even the Europeans, who seemed to be getting exorbitantly rich and powerful through trade, posed a threat to his rule.
