What were the causes which led to the Battle of Plassey in 1756?yes! i want to have a whole mind map plus a proper and authentic explanation...

By the early 18th century, the British east india
company had a strong presence in India with the three main stations of Fort st.George in
Madras, Fort William in Calcutta and Bombay castle in western India. These stations were
independent presidencies governed by a President and a Council, appointed by the Court
of Directors in England. The British adopted a policy of allying themselves with various
princes and Nawabs, promising security against usurpers and rebels. The Nawabs often
gave them concessions in return for the security. By then, all rivalry had ceased
between the British East India Company and the Dutch or Portugese. The French had also
established an East India Company under Louis XIV and had two important stations in
India –Chandergarh in Bengal and Pondichery on the Carnatic coast, both governed by the
presidency of Pondicherry. The French were a late comer in India trade, but they quickly
established themselves in India and were poised to overtake Britain for
control.
