CORE Bengal as the first bridge from commerce to conquest
The Battle of Plassey on 23 June 1757 marks the first decisive political turn in Company rule because Robert Clive defeated Siraj ud-Daulah in Bengal and Mir Jafar was installed as a dependent nawab. Plassey did not create a regular empire overnight, but it gave the East India Company control over Bengal's revenue-bearing politics and made private trade, military pressure and court intrigue work together. The Battle of Plassey therefore belongs with the Bengal treasury, the Fort William interest and the shift from coastal factories to inland authority. Rajasthan's later experience with Company agents in Ajmer and Marwar shows the same pattern in another region: a commercial power became a political arbiter before it appeared as a direct ruler.
The Battle of Buxar on 22 October 1764 made the Bengal position firmer. The Company's army defeated Mir Qasim of Bengal, Shuja-ud-Daula of Awadh and the Mughal emperor Shah Alam II; the result led to the Company's diwani rights in Bengal, Bihar and Orissa in 1765. Buxar matters more than a battlefield list because it gave legal revenue authority to a corporation that still claimed to be only a trading body. The same revenue logic later entered Rajputana through tribute, loans and political agency, and Rajasthan's Aauwa and Bijolia memories grew in a world already shaped by this Company state.
