Condensed timeline version — for the fuller detailed version (Sayyid Brothers, Zamindari system, Macaulay's education policy, full Bengal Nawab history, etc.) see the "Disintegration of Mughal Rule" page.

Phase 1: Trade Foot-in-the-Door (1600s)

• 1600: British East India Company chartered by Queen Elizabeth I — purely commercial at first, no territorial ambitions
• 1619: Emperor Jahangir grants trading rights at Surat, Gujarat (spices, cotton, indigo, silk)
• Company sets up fortified trading posts: Madras (1639), Bombay (1668), Calcutta (1690)
• 1717: Emperor Farrukhsiyar issues a farman exempting the Company from Bengal customs duties + grants 38 villages near Calcutta — a major concession

Phase 2: From Merchants to Political Players (1740s–1757)

• Mughal central authority collapses after Aurangzeb's death (1707) → regional Nawabs become functionally independent → no strong power left to check foreign traders
• British & French East India Companies fight proxy wars in South India (Carnatic Wars), each backing rival local claimants — British come out ahead
• 1757 — Battle of Plassey: the real turning point. Robert Clive defeats Nawab Siraj-ud-Daulah of Bengal — not through military strength but through betrayal: Clive bribed the Nawab's own army chief, Mir Jafar, to hold his troops back mid-battle. Gives Britain its first real territorial + revenue base: Bengal

Phase 3: Legal Cover for Rule (1764–1765)

• 1764 — Battle of Buxar: British defeat a combined force of Mughal emperor Shah Alam II, the Nawab of Awadh, and the Nawab of Bengal — this time a direct win against a Mughal-backed coalition
• 1765: Shah Alam II forced to grant the Company Diwani rights (legal right to collect revenue) over Bengal, Bihar, and Orissa — the Mughal emperor himself legally hands over economic control of India's richest province
• Clive becomes the first British Governor of Bengal
• ⭐ This is the moment the Company stops being a trading firm and becomes a de facto ruling power, while the Mughal emperor keeps his throne in name only

Phase 4: Systematic Conquest (1765–1857)

• Bengal's revenue funds a private British army → expansion through war + alliance manipulation:
  • Defeats Mysore's Hyder Ali and Tipu Sultan across 4 Anglo-Mysore Wars (Tipu dies in battle, 1799)
  • Fights a series of Anglo-Maratha Wars, exploiting Maratha disunity (already weakened after losing the 3rd Battle of Panipat to Ahmad Shah Abdali in 1761)
  • Annexes the Sikh kingdom of Punjab (1839–1849) after Ranjit Singh's death fractures it
• Locks in control administratively: Permanent Settlement/Zamindari system (turns revenue collectors into a British-loyal landowning class) + Macaulay's English-medium education policy (creates an Anglicized administrative class)
• By 1823, Britain effectively controls two-thirds of India — the Mughal "emperor" still nominally sits in Delhi, drawing a British pension, with zero real power

Phase 5: Formal End of the Mughal Dynasty (1857–1858)
