Nadir Shah’s invasion
In 1739 Nadir Shah of Persia defeated Mughal forces at Karnal, entered Delhi and carried away immense wealth, including famous imperial treasures. The invasion damaged prestige, finances and confidence in Mughal military power.
Ahmad Shah Abdali
Ahmad Shah Abdali invaded repeatedly from Afghanistan. His campaigns affected Punjab and north India and contributed to continuing instability. His defeat of the Marathas at Panipat in 1761 checked them but did not restore Mughal authority.
Consequences
Invasions removed wealth, devastated regions and revealed the inability of the centre to protect subjects. Provincial rulers had further reason to rely on their own armies. Trade and agriculture were disrupted.
Historical weighting
The invasions were serious accelerators of decline, but they succeeded because internal weakness already existed. They should be explained as external shocks interacting with administrative, military and succession problems.
Chronology and connections
The visual summary for this lesson highlights the sequence or relationship between 1739 – Nadir Shah defeats Mughals, 1748 – Abdali raids begin, 1757 – Abdali occupies Delhi, 1761 – Third Battle of Panipat, 1760s – Mughal authority remains weak. These points should be used as an analytical framework rather than memorised as an isolated list. When revising Persian and Afghan invasions, connect each event or feature to an earlier cause, an immediate result and a longer-term consequence. This method helps distinguish chronology from causation and prevents an answer from becoming a narrative with no explanation.
Historical interpretation and judgement
Religious reform is interpreted differently according to the evidence selected. A movement may appear unsuccessful if judged only by territory or political power, yet more successful if judged by teaching networks, social discipline, community organisation and influence on later leaders. Candidates should therefore state the criterion of success, acknowledge regional limits and avoid claiming that an eighteenth- or nineteenth-century reformer consciously worked for a state that was not demanded until much later.
Historical source skill
Examine a court chronicle describing the sack of Delhi. What details might be vivid but unrepresentative of conditions elsewhere?
Examination tip
Use “accelerated” or “exposed” when judging invasions; they did not begin every Mughal problem.
