Question

How did the foreign invasions by Nadir Shah and Ahmed Shah Abdali expose the vulnerability of Mughal empire?​

Answer 1

$\huge\mathfrak\red{answer}$

The power of Mughals was declining at that time and the central power had no control over far flung provinces, which made foreign invasions easy for the enemies of Mughal rulers. Nadir shah became ruler of Persia when Shah Tahmasp last ruler of Safwid dynasty died in 1736.
