Shah Abbas II, Mughal-Persian Tensions (1668), and The Secured Frontier
Later in the century, during the reign of Shah Abbas II, tensions between the empires flared up once more, characterized by deliberate insults to Mughal envoys, overt threats of invasion, and high-stakes power maneuvering from the Safavid side.
