The house was established by a
Jain Bania named Hiranand Shah from
Nagaur,
Rajasthan, In 1713, Manikchand helped Prince
Farrukhsiyar financially to become the
Mughal Emperor. In award,
Farrukhsiyar conferred the title of
Jagat Seth on Manik Chand, This indicates the favour the family had gained at the
Mughal court. Roben Orme, the official historian of the British East India Company described Jagat Seth as the greatest banker and money changer known in the world at that time. The historian
Ghulam Hussain Khan believed that "their wealth was such that there is no mentioning it without seeming to exaggerate and to deal in extravagant fables". During the
Maratha invasions of Bengal, the
Bargi Maratha mercenaries plundered the mansion of the Jagat Seth, taking away 25 million rupees as booty.
Conspiracy against Siraj ud-Daulah Siraj ud-Daulah, the new Nawab of Bengal, alienated figures important to the interest of his state- including the Jagat Seth Mehtab Chand. The Nawab demanded a lavish tribute of 30 million rupees from the banker. Jagat Seth Mehtab Chand refused, and a result,
Siraj ud-Daulah hit him. The Jagat Seth and other wealthy bankers funded the British for the conspiracy. ==Decline==
