The Jagat Seths belongs to Jain family and the title of the eldest son of the family. The family sometimes referred to as the House of Jagat Seth, were a wealthy business, banking and money lender family from Murshidabad, Bengal region in the eastern part of the Indian subcontinent, during the time of Nawab Siraj ud-Daulah.^[1]

Jagat Seth was a title conferred by the Nawab of Bengal and can be interpreted as "banker or merchant of the world".^[2] House of Jagat Seth Museum contains personal possessions of Jagat Seth and his family including coins of the bygone era, muslin and other extravagant clothes, and Banarasi saris embroidered with gold and silver threads.

Jagat Seth, also the title for the powerful moneylender family he belonged to, looked after the mint and treasury accounts of Bengal during the Nawabi period. He played a key role in the conspiracy involving the imprisonment and ultimate killing of Nawab Siraj ud-Daulah. His house, complete with a secret tunnel as well as an underground chamber, where illegal trade plans were hatched, is what has been converted into the aforementioned museum. It is said that the amount of wealth he had back then was greater than the wealth of all banks of England put together.

Jagat Seth Mahtab Rai and his cousin Maharaj Swaroop Chand were captured and shot dead on the orders of Mir Qasim shortly before the Battle of Buxar in 1764. Jagat Seth was considered to be a traitor as he financed the British during the Battle of Plassey, which led to the death of Siraj ud-Daulah and the eventual start of the British Raj.
