Abstract:
Murshid Quli Khan was the first Nawab of Murshidabad, who ruled from the center of this state over Bengal, Bihar, and Orissa. He is considered the founder of the independent provincial government. Murshid Quli Khan minted coins in Murshidabad and built the famous Katra Mosque. He also promoted the Persian language and made it the official language of India. Beside the Great Katra Mosque, there was an artillery structure where the great cannon 'Jahan Kosha'—which is said to be made of a combination of eight metals including: gold, silver, copper, lead, zinc, mercury, iron, and tin—was located. This cannon is currently on public display in the Victoria Memorial.
Machine summary:
A century ago, the great Jahan Gusha cannon was mounted on a wheeled cart that had been surrounded and overtaken by Pipal trees, and now it has raised it about four feet (feet) off the ground, almost covering the entire body.
Sir Hasan Ali Mirza, Nawab Bahadur of Murshidabad, also enriched the collection of the Victoria Museum by donating manuscripts, decrees, treatises, paintings, various weapons, etc.
Finakin, Lord Curzon's minister from the Murshidabad court, sent a letter via Bakerkar—the Viceroy's special aide—to Curzon on March 2, 1902, stating: "I have shown your Excellency's note to the Nawab Bahadur and his Diwan and have given them sufficient time to think about it and say what kind of items they can donate to the Victoria Memorial ...
Conclusion Currently, the Persian inscriptions on the body of the Jahan Gusha cannon have been lost, and as mentioned, it is as if history has been erased and a part of the civilization and culture of a great nation has been consigned to oblivion.
