Jam-i-Jahan-Numa (lit.'The world-revealing cup, i.e. Cup of Jamshid') was the first known Urdu-language newspaper.[1] It was established in March 1822 in Kolkatta by Harihar Datta. From its eighth issue, it began to be published in Persian as well, and eventually became an exclusively Persian-language newspaper. It operated until 1845. During its lifetime, the newspaper received support from the British colonial government.[2] Famed poet Ghalib criticized the newspaper in a letter to a friend, accusing it to often be inaccurate and unreliable.[3]
