The Mosque was built by Mughal emperor, Shah Jahan’s daughter in 1648 A.D. It was constructed by more than 5000 workers. It was originally called Masjid-i-Jahan Numa, meaning ‘mosque commanding view of the world’.
Battle of Chausa was fought near Buxar. Humayun was badly defeated and Sher Khan adopted the title of Sher Shah. Humayun barely escaped with his life from the battle field.
