Who invented Mysorean rockets? When were they used?

Answer:

Mysorean rockets, the first known iron-cased rockets, were developed in the Indian region of Mysore due to the funding of its leader, Hyder Ali in the 18th century. These rockets were used effectively against the British East India Company, who eventually appropriated the technology and used it in their own army.
