Reshmi Romal Movement ascribed to:

The Reshmi Romal Movement, also called the Silk Letter Conspiracy, was a daring effort against the British in India during World War I. With Mahmud Hassan at the helm, secret letters were written on silk to organize a rebellion against the British with the support of the Ottoman Empire and Afghanistan. The idea was to incite rebellions amongst the Indian army, but the British discovered and suppressed this move. Despite failing to succeed, this was a landmark moment in the history of revolutionary nationalism and secret rebellions in India.
