Who initiated the silk letter movement?

The silk letter movement was initiated by Ubaid Ullah Sindhi along with other leaders of the Deoband movement during the early 20th century. Its objective was to overthrow British colonial rule in India by seeking support from foreign powers including Afghanistan and the Ottoman Empire. The movement derived its name from the use of silk cloth to write secret messages to avoid detection. Although it was ultimately suppressed by British authorities it demonstrated the determination of Indian revolutionaries to achieve independence. The silk letter movement remains a notable example of resistance in the subcontinent’s freedom struggle.
