The Ghadar Party was founded by Indian immigrants with the stated goal of liberating India from British rule. With the outbreak of World War I, the Ghadar Party called on its cadre to travel to India and join the freedom struggle. Uprisings in military cantonments were planned by the Ghadar Party. Some Ghadarites also influenced the chiefs of the Princely States. Mandi in Himachal Pradesh was one such State. Nidhan Singh Chugga, the leader of the Ghadar Party, held numerous meetings in Mandi State and was successful in enlisting Mian Jawahar Singh, a state minister. However, when the plot failed, he was apprehended. In the Mandi Conspiracy Case, he was tried. British judges noted that in Mandi State, Mian Jawahar Singh assisted Ghadar Party members in staging an uprising. In or around the month of January 1915, a meeting was held at a spring near Barsu to discuss the manufacture of bombs and the collection of bomb materials. Mian Jawahar Singh promised men, arms, and bomb materials, and it was decided to assassinate the Superintendent and Wazir of the Mandi State, commit dacoities, imported men from Punjab, and that after conquering the Mandi and Suket States, they should proceed to Punjab and personally join the rebellion there. For assisting the Ghadar Party, Mian Jawahar Singh was sentenced to transportation for life and forfeiture of property under sections 121A, 122, and 302-115. He died later in Multan Jail.
