Khankhoje's earliest nationalist work abroad dates back to the time around 1908 when he, along with
Pandit Kanshi Ram founded the Indian Independence League in
Portland, Oregon. His works also brought him close to other Indian nationalists in United States at the time, including
Tarak Nath Das. In the years preceding World War I, Khankhoje was one of the founding members of the Pacific coast Hindustan association, and subsequently founded the Ghadar Party. He was at the time one of the most influential members of the party. He met
Lala Har Dayal in 1911. He also enrolled at one point in a West Coast military academy.
Activities during World War I Through World War I, Khankhoje was intricately involved in the
Hindu–German Conspiracy when he was involved in the plans for the mutiny. He visited Europe during the war and subsequently went to
Mesopotamia along with other members of what was the
Berlin Committee. In the summer of 1915, he worked clandestinely among troops of the Indian expeditionary force, spreading nationalist literature and hoping to incite a mutiny. Through the course of the war, Khankhoje made his way through Turkey and Persia under different Muslim guises as far as Baluchistan, spreading Ghadarite propaganda en route. He is known to have attempted insurrections and raised at the Iran-Baluchistan border while
Mahendra Pratap's
Indo-German expedition attempted to rally the Afghan Emir
Habibullah Khan against British India. Towards the end of the war, Khankhoje, like most of the members of the Berlin committee, began turning towards communism. He is known to have been in
Soviet Union in company of the earliest Indian communist, including
Virendranath Chattopadhyaya,
M. P. T. Acharya,
M. N. Roy,
Abdur Rab Barq.For his nationalist work at the time, Khankhoje was banned from returning to India as a highly dangerous individual. ==Academic career==
