Lala Hardayal was a key leader and the first General Secretary of the Ghadar Party. Following his arrest in March 1914 and subsequent departure from the United States, the leadership roles evolved. Bhai Santokh Singh was an important leader and figure within the party who took on significant responsibilities, including serving as Secretary, in the period after Hardayal left. Sohan Singh Bhakna was the founding President of the Hindi Association (Ghadar Party). Ram Nath Puri and Taraknath Das were also associated with Indian revolutionary activities abroad but were not Hardayal's direct successor as Secretary in the central leadership structure of the Ghadar Party in the way Santokh Singh was.
