The Hindi Association is set up in Portland, USA under the leadership of Lala Hardayal, which transforms into the Ghadar Party later that year. The Ghadar Party formed by Indian immigrants aims to further the cause of Indian independence and overthrow British rule in India through revolution.

The Komagata Maru incident in 1914 influences the course of the Ghadar movement. Baba Gurdit Singh, encouraged by the Canadian Supreme Court’s decision allowing entry to 35 Indians who had not made a continuous journey, charters a ship to Vancouver with 376 Indian passengers. Ghadar activists visit the ship at Yokohama, Japan, distribute literature, and give lectures. On its arrival in Vancouver, the ship, Komagata Maru is not permitted to anchor and is forced out of Canadian waters. The First World War breaks out before the ship reaches Yokohama and the British Government passes orders disallowing passengers from disembarking anywhere on the way, except at Calcutta.
