Explanation: The Ghadr Party was a revolutionary group organised around a weekly newspaper The Ghadr with its headquarters at San Francisco and branches along the US coast and in the Far East.

• These revolutionaries included mainly ex-soldiers and peasants who had migrated from the Punjab to the USA and Canada in search of better employment opportunities.
• They were based in the US and Canadian cities along the western (Pacific) coast. Pre-Ghadr revolutionary activity had been carried out by Ramdas Puri, G.D. Kumar, Taraknath Das, Sohan Singh Bhakna and Lala Hardayal who reached there in 1911.
• To carry out revolutionary activities, the earlier activists had set up a ‘Swadesh Sevak Home’ at Vancouver and ‘United India House’ at Seattle. Finally in 1913, the Ghadr was established.
