Why was the role of overseas Indians decisive in the Ghadar Movement?

Correct answer: Because the movement was based on networks of Indians abroad

Direct answer: Option A is correct. The Ghadar Movement depended heavily on Indians living abroad because those communities created communication, fundraising, publishing, and recruitment networks beyond the immediate control of the colonial government. The reasoning is: migrants in North America and elsewhere faced racial discrimination and remained connected to India; revolutionary activists used newspapers such as Ghadar and overseas meetings to spread the call for armed opposition; people and resources were then directed toward anti-colonial action. Option A works because the overseas network was central to the movement’s organisation and reach. Option B is wrong because temple entry was a different social-reform issue. Option C is wrong because the Dandi March belonged to Gandhi’s Salt Satyagraha, not the Ghadar Movement. Option D is wrong because the Indigo Commission concerned indigo cultivation and was not the Ghadar organisation. Lala Har Dayal is a useful associated name, though the movement involved many activists. Memory cue: Ghadar means overseas Indian revolutionary networks against colonial rule.
