During the time of the Second World War Indian people began to migrate to Canada and America.
The government of Canada was heavily under the influence of the British government.
It rejected the entry of Indian migrants. It did not allow ‘Kamagata Maru’ a steamship with Indian migrants aboard under the leadership of Baba Gurudit Singh, to anchor in the Canadian port of Vancouver.
People on this ship returned to India. On their return journey, Kamagata Maru reached the port of ‘Bajbaj’ near Kolkata. There the British officers ordered Indian passengers to return immediately to their own towns and villages.
But the Indians did not follow the orders so the British officers began to shoot and 30 Indian passengers died in it.
This incidence of cruelty on the part of British officers created public outcry throughout India.
