By which event, “boycott” in India was inspired in early 20th century?

The Boycott of American goods by Chinese has started in 1882 in response to the Chinese Exclusion Act of 1882. This was one important event which got its further developments in 1905-06. But it will not be right to say that only this event inspired the Bengalis. The leaders such as SN Banerjee had also inspired / educated the people about the impact of the political tools.
