During the Swadeshi movement in Bengal, a tricolour flag (red, green and yellow) was designed. It had eight lotuses representing eight provinces of British India, and a crescent moon, representing Hindus and Muslims. By 1921, Gandhiji had designed the Swaraj flag. It was again a tricolour (red, green and white) and had a spinning wheel in the centre, representing the Gandhian ideal of self-help. Carrying the flag, holding it aloft, during marches became a symbol of defiance.
