Why was ‘salt’ considered a more effective weapon for protest against Britishers?

(i) Mahatma Gandhi thought that demand to abolish salt tax was a demand which could put a united campaign against the British.

(ii) Salt was something consumed by the rich and poor alike, and it was one of the most essential items of food.

(iii) The tax on salt and the government monopoly over its production, Mahatma Gandhi declared, revealed the most oppressive face of British rule.
