Why did gandhiji start dandi march?

Gandhiji started the Dandi March in 1930 as a nonviolent protest against the British salt tax, which he viewed as an unjust law that exploited the Indian populace. The march symbolized resistance to British rule and aimed to mobilize Indian citizens to defy the salt tax by making their own salt from seawater. This act of civil disobedience was intended to inspire nationwide participation in the struggle for independence and to highlight the broader issues of colonial oppression.
