With What Congress and Gandhi Have Done to the Untouchables, Ambedkar intensified his attacks on Gandhi and the Congress, charging them with hypocrisy. In his work Who Were the Shudras,Ambedkar attempted to explain the formation of the Shudras i.e. the lowest caste in hierarchy of Hindu caste system.

The Congress decided to boycott the Commission and drafted its own version of a constitution for free India. The Congress version had no provisions for the depressed classes. Ambedkar became more skeptical of the Congress's commitment to safeguard the rights of the depressed classes.
