Harijans, meaning 'children of God,' is a term coined by Mahatma Gandhi to refer to the community formerly known as 'Untouchables' within the Hindu caste system. This term emerged during the 19th and 20th centuries as part of a broader movement to reform Hindu society by advocating for the rights and dignity of those marginalized under traditional caste structures. Gandhi's use of the term aimed to promote social equality and remove the stigma associated with Untouchability, emphasizing their humanity and contributions to society.
