B.R. Ambedkar belongs to the Mahar caste.

The Mahar caste is a Dalit community in India, historically considered to be the lowest in the caste hierarchy. The caste system in India is a social structure that categorizes individuals into different groups based on their birth and occupation. The Mahars were traditionally engaged in occupations such as cleaning, tanning, and handling dead animals, which were considered "polluting" by the higher castes.

B.R. Ambedkar, born on April 14, 1891, was an Indian jurist, economist, politician, and social reformer who dedicated his life to fighting against caste discrimination and advocating for the rights of the Dalit community. Ambedkar himself belonged to the Mahar caste and faced discrimination and social exclusion throughout his life.

Ambedkar played a pivotal role in drafting the Indian Constitution and was the chief architect of the Constitution of India. He fought for the rights of the Dalits and other marginalized communities, advocating for social equality, education, and political representation. Ambedkar also played a significant role in the Dalit Buddhist movement and converted to Buddhism along with millions of his followers.

Ambedkar's contributions to the upliftment of the Dalit community and his fight against social injustice have earned him immense respect and recognition. He is often referred to as the "Father of the Indian Constitution" and is considered one of the most influential figures in modern Indian history.

Ambedkar's legacy continues to inspire and guide the Dalit community in their struggle for equality and social justice. His efforts towards eradicating caste discrimination and empowering the marginalized sections of society have left a lasting impact on India's socio-political landscape.
