Urban migration explains why Mahars politicized faster than other Untouchable castes.

Evidence

Over time, a section of the Mahar population left their villages and moved to the city. They worked in the Bombay mills and as casual, unorganised labour in the city. The move widened their horizons and perhaps accounts for why the Mahars were politicised quicker than other Untouchable communities in the region. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 292
