Caste as a factor in Bihar politics

Caste: The Prime Factor

In Bihar, the electorate may be classified on the basis of caste, religion, class, etc., but caste considerations are of prime importance.

1977The turning point

Though the backward castes make up nearly 60% of Bihar’s electorate, until the early 1970s these castes were not politically significant. 1977 was the turning point in their political organisation, when reservation for the backward castes in government service was introduced.
