Thousands of soldiers have been deployed to Haryana state in northern India where protesters have been killed in riots.
Jats - a traditionally rural community of farmers - are demanding more government jobs and places in state-run universities.
They complain of discrimination because of India's caste system, not because they are from a lower caste but from a higher one.
The Jats say they are being shut out because of a quota system that gives more opportunities to Indians from lower castes.
Why are they demanding more opportunities? And what are the roots of the caste system?
