"Jats in Haryana will launch an agitation next month. It will be peaceful," All India Jat Aarkshan Sangarsh Samiti Haryana president Hawa Singh Sangwan said.
The previous Hooda government had in 2013 accorded special backward class status to Jats. However, the decision was stayed by the Punjab and Haryana High Court last month.
Sangwan criticised the police action against protesters in parts of Gujarat, saying that "everyone has the right to fight for justice in a democracy".
"If Jats did not get their right, they will intensify their agitation in future," he warned.
"We (Jats) don't indulge in agitation, but if we are not given our due, we never sit silent," Sangwan said.
Jats in Haryana are also in touch with people from other communities, including Rors and have formed 'brigades' for the proposed agitation.
