No violence could stop the growth of the BJP in Bengal, he said.
"Today, I met the family members of the victims of political violence in Bengal in the last six months... All this happened because they did not support the ideology of the ruling Trinamool Congress," Mr Shah told reporters on the last day of his three-day visit to Bengal.
"I want to ask the people here -- is this Rabindranath Tagore's Bengal? Is this Swami Vivekananda's Bengal? No one has the freedom to play a part in any political party other than the TMC," he said.
This kind of violence was perhaps not seen anywhere else, the BJP president said.
The BJP chief said development could not take place in Bengal under such circumstances.
He urged human rights organisations to report political violence against BJP workers in the state.
Members of human rights organisations should visit Basirhat, Birbhum and other places in the state and talk to the victims of political violence, he said.
