Most of them are from Maharashtra state, but some have come from as far away as the northern state of Uttar Pradesh. Many have been living in Mumbai's Shivaji Park for days.

Huge tents were erected for the visitors to sleep in and temporary bathrooms constructed for their use. Free food was also provided by some organisations.

Tight security arrangements were made to ensure that the event passes off peacefully. Many police were deployed and paramilitary soldiers are on standby.

Prayers are held at the memorial built in honour of Dr Ambedkar. Born a Dalit, he converted to Buddhism.

Fifty years after his death, Dr Ambedkar enjoys iconic status among the Dalits. His pictures are bought by many who keep them alongside that of the Buddha.

Babasaheb Athavale is a social worker. He says Dalits are still discriminated against. "During marriages, we are served food separately. The higher caste people don't eat with us."

Baby Ramesh Gade is from Bhusawal, in Maharashtra. "Babasaheb is our God, he did a lot for us. And this is one time we can come to Mumbai and have a holiday," she says

Siddharth Namdeo Chourpagar is pursuing a Masters degree in Political Science. "Babasaheb told us to educate ourselves and fight for our rights. This is my goal too."
