Namasudra

Namasudra (Bengali: নমঃশূদ্র), earlier known as Chandal, is an Avarna Bengali Hindu community originating from eastern and central Bengal. The term Chandal or Chandala is usually considered as a slur. They were traditionally engaged in fishing and as boatmen, and later in cultivation. They lived outside the four-tier ritual varna system and thus were outcastes.
