Original sentence: Pirali Brahmin are those Brahmins whose ancestors are said to have eaten with ruling Muslims
Edited sentence: A Pirali Brahmin is any member of a subgrouping of Brahmins found throughout Bengal, which is split between India and Bangladesh.As a result, Brahmin Hindu society shunned the brothers' relatives (who had not converted), and the descendants of these Hindu relatives became known as the Pirali Brahmins — among whom numbered the Tagores.Notably, Rabindranath Tagore and the Tagore family are members of this group.Pir Ali was a Brahmin Hindu convert to Islam; his example resulted in the additional conversion of two Brahmins brothers.The term "Pirali" historically carried a stigmatized and pejorative connotation amongst Brahmins; its eponym is the vizier Mohammad Tahir Pir Ali, who served under a governor of Jessore.This unorthodox background ultimately led the Tagore family to dispense with many of the customs followed by orthodox Brahmins and subsequently they embraced the Brahmo sect of Unitarianism
