The Namdharis are a Amritdhari sect of Sikhism. Namdharis are also known as Kuka Sikhs or Sant Khalsa (Saint Khalsa). The Namdharis are recognized as freedom fighters due to their attacks on cow slaughterers. As a result, some Sikhs were sentenced to death by hanging at Ram Bagh, Amritsar. A group of 66 Namdhari Sikhs were blown up by cannons on 17th -18th Jan, 1872 for protesting against the British and one 12-year-old boy (Bishan Singh) was beheaded (martyred) by sword on the same day in MalerKotla.
