ARJAN SIṄGH, BHĀĪ (c. 1906-1924), born to Kishan Siṅgh of the village of Kamālīā, now in Sāhīvāl district of Pakistan, was a zealous worker in the cause of Sikh Gurdwārā reform. As a young boy he was deeply affected by events at Nankāṇā Sāhib in 1921 (See NANKĀṆĀ SĀHIB MASSACRE). Closing down his business he joined the Akālī ranks. He participated in the Gurū kā Bāgh and Jaito agitations : he officiated as one of the Pañj Piāre when the jathā left for Jaito on Baisākh 1, 1981, Bk/12 April 1924. His health deteriorated while he was in police custody and he died on 26 November 1924.
Bhāī Arjan Siṅgh was tall and handsome and led a pious life. He used to compose verses, and one of his poems, "Naukarshāhī nūṅ Chailañj" or Challenge to Bureaucracy, was included in an anthology entitled Shahīdī Khūn. A gurdwārā, a boarding house and a library were erected at Kamālīā to honour his memory.
