AGHAṚ SIṄGH (d. 1764) was, according to Giānī Giān Siṅgh, Panth Prakāsh, one of the seven sons of Bhāī Nagāhīā, a Dullaṭ Jaṭṭ of Lauṅgovāl, in present-day Saṅgrūr district of the Punjab. He received amrit, the Khālsā rites of initiation, from his uncle Bhāī Manī Siṅgh, then high priest of the Harimandar at Amritsar. He, along with his brother Tharāj Siṅgh, fought against the Mughals in Amritsar and avenged the execution of Bhāī Manī Siṅgh by slaying his tormentors. He also confronted and killed Mīr Momin Khān of Kasūr who, after the death in November 1753 of Mīr Mannū, the governor of the Punjab, had launched a renewed campaign of persecution against the Sikhs.
Aghaṛ Siṅgh died in January 1764 at Sirhind fighting against the provincial governor, Zain Khān.
