Traditions, Personalities and Memories: Aspects of Sikh History, 1469–1914, Essays in Honour of Sardar Saran Singh highlights the traditions of self-sacrifice associated with the Sikh gurus and their renowned followers. Ironically, these great traditions ended up being undermined during the most glorious phase of Sikh history—the rule of Maharajah Ranjit Singh—so much so that both the British sympathizers, Chief Khalsa Diwan and the Singh Sabhas, as well as the anti-British Namdharis, tried to revive these noble traditions. Persecuted by the British rulers, the Namdharis sustained their anti-colonial activities through the Ghadar movement in the twentieth century.
