Who was the original leader of Anushilan Samiti?
Anushilan Samiti
By 1902, Calcutta had three secret societies working toward the violent overthrow of British rule in India. One was founded by Calcutta student Satish Chandra Basu with the patronage of Calcutta barrister Pramatha Mitra, another was led by Bengali woman Sarala Devi and the third was founded by Aurobindo Ghosh. Ghosh was one of the strongest proponents of militant Indian nationalism at the time.[5][6] By 1905 the work of Aurobindo and his brother, Barin, enabled Anushilan Samity to spread throughout Bengal. Nationalist writings and publications by Aurobindo and Barin, including Bande Mataram and Jugantar, had a widespread influence on Bengal youth. The 1905 partition of Bengal stimulated radical nationalist sentiments in Bengal's Bhadralok community, helping Anushilan acquire a support base of educated, politically-conscious and disaffected members of local youth societies. Its program emphasized physical training, training its recruits with daggers and lathis (bamboo staffs used as weapons). The Dhaka branch of Anushilan was led by Pulin Behari Das, and branches spread throughout East Bengal and Assam.[7] More than 500 branches were opened in eastern Bengal and Assam, linked by "close and detailed organization" to Pulin's headquarters at Dhaka. It absorbed smaller groups in the province, soon overshadowing its parent organisation in Calcutta. Branches of Dhaka Anushilan emerged in Jessore, Khulna, Faridpur, Rajnagar, Rajendrapur, Mohanpur, Barvali and Bakarganj. Estimates of Dhaka Anushilan Samiti's reach indicate a membership of 15,000 to 20,000. Within two years, Dhaka Anushilan devolved its aims from the Swadeshi to that of political terrorism.[8][9]
Ma Anliang
Ma Anliang fought against the Bai Lang Rebellion, and attacked the Xidaotang () Muslim organization. He was suspicious of the Republicanism of the Xidaotang, since Ma was a conservative and a monarchist and supported Yuan Shikai. Ma arranged for the Xidaotang founder Ma Qixi and his family to be shot dead. Han and Hui soldiers under the Hui generals Ma Anliang and Ma Qi united to fight against Bai Lang's bandit army. 
In 1914, Ma Anliang tried to exterminate the "New New Sect", the Xidaotang and its leader Ma Qixi (his Arabic name was Ersa (Jesus), he was known as "Prophet Jesus" to westerners).
