Artur Sirk joined the Estonian Demobilised Soldiers League upon its formation in 1921 which led to him starting the Vaps Movement, which mirrored many of the characteristics of the fascist movement.
Sirk joined Eesti Demobiliseeritud Sojavaelaste Liit (Estonian Demobilised Soldiers League) upon its formation in 1921 and its successor movement, Eesti Vabadussojalaste Liit (Union of Participants in the Estonian War of Independence), being appointed deputy chairman of the latter group at its inaugural general meeting on 10 October 1926. Vaps adopted an increasingly paramilitary style that mirrored many of the characteristics of the fascist movements growing elsewhere in Europe and Sirk, who was talented orator and charismatic demagogue, was soon recognised as the movement's driving force.
