Input: Question: How many people died in the war that caused Constandse to develop anti-militarist ideas? Passage:The son of a baptist hotelier, Constandse completed the normal school between 1914 and 1918 and in this period came into contact with the teetotalers movement. In response to World War I, he developed anti-militarist ideas. He joined the Social-Anarchist Youth Organisation (Dutch Sociaal-Anarchistische Jeugd Organisatie, SAJO) in 1919. Within this organisation, he chose the side of the individualist faction within this organisation when factional struggles erupted, denouncing even trade organizations as counterrevolutionary. Instead of taking a job as a teacher, Constandse devoted himself to spreading anarchist ideas. He published two anarchist monthlies, Alarm (1922–1926) and Opstand ("Revolt", 1926–1928), which together with Herman Schuurman's De Moker and Arthur Lehning's Grondslagen renewed the theoretical basis of Dutch anarchism. Constandse's 1927 call for mutiny in De Vrije Socialist ("the free socialist"), following the sending of HNLMS Sumatra to Shanghai, led to a conviction for sedition and a prison sentence of two months.
