French syndicat `trade union'. political movement that rejected parliamentary activity in favour of direct action, culminating in a revolutionary general strike to secure worker ownership and control of industry. The idea originated under Robert Owen's influence in the 1830s, acquired its name and its more violent aspects in France from the philosopher Sorel, and also reached the USA (see Industrial Workers of the World). After 1918 syndicalism was absorbed in communism, although it continued to have an independent existence in Spain until the late 1930s.
