The Siuru literary movement, named after a fire-bird in Finno-Ugrian mythology, was founded in 1917 in Estonia. It was an expressionistic and neo-romantic movement that ran counter to the Young Estonia formalist tradition.
Along with the founder August Gailit, the movement included the following young poets and writers: Marie Under, Henrik Visnapuu, Johannes Semper, Friedebert Tuglas and Artur Adson. Between 1917 and 1919, Siuru published three volumes of poetry. 1919 led to conflicts within the group. Visnapuu and Gailit left, while Johannes Barbarus and August Alle joined as new members.
The members of Siuru had an affinity with futurism and Impressionism. Their poetry was often seen as scandalous due to their erotic nature. Siuru's philosophy stressed the freedom of the human spirit. Mottos of the group included Carpe diem!, and May the joy of creation be our only moving force, the latter suggested by Friedebert Tuglas. The group's symbol was white chrysanthemum.
A major result of Siuru's activities was popularisation of literature among Estonian people, leading to the active development of original Estonian literature in the young Republic of Estonia. While the movement itself was short-lived, cut short by Estonian independence and the ensuing movement of national literature, its members rose to be major figures in Estonian literature through Estonia's first period of independence and in the exile Estonian literary community during Soviet occupation.
