Broch wrote his trilogy The Sleepwalkers between 1928 and 1932. In three novels, he vivisected and analyzed the era of Wilhelm II who reigned from 1888 to 1918. His works impress not only with the realism of the account but also with the subtle psychological portrayal of protagonists. Broch himself described his creative process as “extended naturalism” – he described the intertwined rational and irrational planes of physical experience and used them exemplary on representatives of various social classes within the Wilhelminism.
Die Schlafwandler (title of the English translation: The Sleepwalkers) by Hermann Broch has been translated to Bulgarian (excerpt) by Ljubomir Iliev under the title Сомнамбулите, published by Altera, Sofia.
