The diaries of Erich Mühsam offer a unique insight into the life of one of the most significant German anarchists. Over a period of 15 years, from 1910 to 1924, Mühsam documents his thoughts, experiences, and political beliefs in a stylistically concise and honest writing style. These records are not only a personal document but also a historical testimony of a time of upheaval and revolution. Mühsam lived anarchy as a practical concept and opposed societal conventions. His diaries are permeated with the expectation of change, which he actively helped shape, particularly during the Munich Soviet Revolution. This edition, published in 15 volumes, is complemented by an online edition that provides additional materials and explanations to deepen the understanding of the historical contexts. The meticulously edited texts are a valuable resource for anyone interested in history, politics, and literature.
