The Italian anarchist Errico Malatesta (1853-1932) is one of the most prominent figures of the anarchist movement. He was active in many countries in Europe (Italy, Switzerland, Spain, France, England), in North America (USA), and in South America (Argentina), and essentially continued the work of Bakunin. During his stay in England, he also collaborated with Kropotkin.

The book includes:
a) Malatesta's biography by the historian of anarchism Max Nettlau.
b) Malatesta's main texts, in which he outlines the content of anarchism and the means to achieve it, studies the issue of organization, and also expresses his views on everyday problems (love and romance, cocaine, etc.). His two texts on Kropotkin are also significant.
