Lorenzo took part in the establishment of sections of the First International in Spain. He was a member of the Spanish Federal Council (1870-72) and was a delegate to the London conference of the First International (1871). During 1872-73, in the ranks of the New Madrid Federation, he opposed the disorganizing activity of the Bakuninists, although his views were close to anarchism (to a considerable degree he was influenced by P. Proudhon). Later Lorenzo participated in the so-called Anarchist International and in a number of anarchosyndicalist publications.
