During his early years of exile he became acquainted with Emma Goldman, and it was partly through her he became an anarchist. With the outbreak of the revolution of 1910, the revolution that he and the P.L.M., more than any other group or person, had paved the way for, Magon devoted the rest of his life to the anarchist cause. Through his influence large areas of land were expropriated by the peasants and worked in common by then under the banner of Tierra y Llbertad, the motto of the P.L.M., later to be adopted by Zapata. During the years of struggle Magon opposed and fought successive so called "revolutionary regimes," resisting both the old and new dictatorships with equal vigour. Imprisoned by the U.S. authorities in 1905, 1907, and 1912 he was finally sentenced to 20 years under the espionage laws in 1918. He died in Leavenworth Prison, Kansas, on November 22, 1922.
