社会主義者鎮圧法
This political activism placed Grottkau in the sights of the German police. Faced with arrest by the authorities under the Anti-Socialist Laws, Grottkau emigrated to the United States of America in 1878. A talented writer and orator, Grottkau found his way to the German émigré community in Chicago, where he immediately landed a job on the staff of the Social Democratic "Chicagoer Arbeiter-Zeitung" (Chicago Workers' News).
