フェルディナント・ラッサール
In 1875, the German socialist party (SPD) was founded in Gotha through the merger of two organizations: the Social Democratic Workers' Party, led by August Bebel and Wilhelm Liebknecht, and the General German Workers' Association, founded by Ferdinand Lassalle. A compromise known as the Gotha Program was forged, although it was strongly criticized by Karl Marx for its reformist bias in his "Critique of the Gotha Program".
