In page Clara Zetkin:

"

Having studied to become a teacher, Zetkin developed connections with the women's movement and the labour movement in Germany from 1874. In 1878 she joined the Socialist Workers' Party (Sozialistische Arbeiterpartei, SAP). This party had been founded in 1875 by merging two previous parties: the ADAV formed by Ferdinand Lassalle and the SDAP of August Bebel and Wilhelm Liebknecht. In 1890, its name was changed to its modern version Social Democratic Party of Germany (SPD).[citation needed]
