How did the Social Democratic Party continue participating in elections while it was outlawed?
Under the Anti-Socialist Law enacted in 1878, the Social Democratic Party was officially declared illegal, and its meetings and the distribution of its literature were prohibited by the government of Otto von Bismarck.12
Despite these restrictions, the party continued to operate effectively in practice. The laws did not prevent Social Democrats from running as candidates in elections, and they continued to hold seats in the Reichstag. Furthermore, the party maintained its influence by smuggling socialist journals into the country from Switzerland.2
Ultimately, the repression proved ineffective at curbing the movement's growth. By the time the law expired in 1890, the party had significantly increased its support, demonstrating that the strategy of education and political participation—rather than conspiracy—had been successful.31
