The doctor of law Ludwig Marum joined the SPD at a young age and took on socially underprivileged clients after opening a law practice in Karlsruhe in 1908. From 1911 to 1921, he was a municipal councilor in Karlsruhe and in 1914 became a member of the Baden state parliament for the SPD. After the 1918 November Revolution, Marum was appointed to the provisional state government as justice minister. He was chairman of the SPD parliamentary group in the Republic of Baden from 1919 to 1928. He was particularly involved in legal policy, advocating the abolition of the death penalty and rights for illegitimate children, opposing discrimination against unmarried mothers, and supporting equal pay for men and women. During the final phase of the Weimar Republic, he took a clear stand against the rising National Socialist movement. Particularly in the 1933 Reichstag election campaign, he made public attacks on Hitler and the National Socialists’ policies. He was involved in a number of legal disputes with National Socialists. Due to his active resistance against the NSDAP, Marum was taken into “protective custody” in the Karlsruhe local prison on March 10, 1933. On May 16, 1933, he and six other leading Social Democrats from Baden were transferred to the newly established Kislau concentration camp near Bruchsal, in a planned campaign carried out under humiliating circumstances. Ludwig Marum was murdered there on March 29, 1934.
