The 1925 Baden state election was held on 25 October 1925 to elect the 72 members of the Landtag of the Republic of Baden.[1]
Minister of the Interior Adam Remmele lifted the ban on the Nazi Party in 1925, stating that they were political irrelevant. Robert Heinrich Wagner was appointed as the Nazi Gauleiter of Gau Baden, the only person to hold that position, on 25 March 1925, and served until 1945.
Baden was 58.5% Catholic, 38.7% Protestant, and 2.9% were members of another religion. The Centre Party and Social Democratic Party (SPD) placed first and second respectively in Baden in the 1928 federal election.
The German National People's Party (DNVP) and Agricultural League formed a right-wing Rechtsblock coalition.
