After the Landtag election of 1930, Brunswick became the second state in Germany where the Nazis participated in government, when the National Socialist German Workers' Party (NSDAP) formed a coalition government with several conservative and right-wing parties. With the support of Dietrich Klagges, Brunswick's minister of the interior, the NSDAP organized a large SA rally in Braunschweig. On 17–18 October 1931, 100,000 SA stormtroopers marched through the city, street fights between Nazis, socialists, and communists left several dead or injured. On 25 February 1932, the state of Brunswick granted Adolf Hitler German citizenship to allow him to run in the 1932 German presidential election. In Braunschweig, Nazis carried out several attacks on political enemies, with the acquiescence of the state government.
