A member of the Catholic party known as
Zentrum, after
World War I Brauns worked towards the establishment of an interdenominational Christian political party which did not materialise. In January 1919, Brauns was elected to the
National Assembly, and in February worked with other delegates to prevent the
Betriebsrätegesetz from reflecting radical
Räte ideology. Brauns was returned to the
Reichstag in June 1920. He joined the cabinet of Chancellor
Constantin Fehrenbach that same month as Minister of Labour, a position he held for the next eight years under changing heads of government. During this time, he worked towards alleviating the differences between the social classes and for a cooperation between the associations of the workers and employers on a footing of equality. This was supposed to be achieved by collective bargaining and work in the '''', a joint institution of labour unions and employers' association. Since 1920, Brauns was a member of the leadership of the
Zentrum where he was part of the party's right wing. This brought him into conflict with the left, since he opposed some of their policies, arguing that getting too close to Social Democratic or Communist positions would remove the reason for existence of the Christian unions and the Zentrum. As Minister of Labour, Brauns advanced laws and decrees on works councils, workers' participation in management, collective bargaining agreements, labour arbitration, labour law and employment exchanges. He also supported rules on policies such as social security entitlements or handouts for the war-wounded. Brauns was a major influence on social policy in Weimar Germany. When
Hermann Müller formed his
second cabinet in 1928, he wanted to retain Brauns as Minister of Labour, but internal party politics in the Zentrum prevented Brauns from staying in office. After leaving the government, Brauns remained a member of the Reichstag, serving first as vice-chair of the
Sozialpolitischer Ausschuss (committee on social policy) and from 1930 to 1933 as its chairman. He also wrote about social policy issues, and was active in the international Catholic labour movement. He led the German delegation to the International Labour Conference at Geneva in 1929–31. In 1931, he chaired a commission named after him, created by chancellor
Heinrich Brüning that looked into the causes and ramifications of the
Great Depression. His connections and frequent travels abroad caused him to be very critical of the Nazi takeover of power in 1933 and made him pessimistic about the path the country was taking. His party did not renominate him for the
Reichstag elections of 5 March 1933 and he retired to
Lindenberg im Allgäu. He was prosecuted by the Nazis and was one of the defendants at the
Volksvereinsprozess (1933–35), where he was found not guilty. Brauns died in Lindenberg on 19 October 1939 following an
appendicitis. ==Honours==
