Early beginnings
Feldmann joined the SPD in 1974. From 1981, he took an active part in university politics as chair of the General Students' Committee, or AStA, at Marburg university. In the same year he was also elected vice president of the SPD youth organization Young Socialists in the SPD, or Jusos, in the German State of Hesse. He joined the Frankfurt city council in 1988 and was elected vice president of his party's parliamentary group in 2004.
In 2007, Feldmann – together with Sergey Lagodinsky – was a co-founder of the Arbeitskreis jüdischer Sozialdemokratinnen und Sozialdemokraten, or AJS, a committee of Jewish members within the SPD.[4][5][6] Feldmann has described himself as a "liberal Jew", but says his beliefs are a private matter.[7][8]
Mayor of Frankfurt, 2012–2022
In a ballot on 25 March 2012, Feldmann was elected mayor of Frankfurt, gaining 57.4 percent of the votes cast against his competitor Boris Rhein (CDU) who came out second with 42.6 percent.[9] Feldmann was successful with an election programme putting social aspects such as affordable housing on top of the agenda. Mr Feldmann "is also a strong advocate of Israel’s security", the Jerusalem Post noted.[3] He is the first German-Jewish politician to be elected mayor of Frankfurt since Ludwig Landmann who was expelled from his office in 1933.[3][10] He was the first Jewish politician to be directly elected mayor of any major city in Germany since World War II,[8][11] and second overall to Herbert Weichmann (SPD) who was indirectly elected mayor of Hamburg in 1965.
In 2019, Feldmann's wife Zübeyde was found to be being paid above her pay grade by her employer, the Arbeiterwohlfahrt (AWO) welfare organization, and to have been given use of a company car. The city prosecutor opened an investigation into whether Peter Feldmann, also formerly an employee of AWO, had influenced his wife's compensation.[12]
After the football club Eintracht Frankfurt won the 2021–22 UEFA Europa League on 18 May 2022, Feldmann was severely criticized for several acts at the celebration, including making a sexist statement about air stewardesses, barring club board members from the Römer city hall, and snatching the UEFA Cup trophy from the team captain and coach. The Frankfurt SPD withdrew their support of Feldmann and urged him to resign. On 25 May 2022, Feldmann announced that he would not resign, but would withdraw from duties until the summer break.[13] Feldmann faced a recall election on 6 November 2022, after announcing and subsequently withdrawing his resignation.[14]
Feldmann lost the recall election, with 95% of votes against him and the turnout threshold of 30% reached. He left office on 11 November 2022.[15]
Post-mayoral career
On 23 December 2022, Feldmann was found guilty of two counts of accepting a benefit and fined 21,000 euros. Feldmann announced he would appeal the verdict.[16]
Feldmann left the SPD in February 2023. In October 2023, Feldmann announced that he had joined The Left and would work with the party on projects in Wetteraukreis. The national leadership of The Left denied that he was a member, noting that there were reservations within the party about accepting him. Feldmann later agreed not to pursue his application to join.[17]
