The Free Democratic Party (German: Freie Demokratische Partei, FDP, German pronunciation: [ɛfdeːˈpeː] ) is a liberal political party in Germany. The FDP was founded in 1948 by members of former liberal political parties in Germany before World War II, namely the German Democratic Party and the German People's Party. For most of the second half of the 20th century, particularly from 1961 to 1982, the FDP held the balance of power in the Bundestag. It has been a junior coalition partner to both the CDU/CSU (1949–1956, 1961–1966, 1982–1998, and 2009–2013) and Social Democratic Party (SPD; 1969–1982 and 2021–2024).
In the 2013 federal election, the FDP failed to win any directly elected seats in the Bundestag and came up short of the 5 percent threshold to qualify for list representation, being left without representation in the Bundestag for the first time in its history. In the 2017 federal election, the FDP regained its representation in the Bundestag, receiving 10.6% of the vote. From the 2021 federal election to the 2024 German government crisis, the FDP was part of governing Scholz cabinet in a "traffic light coalition" with the SPD and the Greens. In the 2025 federal election, the party again failed to win any directly elected seats and came up short of the 5 percent threshold to qualify for list representation, leaving the party with no seats in the Bundestag.
