In June 2009, for the first time the Greens gained the most seats in a German city with more than 500,000 inhabitants, effectively changing the balance of power in the city council. For the first time since 1972 the CDU no longer held the most seats, toppling its absolute majority shared with the Independent Party and the FDP. According to the German newspaper Die Welt, the main reason for the Greens' victory was disgruntlement with the controversial Stuttgart 21 rail project.
