“DIESER HÖRSAAL IST BESETZT!” (“This lecture hall is occupied!”) In November and December 2009, signs bearing such slogans were found on doors at over 60 German universities. For the second time that year, a broad student movement managed to gain public attention for its demands. Protests at the University of Vienna kicked off what became a Europe-wide solidarity wave. In Germany, the Viennese protest first triggered occupations in Heidelberg, Münster, and Potsdam, after which students at many other institutions also became involved. In most cases, the biggest or most central lecture halls were taken, and tens of thousands of students marched through the streets.
