On May 22, 1963, right-wing forces ran down and killed Grigoris Lambrakis, a leftist member of the Parliament, who had been speaking at a peace meeting. Vassilis Vassilikos based his novel Z on Lambrakis's death; Costa-Gavras then adapted the novel for his film starring Yves Montand. Lambrakis's assassination and the protests that followed were part of a long series of events culminating in the dictatorship of the colonels in the late 1960s. The bronze monument shows a figure with arms upraised, flanked by a dove of peace.
