This Sunday marks the 25th anniversary of the fall of the Berlin Wall, an event remembered as a symbol of German reunification and a success story for youth-driven revolution everywhere. For nearly 30 years, the wall had been a divisive presence on both sides; the Communist authorities on the Eastern side justified its construction as an Antifaschistischer Schutzwall, or Anti-Fascist Protection Rampart, while West Berlin’s mayor Willy Brandt called it the “Wall of Shame.”
