Last year, the Osteuropa-Institut celebrated the seventieth anniversary of its founding in 1951. For the first time, the anniversary exhibition "70 Years of the OEI" dealt with a wide-ranging review of the history of the Osteuropa-Institut, reflecting Berlin's and Germany's eventful relations with its eastern neighbors. Highlights were cast on the Institute's confrontation with National Socialism as well as on its development at the time of the student protests and the years of system collapse and system transformation since the 1990s. The exhibition was designed as a joint project of the work areas, the students and the secretaries of the OEI. After a festive event for the opening of the exhibition on 01.11.2021, the exhibition banners were on display in the winter semester 2021/22 in the Henry Ford Building and in the Silberlaube of the FU. Since the beginning of February, selected parts of the exhibition have been presented in the institute foyer at Garystraße 55 during the regular opening hours of the OEI (Mon-Fri from 8am-8pm).
