"Ostberlin. Clara-Zetkin-Str. Mai 1960"
Berlin, May 1960. This slogan refers to Krushchev's so-called "Berlin memorandum" from
1958. In it, he demanded that the Western allies give up their military presence in West
Berlin within six months and leave West Berlin as a "Free and de-militarized city".
Otherwise, he threatened to conclude a separate peace treaty with the GDR which would
have given the East German leadership sovereign control over access routes to West Berlin,
regardless of Allied agreements. The memorandum led to the so-called "Second Berlin crisis",
which went on for a few years and culminated in the erection of the Wall in 1961 (see also
„The Wall“). The East German leadership was keen to support the Soviet initiative, as any
chance for increased state sovereignty was welcome to them. The slogan reads: "West Berlin
will be a free city".
