Berlin border crossings

The Berlin border crossings were border crossings created as a result of the post-World War II division of Germany. Prior to the construction of the Berlin Wall in 1961, travel between the Eastern and Western sectors of Berlin was completely uncontrolled, although restrictions were increasingly introduced by the Soviet and East German authorities at major crossings between the sectors. This free access, especially after the closure of the Inner German border, allowed the Eastern Bloc emigration and defection to occur. East German officials, humiliated by this mass defection, subsequently chose to erect the Berlin Wall in order to prevent residents from leaving East Germany. After the construction of the Berlin Wall in 1961, border stations between East Berlin (regarded as East Germany's capital by the German Democratic Republic but unrecognized by the Western Allies) and the sectors controlled by those three Western Allies were created. Although there were few crossings at first, more sites were built over the wall's lifespan. Many East Germans crossed the wall illegally by climbing over it, sailing around it, or digging under it, while many others died while attempting to cross. Between West Berlin and German Democratic Republic (GDR) territory, the border stations were developed very effectively on the GDR side. (The official designation for controlled border traffic was Grenzübergangsstelle, GÜSt: border crossing site.) Border officials and customs agents would monitor incoming and outgoing traffic according to established procedures, at times with the utmost scrutiny. A strict division of labor among the various organizations was the rule. The security of the outward-facing border and of the border crossings was maintained by special security divisions of the GDR border guard troops (German abbreviation SiK, short for Sicherungskompanien). The actual inspections of vehicle and pedestrian traffic were carried out by the passport control units (German abbreviation PKE, short for Passkontrolleinheiten).
