My book titled Bending Spines: The Propagandas of Nazi Germany and the German Democratic Republic (Michigan State University Press, 2004) provides an analysis of much of the material on the German Propaganda Archive. It can be ordered in the United States through amazon . It is also available in a French translation. A Chinese edition appeared in July 2012 but was almost immediately banned by the Chinese government (but not in Hong Kong). It has since been “unbanned.”
Finally, if you travel Europe and you see two German groups at a campground, you might easily be able to distinguish them. Eastern Germans usually sleep in tents, while western Germans prefer to travel with trailers. We did not find a scientific explanation, but one might posit that it's rooted in western Germans' longer experience traveling the world. Furthermore, many young eastern Germans couldn't even afford a car under communism. Trying to buy a trailer would have been more expensive and nearly impossible for most eastern Germans. While those in the west were able to explore beyond their borders, eastern Germans remained practically imprisoned by their government for nearly 30 years -- until 25 years ago.
Egon Krenz was elected by the politburo to be Honecker's successor. Krenz tried to show that he was looking for change within the GDR but the citizens did not trust him. On November 9, 1989, the SED announced that East Germans would be able to travel to West Berlin the next day. The spokesman who announced the new travel law incorrectly said that it would take effect immediately, implying the Berlin Wall would open that night. People began to gather at border checkpoints at the wall hoping to be let through, but the guards told them that they had no orders to let citizens through. As the number of people grew, the guards became alarmed and tried to contact their superiors but had no responses. Unwilling to use force, the chief guard at the checkpoint relented at 10:54pm and ordered the gate to be opened. Thousands of East-Germans swarmed into West Berlin and the purpose of the wall was deemed now obsolete. The fall of the wall destroyed the SED politically as well as the career of its leader, Egon Krenz. On December 1, 1989, the GDR government revoked the law that guaranteed the SED the right to rule the East German political system, effectively ending communist rule in the GDR.
