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.
As West Germany was reorganised and gained independence from its occupiers, the German Democratic Republic was established in East Germany in 1949. The creation of the two states solidified the 1945 division of Germany.  On 10 March 1952, (in what would become known as the " Stalin Note ") Stalin put forth a proposal to reunify Germany with a policy of neutrality, with no conditions on economic policies and with guarantees for "the rights of man and basic freedoms, including freedom of speech, press, religious persuasion, political conviction, and assembly" and free activity of democratic parties and organizations.  This was turned down; reunification was not a priority for the leadership of West Germany, and the NATO powers declined the proposal, asserting that Germany should be able to join NATO and that such a negotiation with the Soviet Union would be seen as a capitulation. There have been several debates about whether a real chance for reunification had been missed in 1952.
Recent studies produced by historians Christian Booß and Helmut Müller-Enbergs also show domestic surveillance in East Germany went far beyond the Stasi's network of IMs. The two work at the BStU and not long ago, they happened across Stasi informant groups into which hardly any research has been conducted. They found that institutions in which people provided information about others were categorized as POZW -- which stood for "Partner in Political-Operative Cooperation." In contrast to IMs feeding information to the Stasi, these people were not forced to sign a document obliging them to pass along information. But they did so nonetheless. Numerous POZW reports are still in existence -- from banks, for example, or libraries, hospitals, registration offices and judiciary agencies.
