On 9 November 1989, border crossings in Berlin opened and the Berlin Wall effectively fell. The sudden freedom to travel intensified pressure on the GDR’s planned economy, as people compared living standards directly and many began moving west. Economic reform quickly became inseparable from political change.
On 7 December 1989, the Central Round Table first convened in East Berlin, bringing together government-linked groups and opposition movements. It helped set the rules for a peaceful transition and debated how to reform the GDR’s political and economic system. As public opinion shifted, the discussions increasingly pointed toward rapid unification with West Germany.
On 13 February 1990, the “Two Plus Four” process began, involving the two German states and the four WWII occupying powers (US, UK, France, USSR). These talks were crucial because reunification required international agreement on borders, security, and sovereignty. The negotiations set the diplomatic framework that made economic and political unification possible.
On 18 March 1990, East Germany held its first free parliamentary election. Parties favoring quick reunification won, giving the new government a strong mandate to replace the planned economy with a market-based system. This vote shifted the transition from gradual reform toward fast institutional merger with West Germany.
On 18 May 1990, the two German states signed a treaty creating a Monetary, Economic and Social Union. It laid out how East Germany would adopt West Germany’s currency and key economic and social rules. This was a turning point because it moved the GDR from central planning toward market institutions on a fixed timetable.
On 17 June 1990, the Volkskammer passed the Treuhand law, creating the Treuhandanstalt to reorganize and privatize GDR state-owned enterprises. The goal was to shift “people’s property” into competitive companies in a market economy. This decision shaped the later economic shock of closures, sales, and job losses across the former GDR.
On 1 July 1990, the Monetary, Economic and Social Union took effect and the Deutsche Mark became legal tender in East Germany. The currency changeover quickly connected East German wages, savings, and prices to West German monetary policy. It also exposed many East German firms—built for a planned economy—to immediate market competition.
On 31 August 1990, East and West Germany signed the Unification Treaty, which set the terms for the GDR to accede to the Federal Republic. It established how laws and institutions would be extended to the new eastern Länder (states). With this treaty, economic transition became a legal and administrative merger, not just a policy goal.
On 12 September 1990, the Treaty on the Final Settlement with Respect to Germany (Two Plus Four Treaty) was signed. It cleared the way for reunification by settling key external issues, including the end of Allied rights in Germany and Berlin. This international agreement reduced uncertainty for investors and institutions during the economic transition.
On 3 October 1990, the GDR ceased to exist and joined the Federal Republic of Germany. East Germany’s economy was now fully under West German legal, fiscal, and regulatory systems, with major restructuring channeled through institutions like the Treuhandanstalt. Reunification marked the formal end of the socialist planned economy in East Germany.
On 14 November 1990, Germany and Poland signed a treaty confirming their shared border along the Oder–Neisse line. The agreement helped stabilize the post-reunification settlement by reducing a major regional dispute. Clear borders supported the new Germany’s international acceptance and the secure environment needed for long-term economic integration.
On 15 March 1991, the Two Plus Four Treaty entered into force, and unified Germany became fully sovereign as the Four Powers’ remaining rights ended. This closed the core legal chapter of reunification and reinforced Germany’s authority to make independent economic and security policy. By this point, the East German transition had moved from emergency change to long-term restructuring within a single German state.
