German unification — formally the accession of the German Democratic Republic to the Federal Republic of Germany under Article 23 of the West German Basic Law — took effect at midnight between the 2nd and 3rd of October 1990. The constitutional act was straightforward: the five recreated East German Länder (Brandenburg, Mecklenburg-Vorpommern, Saxony, Saxony-Anhalt, Thuringia, plus the merged East and West Berlin) joined the existing federal structure. The legal, economic, and social transition was anything but straightforward. It is still, in 2026, not fully complete.
The Treaty on the Establishment of a Currency, Economic and Social Union, signed in May 1990, had already converted the East German economy to the Deutsche Mark on the 1st of July 1990 — three months before formal political union. The conversion was conducted at a rate of 1:1 for wages, pensions, and small savings, and 1:2 for larger holdings. The decision to convert at parity rather than at the realistic market rate of around 4:1 was political, intended to prevent a mass migration of East Germans westward. It had the unintended effect of pricing East German industry out of its own markets overnight. Wages were now Western; productivity was still Eastern. Enterprises that had been competitive within the Soviet bloc became unviable within six weeks.
The Treuhand
The institution responsible for managing the transition of East German state-owned enterprises to private ownership was the Treuhandanstalt — the Trust Agency. Established in March 1990 by the last East German government as an instrument for converting the country's 8,000 state-owned firms into private companies, the Treuhand inherited responsibility for around four million employees. Its first president, Detlev Karsten Rohwedder, a respected West German businessman, was assassinated in April 1991 by the Red Army Faction. His successor, Birgit Breuel, oversaw the bulk of the sell-off until 1994.
The results were politically catastrophic for East Germans. Around 3.8 million East German jobs were lost between 1990 and 1994 — about half the entire workforce. Most were lost in heavy industry, agriculture, and the bloated administrative bureaucracy. Enterprises were sold, where possible, to West German firms; many were sold cheaply because of the speed of the process and the fragility of their post-currency-union balance sheets. Others were shut down outright. The Treuhand was, by 1994, the largest holder of property in Europe and the most-hated institution in the new federal states. The unemployment rate in the eastern Länder peaked at around 20% in 1997 and remained above the Western rate for the next twenty years.
The wall, demolished
The physical infrastructure of the GDR was, in many places, simply removed. The Berlin Wall was largely demolished within eighteen months of its fall — partly by official decision, partly by souvenir-hunters. Around 200 metres of it survive in original sections at the East Side Gallery on the Mühlenstraße, at the Berlin Wall Memorial on Bernauer Straße, at the Checkpoint Charlie museum, and in smaller fragments. The death strip, where it ran through central Berlin, was reused as the broad avenue of new federal government buildings (the area from the Brandenburg Gate to Potsdamer Platz).
The Palace of the Republic — the modernist 1976 building that had housed the East German parliament and served as a cultural venue — was found to contain dangerous quantities of asbestos. It was closed in 1990 and gradually dismantled between 2006 and 2008. In its place, between 2013 and 2020, the Berlin Stadtschloss (City Palace) was rebuilt as a partial reconstruction of the Hohenzollern royal palace that had stood on the site until its demolition by the GDR in 1950. The replacement is now the Humboldt Forum, a museum complex. The decision to remove the Palace of the Republic — the most physically prominent surviving GDR-era building in central Berlin — was politically contested at the time and remains so.
Ostalgie
One unexpected cultural phenomenon of the post-unification period was Ostalgie — nostalgia for the GDR. It emerged in the mid-1990s, became commercially significant around the 25th anniversary of the wall's fall, and has persisted, in modified form, into the 2020s. Ostalgie is partly a market phenomenon: the production of GDR-branded products (Spreewald gherkins, Vita Cola, Florena cosmetics, Rotkäppchen sparkling wine) marketed both to East Germans nostalgic for their childhoods and to West Germans intrigued by the artifacts of a lost civilisation. The 2003 film Good Bye, Lenin! — set in late 1989 East Berlin — is the cultural high point of the phenomenon.
Ostalgie is also, more seriously, a political phenomenon. East Germans, surveyed throughout the post-1990 decades, have consistently reported lower satisfaction with unified Germany than West Germans; have voted at higher rates for non-mainstream parties (initially the post-Communist PDS and its successor Die Linke, more recently the right-populist AfD); and have continued to identify, in significant minorities, as East rather than as German. The post-Communist party Die Linke held the premiership of Thuringia from 2014 to 2024. The far-right AfD became, in 2024, the largest party in two of the five new federal states.
The Stasi files
The most distinctive institutional inheritance of the GDR is the Stasi Records Agency — the BStU (Bundesbeauftragte für die Stasi-Unterlagen), established by federal law in 1991. The agency took custody of the Stasi archives (six million dossiers, plus around 15,000 sacks of shredded documents that the Stasi had been unable to fully destroy in November 1989) and made them available to former targets. Any East German citizen, on application, could read their own file. They could also, in many cases, identify the informants who had reported on them.
The opening of the Stasi files has been the most significant exercise of post-totalitarian justice in European history. About three million applications have been filed since 1992; about 1.7 million have been granted access to personal files. The political and emotional impact has been considerable. Marriages have ended on the discovery that a spouse had been an IM. Friendships have ended on the discovery of betrayal. Career politicians have been exposed and forced from public life. The BStU was incorporated into the Federal Archives in 2021; the files remain accessible.
What remains
Thirty-five years after unification, the territory of the former GDR is, in many ways, recognisably part of unified Germany. The infrastructure is rebuilt. The cities — Leipzig in particular — have flourished. The major industries have been reorganised. The roads are equivalent to those in the west. The cultural institutions (the Berlin and Dresden museums, the Leipzig book fair, the Bayreuth festival in Bavaria but with substantial east German visitation) are integrated.
But the territory is also still, in distinctive ways, eastern. Median household incomes are still about 85% of the western average. Birth rates were significantly lower in the 1990s, producing a demographic hollow that is still visible in age pyramids. Internal migration has been one-directional: about 1.5 million people have moved from east to west since 1990, with much smaller flows in the other direction. The eastern Länder have higher unemployment, lower productivity, and an older population than the western ones. The far-right AfD has institutionalised an east-versus-west political polarisation that is, in 2026, one of the defining facts of German politics.
The country called the German Democratic Republic, in any case, has been gone for thirty-five years. The country called the Federal Republic of Germany absorbed it. What lives on is the territory, the population, and a substantial cultural inheritance — some of it nostalgic, some of it political, some of it the slowly fading institutional and architectural archaeology of forty-one years of state socialism on the eastern side of an old line.
