The making of the Free State of Thuringia

A region is not yet a state

For centuries, Thuringia named a historical and cultural region without identifying one government over today’s territory. Dynastic partitions, small principalities and Prussian districts produced overlapping loyalties and discontinuous borders. The constitutional traditions of the individual territories mattered, but their assemblies were not modern parliaments elected by all adults. This distinction prevents an attractive regional identity from being mistaken for continuous statehood. 1

The formation of today’s Land is therefore best followed through specific institutional breaks. The regional overview introduces the Wartburg and Weimar; this chapter follows the political decisions that made a state.

1918–1919: from monarchies to republics

The November Revolution of 1918 ended the rule of the Thuringian princes. Elections in 1919 gave the successor states new representative institutions. A common Thuringian state was one possible response to fragmentation, not a result already settled by geography. Negotiations had to reconcile administrations, finances and political interests. 1

The word Freistaat, literally “free state”, belongs to this republican break with monarchy. It does not confer greater sovereignty than other German Länder. The name used today recalls a democratic tradition rather than a separate category of federal membership. 1 7

1920: seven states unite, Erfurt stays outside

The seven constituent states were Sachsen-Weimar-Eisenach, Sachsen-Meiningen, Sachsen-Altenburg, Sachsen-Gotha, Schwarzburg-Rudolstadt, Schwarzburg-Sondershausen and the Volksstaat Reuß. The latter already united the two former Reuß principalities. The merger took effect on 1 May 1920. Weimar became the capital. Coburg joined Bavaria instead; Prussia did not contribute its Thuringian territories. Erfurt consequently remained outside the new Land. 1 2

This is a central distinction for an Erfurt history: a city could be culturally Thuringian while legally Prussian. The 1920 state was not identical in territory to the federal state established in 1990.

1921–1932: a democratic beginning under pressure

The constitution of 11 March 1921 organised the new republic. Yet constitutional rules did not by themselves secure stable majorities or acceptance of parliamentary government. The Landtag’s historical account describes frequent government crises and elections. In January 1930 the NSDAP entered a German state government here for the first time; in 1932 it formed a government led by Fritz Sauckel. 3

These events matter because the destruction of democracy had a local prehistory before Hitler’s appointment as Reich chancellor. It should not be reduced to an administrative change arriving from Berlin in 1933.

1933–1934: state institutions without self-government

Nazi Gleichschaltung dismantled parliamentary democracy and federal independence. The continued use of a regional name did not mean the survival of accountable government. The constitutional court’s history distinguishes the existence of institutions on paper from the loss of their effective constitutional functions. 4

The war and dictatorship chapter follows persecution and responsibility in Erfurt itself. Here the issue is how a regional democratic order was stripped of substance.

1945–1946: a larger Land, a constrained constitution

After the war, the former Prussian administrative district of Erfurt and the district of Schmalkalden were joined to Thuringia. This brought Erfurt within the Land and changed the geographical basis of statehood. It was a post-war reorganisation, not the delayed implementation of the 1920 merger. 3

A new constitution was adopted in December 1946. The Soviet occupation and the growing power of the SED constrained political pluralism. The presence of rights in a constitutional document must therefore be considered alongside the actual conditions under which institutions operated. 4

1952: districts replace functioning Länder

The GDR’s centralisation replaced effective Land structures with the districts of Erfurt, Gera and Suhl in 1952. Regional identity persisted without a functioning federal state government. A district administration belonged to a centrally organised political system; it was not equivalent to the government of a Land in the Federal Republic. 4

The GDR and Stasi chapter examines the consequences through surveillance, detention and the citizens who challenged the dictatorship.

1989–1990: citizens reopen the state question

The Peaceful Revolution ended the SED’s monopoly and made democratic regional institutions possible again. On 15 May 1990, a politically advisory committee for the formation of Thuringia convened in Erfurt. Its work included administration, territorial organisation and a constitution. The Volkskammer adopted the Länder Introduction Act on 22 July 1990. 3

The new state drew mainly on the three GDR districts, with additional border decisions. Historian Steffen Raßloff’s account explains the inclusion of Artern, Altenburg and Schmölln and the conflicting preferences involved. The borders were negotiated; they were not simply copied from 1920 or produced by uniformly favourable local votes. 6

3 October 1990: a federal state of Germany

Article 1 of the Unification Treaty states that Thuringia and the other named eastern Länder became Länder of the Federal Republic on 3 October 1990. That legal date must be distinguished from the July preparatory legislation and the later adoption of a state constitution. 5

The first post-unification Landtag election followed on 14 October. Parliament assembled in Weimar on 25 October 1990; a provisional state statute provided an initial framework. Establishing a parliament, government and administration was work extending beyond the reunification ceremony. 3

1991: why Erfurt became the capital

The capital question remained contested, especially between Erfurt and Weimar. On 10 January 1991, the Landtag chose Erfurt as its seat and state capital. The decision joined Erfurt’s central role to a new democratic institutional identity. It was not the automatic restoration of the capital of the 1920 state, which had been Weimar. 6

1993–1994: a constitution gains democratic approval

Parliamentary drafts, expert advice and public discussion preceded the constitution. The Landtag adopted it at the Wartburg on 25 October 1993. A referendum on 16 October 1994 approved it with 70.13% of votes. Parliamentary adoption and popular confirmation are distinct steps in the constitutional foundation. 3

The constitution’s Article 44 identifies Thuringia as a Land of Germany, a democratic and social state governed by law and committed to protecting the natural foundations of life; it names Erfurt as capital. Articles 45 and 47 describe popular authority and the division of public powers. The legal text is evidence of the constitutional design, not proof that political practice can never depart from it. 7

What the present Free State inherits

Three dates answer different questions: 1920 for the first republican merger, 1990 for today’s federal state, and 1993–1994 for its constitutional settlement. Continuity of regional memory sits alongside discontinuities of territory, regime and institutions.

Sources were checked on 15 October 2026. We distinguish historical scholarship, institutional histories and original constitutional documents; older foundational documents do not become obsolete because their publication year is old. For a much longer timescale, continue to the geological formation of the Thuringian Forest.
