→ Main article: History of the city of Erfurt
Early history
Traces of the first settlements in the current city area can already be found from prehistoric times. Archaeological finds in the north of Erfurt bear witness to human traces from the Palaeolithic period around 100,000 BC. Further finds in the Erfurt-Melchendorf pit prove settlement in the Neolithic period.
To the west of Erfurt, a large Germanic settlement existed in the centuries AD. It was cut open in 2000 during the construction of the federal motorway 71 and about half of it was excavated between 2001 and 2003 (Erfurt-Frienstedt). For 480, the Germanic collective of the Thuringians (Thuringi) from Hermundurians, Angles and Warns in the Erfurt area has so far been documented by lore, without any archaeological finds being found for the 4th to 10th centuries. From the Roman period, on the other hand, almost 200 coins were found dating back to the 3rd century, as well as 150 Roman pottery fragments and more than 200 fibulae. In addition, there are eleven inhumation graves of the Haßleben-Leuna group.
In the aforementioned Germanic settlement, the Frienstedt site near Erfurt, the oldest Germanic word discovered in central Germany, written in runic script, was found on a comb from a sacrificial shaft: "kaba" (pronounced: kamba; comb).
Medieval
The oldest known documentary mention of Erfurt is found in a letter of Boniface, anno 742 as missionary archbishop to Pope Zacharias II, in which he asks him to confirm the bishops he consecrated and the bishopric seats he established, namely "... the third in the place, (in loco) which is called 'Erphesfurt', which has already been a fortified settlement (urbs) of pagan peasants before times..."
The thus founded bishopric of Erfurt was already united with that of Mainz in 755, when Boniface became archbishop of Mainz. The reasons for this are unclear, possibly the border proximity to the Saxons and Slavs played a role. At the latest with the founding of the bishopric, there must also have been an episcopal church and it can be assumed that this was a precursor church of today's cathedral on the Domberg. In 805 Charlemagne declared Erfurt to be one of the border trading places, not far from the border of the then Frankish Empire. Erfurt had a royal palace under the Carolingians and Ottonians, which is assumed to be safely located on today's Petersberg. In the 10th century Erfurt came under the secular rule of the archbishops of Mainz, which lasted until the Imperial Deputation in 1803.
In the Middle Ages, Erfurt was a staging post on the once important east-west long-distance trade route, the trade fair route from Leipzig via Cologne to the Duchy of Brabant, which is why it is also called the Brabant Road.
Erfurt has preserved outstanding evidence of Jewish culture from the high and late Middle Ages. These include the OldSynagogue, whose construction began in 1094, making it the oldest surviving synagogue in Europe. The adjacent mikveh, dating from the 13th century, is also one of the oldest in Europe. In 1998, a Jewish treasure was found during excavations in Michaelisstraße, the contents of which are among the most important testimonies to Jewish medieval culture in Europe. The first Jewish community came to an abrupt end with a plague pogrom in 1349. From 1354 a second Jewish community arose until the Erfurt council withdrew the protection of the Jews in 1453/54 and forced them to emigrate. It was not until the 19th century that Jews again settled in the city.
With a population of around 18,000 to 20,000, the city developed into a major medieval city in the 14th and 15th centuries, surpassed in size only by Cologne, Nuremberg and Magdeburg. Erfurt thus reached the peak of its economic, political and intellectual-cultural development in the Middle Ages and became the centre of trade in the central Holy Roman Empire. This included Erfurt's development into one of the largest woad markets in the empire, which began as early as the 13th century. In 1331 Erfurt received the trade fair privilege from Emperor Ludwig IV.
Already in the 13th century, the city had grown into an educational centre of far-reaching importance. No other city in Germany had more students in the second half of the 13th century. In the first half of the 14th century, the Erfurt Studium generale developed into the most important educational institution in the Roman-German Empire. In 1392 the city - and not the archbishop - opened the third university on German soil, which with its founding privilege of 1379 can also be considered the oldest.
early modern period
One of the most famous graduates of the University of Erfurt was Martin Luther, who studied here from 1501 to 1505 and received his master's degree from the Faculty of Philosophy. During the Reformation, the majority of the city turned to the Lutheran confession. In 1521, the first Lutheran pastor, Georg Petz, was appointed. The Erfurt council signed the Lutheran Formula of Concord of 1577.
On April 21, 1618, a treaty was signed between the Archbishop of Mainz, Johann Schweikhard von Cronberg, and the city of Erfurt, which confirmed the religious freedom already granted earlier and expressly extended it to the Erfurt countryside. As for the legal status of the city, it was stipulated that it was the property of the Archbishopric of Mainz and renounced any imperial status. The Thirty Years' War severely damaged the city. Erfurt was occupied by the Swedes from 1632 to 1635 and from 1637 to 1650. The Peace of Westphalia did not bring the city the hoped-for imperial freedom. This again triggered years of conflict.
In 1664, French and imperial troops of the Elector of Mainz and Archbishop Johann Philipp von Schönborn conquered the city. This restored Electoral-Mainzian rule. Erfurt was now ruled as the capital of the Erfurt State together with the Eichsfeld by a Mainz governor, who had his seat in the Elector Mainz Governor's Office (today's State Chancellery). In order to prevent further uprisings and as protection against the Protestant powers, the Elector Palatine and Archbishop, Johann Philipp von Schönborn, had a citadel built on the site of the Petersberg.
In 1682 and 1683 Erfurt experienced the worst plague years in its history; in 1683 alone more than half the population succumbed to the deadly disease.
In Erfurt, witch hunts are known from 1526 to 1705. Trial records are only incompletely available. Twenty people were put on witch trials, at least eight people were killed. In 1705, the 42-year-old goose herder Anna Martha Hausburg from Mittelhausen was tortured, beheaded and then burned. Her 7-year-old daughter Katharina Christina had to watch her mother's execution.
19th century
In 1802, in accordance with the Reichsdeputationshauptschluss, the city and countryside of Erfurt came to Prussia as compensation for lost territories on the left bank of the Rhine. After Napoleon's victory over Prussia at the Battle of Jena and Auerstedt, French troops occupied the fortress without a fight on 16 October 1806 after its surrender. In 1807 Napoleon declared Erfurt together with Blankenhain as the Principality of Erfurt an imperial domain, which was not part of the Confederation of the Rhine but directly subordinate to it.
In 1814, after a successful siege of Erfurt by Prussian, Austrian and Russian troops, the French occupation ended, and in 1815, as a result of the Congress of Vienna, Erfurt was once again awarded to Prussia, which ceded most of its territory and the Blankenhain area to Saxony-Weimar-Eisenach. The hardship prevailing at the time was alleviated by British aid money, which also benefited war orphans in particular and was part of the first ever major humanitarian aid campaign. With the establishment of important engineering companies, Erfurt became an important industrial location at the end of the 19th century. Horticulture and seed breeding are still of particular importance today. Native Erfurt residents owe the nickname "Puffbohne" (broad bean) to this. The company "N.L. Chrestensen" has played an important role here since 1867. Around 1900 the commercial horticulture of the "flower city" Erfurt had a leading position worldwide.
20th century
In 1906, Erfurt became a major city with 100,000 inhabitants. The First World War cost the lives of 3579 citizens. When the state of Thuringia with the state capital Weimar was formed in 1920, the Prussian areas of Thuringia including Erfurt were not included due to the resistance of the Prussian government. These, like Erfurt, belonged in part to the province of Saxony. On 26 June 1921, the Thuringian Traditional Costume and Heritage Festival was held in Erfurt.
After positive development from 1923 to 1928, the city was massively affected by the world economic crisis from 1929.
In 1933, the NSDAP took control of the city. In 1938 Erfurt was one of the largest garrisons in the German Reich.
On Reichspogromnacht, the Great Synagogue was burned down and the deportation of the approximately 800 Jewish residents began. The Memorial Book of the Federal Archives for the Victims of the National Socialist Persecution of Jews in Germany (1933-1945) lists by name 447 Jewish residents of Erfurt who were deported and mostly murdered.
Between 1939 and 1945, between 10,000 and 15,000 prisoners of war as well as men and women from numerous countries occupied by Germany were forced to perform forced labor, primarily in armaments factories in the city.
→ Main article: Air raids on Erfurt
During the Second World War, Erfurt experienced 27 British and American air raids, not counting the numerous attacks by fighter-bombers in April 1945. 1100 tons of bombs were dropped. About 1600 civilians lost their lives. 530 buildings were totally destroyed, 2550 severely or moderately damaged. 17% of the dwellings were completely destroyed, many more severely damaged. The historic old town of Erfurt was particularly affected. 23,000 people lost their homes. 100 industrial buildings were destroyed or severely damaged. Valuable secular and sacred buildings were lost, such as the Collegium Maius of the old university and the library of the Augustinian monastery. All the churches in the city centre were hit more or less severely by bombs and artillery fire. The ruins of the Barfüßerkirche, destroyed by an aerial mine on 26 November 1944, still stand today as a memorial. On 3 and 4 April 1945, the Royal Air Force had planned an area bombing raid on Erfurt using 2740 tons of bombs. The attack was cancelled due to the rapid advance of US ground troops.
On 12 April 1945, units of the 3rd US Army under the command of General George S. Patton occupied Erfurt, after fighting in the city and its surroundings. On 1 July, the Prussian district government ceased its activities. The city was assigned to the state of Thuringia along with the administrative district of Erfurt. On 3 July, due to the 1st London Zone Protocol of 1944 and the decisions of the Yalta Conference, units of the Red Army took over the city, Erfurt became part of the Soviet occupation zone.
Erfurt began to slowly recover from the effects of the war. 30,000 cubic metres of rubble were cleared from the streets, the tramway and gas supply were put back into operation and the schools reopened. After the dissolution of the state of Prussia on 25 February 1947, which was also legally executed by the Allied Control Council Act No. 46, the Thuringian state parliament declared Erfurt the state capital of Thuringia on 7 July 1948, before the state of Thuringia was dissolved in 1952 and divided into three districts, with Erfurt becoming the seat of the Erfurt district.
During the GDR era, large-scale demolition of the Krämpferviertel on the eastern edge of the old town began in the late 1960s. The new construction of 11- to 16-storey and up to 120-metre-long prefabricated slab buildings permanently impaired the cityscape, which had been relatively intact and characterised by church towers until then - despite the destruction caused by the war. In addition, by the end of the 1970s, new residential areas with a total of over 17,000 apartments had been built on the outskirts of the city. The demolition of the Andreasviertel was prevented by citizen protests and the fall of the Berlin Wall in 1989.
In March 1970, Erfurt was the scene of the Erfurt summit meeting between Federal Chancellor Willy Brandt and the Chairman of the Council of Ministers of the GDR, Willi Stoph. Brandt showed up at the window of the Hotel Erfurter Hof, located across from the main train station, among other places. The crowd greeted him enthusiastically with shouts of "Willy, Willy" and "Willy Brandt to the window!".
In 1975, riots in Erfurt resulted in the first pogrom-like incidents in Germany since 1945. The events of 10 to 13 August were directed against Algerian contract workers who had been employed in various Erfurt factories since June 1975. During this period, Algerians were chased through Erfurt city centre by Germans on several occasions and attacked with iron bars and wooden slats, among other things.
In the autumn of 1989, ever larger demonstrations in Erfurt also heralded the turnaround and peaceful revolution in the GDR. In 1991, 49 of 88 members of the state parliament voted for Erfurt as the capital of Thuringia. In 1994, Erfurt University was reestablished; also in that year, the Episcopal Office of Erfurt-Meiningen, which had existed since 1973, was elevated to the status of the Diocese of Erfurt.
21st century
The image of the city has changed significantly in the years since reunification. Many buildings in the historic old town have been renovated, and new buildings have been constructed in some places. The redesign of the Fischmarkt was awarded the special prize of the German Urban Development Prize 2014.
On 26 April 2002, Erfurt became the subject of worldwide media attention as a result of the so-called Erfurt killing spree. The rampage at Gutenberg-Gymnasium was the first rampage perpetrated by a student at a school in Germany. Eleven teachers, a trainee teacher, a secretary, two pupils and a policeman were killed. Afterwards, the 19-year-old rampage killer killed himself.
Since the 1990s, organised crime has been able to gain a foothold in Erfurt with several mafia groups, such as the Italian 'Ndrangheta, but also the Armenian Mafia (thieves under the law). Among other things, there was a robbery and an arson attack in the catering industry, as well as a shooting on the open street in 2014. The Hells Angels rocker group was also active in the city.
In 2016, Erfurt was awarded the honorary title of "Reformation City of Europe" by the Community of Protestant Churches in Europe.

Population development
→ Main article: Population development of Erfurt
In 1880 Erfurt had more than 50,000 inhabitants. In 1906, the city's population exceeded 100,000, making it a major city. Shortly after the end of World War II on 1 December 1945, the city had 164,998 inhabitants, and in 1973 it exceeded 200,000. In 1989, the population reached its historic high of just over 220,000. After the fall of communism in the GDR, the city lost a total of around 20,000 people by 2002 due to emigration, suburbanisation and a decline in the birth rate, despite numerous incorporations in 1994. Since 2003, the number of inhabitants has been rising again, so that so far about a quarter of the post-reunification decline has been compensated for. This means that Erfurt has had the most stable demographic development since 1990 among the comparably sized eastern German cities (Magdeburg, Halle (Saale), Chemnitz and Rostock).
On 31 December 2019, a total of 214,417 people with their main residence could be counted in the population register of the state capital Erfurt. These are divided into 104,630 males and 109,787 females. The number of foreign residents living in Erfurt is currently 18,811. This means that the proportion of foreigners is 8.8 percent. The average age of the population living in Erfurt on this date is 44.3 years.
