→ Main article: History of Mannheim
The beginnings
A brick kiln excavated in 1929 in the Seckenheim district, which operated from 74 AD to the early second century, attests to settlement in Roman times.
The village of Mannenheim (= home of Manno) was first mentioned in the Lorsch Codex in 766.
Through numerous donations within a short period of time, Lorsch Monastery received 160½ days of arable land, which corresponds to the hay yield of a medium-sized royal farm.
In 1284 Mannheim fell to the Count Palatine of the Rhine from the House of Wittelsbach. The customs castle of Eichelsheim, which was built in 1349 on the site of today's Lindenhof, gained regional importance as it demanded a toll from the Rhine boatmen. In 1415, the deposed antipope John XXIII was imprisoned there on behalf of Emperor Sigismund. By defeating the army of his allied opponents, the Count of Württemberg, the Margrave of Baden and the Bishop of Metz, at the Battle of Seckenheim in 1462, Elector Frederick of the Palatinate "the Victorious" established the Palatine supremacy in the middle Upper Rhine. In 1566, Mannheim was one of the largest villages of the Oberamts Heidelberg with about 700 inhabitants.
Emergence of the city
Mannheim was granted city privileges on January 24, 1607, after Elector Friedrich IV of the Palatinate laid the foundation stone for the construction of the Friedrichsburg fortress on March 17, 1606. The planning at that time of a grid-like street network for the burgher city of Mannheim, which was connected to the fortress, has been preserved. During the Thirty Years' War (1618-1648), in which Mannheim fought on the side of the Protestant Union, it was first destroyed by troops in 1622. War and epidemics caused serious population losses in Mannheim, which had about 1200 inhabitants in 1618. On his return to the Electoral Palatinate in 1649, Elector Karl Ludwig von der Pfalz found a country largely depopulated and economically ruined by the destruction of war. The new regent was resolutely committed to the reconstruction of Mannheim, which was destined to become the center of industrial activity and trade in the Electoral Palatinate because of its favorable location at the mouth of the Neckar River on the Rhine. During the War of the Palatinate Succession, Mannheim was conquered by French troops in 1688 and completely destroyed in March 1689, and the population was expelled. After this destruction, Elector Johann Wilhelm was largely responsible for the renewed reconstruction. Even before the peace treaty was signed, the Elector issued a proclamation in 1697 ordering the reconstruction of the city and calling on the refugees to return. After the reconstruction work began, the population increased again quite quickly.
Residence city of the Electoral Palatinate
In 1720, Elector Carl Philipp moved his court from Heidelberg to Mannheim and began building Mannheim Castle (completed together with the Jesuit Church in 1760). Mannheim became the royal seat of the Electoral Palatinate, and a glorious period of splendor began for the city, which now had a population of 25,000 and lasted only 58 years.
The Electoral Palatinate court promoted art and music, science and trade. Goethe, Schiller and Lessing stayed in Mannheim, as did Mozart.
In 1778, Elector Carl Theodor moved his residence to Munich to take up his Bavarian inheritance. This marked the beginning of an economic and cultural bloodletting in Mannheim.
Baden industrial city
In 1795, the city was occupied by the French and subsequently recaptured by Austrian troops. In 1803 Mannheim finally lost its political position: In the course of the Reichsdeputationshauptschluss, the city fell to Baden, in which it - geographically pushed to the northwestern edge - had only the status of a border town.
In the climatic catastrophe of the "year without a summer" in 1816, which was caused by the eruption of the Tambora volcano and resulted in famine and the death of horses, Karl Drais invented the two-wheeler and thus mechanized individual transport. In 1828 the Rhine harbor was opened, and in 1840 the first Baden railroad line from Mannheim to Heidelberg. Characterized by the economic rise of the bourgeoisie, Mannheim gradually began to flourish again. In the March Revolution of 1848, the city was a center of the political and revolutionary movement. In 1865, Friedrich Engelhorn founded the Badische Anilin- und Soda-Fabrik (BASF), although it was later moved to Ludwigshafen. The dye factory became the largest chemical company in the world. In 1880, Werner von Siemens presented the world's first electric elevator in Mannheim. In 1886, Carl Benz patented his velocipede with gas engine operation. In 1909, Karl Lanz and Johann Schütte founded the Schütte-Lanz company, which built a total of 22 airships. The company was the main competitor of Zeppelin-Werke. After World War I, Heinrich Lanz AG introduced the Bulldog, the most successful heavy oil tractor. The pre-chamber diesel engine invented by Prosper L'Orange at Motorenwerke Mannheim was further developed at Benz & Cie into the world's first compact vehicle diesel engine in 1923. In 1922, the large power plant in Mannheim went into operation. Around 1930, the city had a population of 385,000, together with its sister city Ludwigshafen, which developed from Mannheim's old Rhine redoubt.
From the Third Reich until today
During the Third Reich, almost 2,000 Mannheim residents with a Jewish background were deported. There were around 140 places in the city where forced laborers were housed, many also near the large companies that employed forced laborers and prisoners of war during the Nazi era. In the Sandhofen district, there was one subcamp each of the Natzweiler-Struthof concentration camp and the Hinzert concentration camp.
Mannheim was almost completely destroyed by air raids on Mannheim during World War II. The city was finally occupied by US troops at the end of March 1945. The war, which was still continuing elsewhere in Germany, ultimately ended only on May 8 with the unconditional surrender of the Wehrmacht.
The reconstruction of the city began only with difficulty. The castle and water tower were rebuilt, and the National Theater was erected on a new site. A Schiller monument and the pub Zum Zwischen-Akt stand on the old site. The housing shortage led to the development of numerous new residential areas.
In 1964, the Municipal Hospital on the Neckar became the Faculty of Clinical Medicine Mannheim at the University of Heidelberg. In 1967, Mannheim became a university city.
In 1975, the Federal Garden Show was a highlight in Luisenpark and Herzogenriedpark. A number of structural measures were implemented: the telecommunications tower and a second Rhine bridge were built, the Planken became a pedestrian zone, the new Rose Garden was inaugurated, and the Aerobus floated through Mannheim. A number of major projects were also realized in the 1980s and 1990s: the planetarium, the Kunsthalle extension, the new Reiß Museum, the Stadthaus, the new Maimarkt site, the synagogue, the mosque, the State Museum of Technology and Labor (Technoseum), the Carl Benz Stadium and the Fahrlachtunnel were opened.
In May/June 1992, there were days of riots on the occasion of the accommodation of refugees in the (now demolished) Gendarmerie barracks in the Schönau district (see List of anti-refugee attacks in Germany 1990 to 2013#1992).
Economically, Mannheim has been characterized in the recent past by a decline in industrial jobs. The city tried to shape this structural change by designating industrial estates and attracting service companies. A prime example is the construction of the Victoria high-rise in 2001, one of the tallest buildings in the city, on the railroad site.
In view of the 400th city anniversary in 2007, a number of urban development activities were implemented from 2000 onward: SAP Arena with connection to the new eastern light rail ring, redevelopment of the Breite Strasse pedestrian zone, the Zeughaus and the castle, complete redesign of the Alter Meßplatz and the new Schafweide light rail line. The concept of the city anniversary aimed at a diverse spectrum of events without a dominating central event.
During the 2015 refugee crisis in Europe, Mannheim took in 12,000 refugees, mostly in former U.S. Army barracks.

Incorporations
Between 1895 and 1944, several surrounding villages were incorporated into Mannheim, including Neckarau, which was the largest village in Baden at the time. During the major municipal reform in the 1970s, there were plans to incorporate Brühl, Ilvesheim, Edingen-Neckarhausen and Ladenburg. However, due to large protests, they refrained from doing so, and Mannheim was one of the few cities in Baden-Württemberg that did not receive an increase in area. Before the first incorporation, the city area covered 2384 hectares:
| Year | Places | Increase in hectares |
| 1895 | Friesenheim Island | 717 |
| 1897 | Käfertal | 1777 |
| 1899 | Neckarau | 1575 |

| 1913 | Sandhofen | 2437 |
| 1913 | Rheinau | 959 |
| 1929 | Wallstadt | 674 |
| 1930 | Seckenheim | 1687 |
| 1930 | Friedrichsfeld | 225 |

Population development
→ Main article: Population development of Mannheim
The population of the city of Mannheim exceeded 100,000 in 1896, making it a major city. In 1905, the city had over 160,000 inhabitants, and by 1961 this number had doubled. In 1970, the population reached its historic high of around 333,000. Due to migration losses to the surrounding areas and a negative birth and death rate, the number of inhabitants dropped to around 295,000 by 1986. Currently, the increased influx into metropolitan areas also applies to Mannheim.
For December 31, 2015, the Municipal Statistics Office of the City of Mannheim lists 337,919 residents, of which 317,744 are primary residents.
The proportion of foreigners is 25.2% (79,963 persons) in relation to their main place of residence. Taking into account naturalized persons and ethnic German immigrants, 138,428 residents (43.6%) have a migration background. The largest immigrant groups come from:
In the individual city districts, the proportion of residents with a migration background is:
- City center/Jungbusch 61.9
- Neckarstadt-West 69.1 %
- Neckarstadt East 50.2
- Schwetzingerstadt/East City 38.2 %

Religions and worldviews
Denomination statistics
According to the 2011 census, at that time 29.8% of the city's population was Catholic, 26.5% Protestant, and 43.7% belonged to another religious community or to no religious community under public law (adjusted register population). The number of Protestants and Catholics has decreased since then and the persons who do not belong to any religious community under public law are an absolute majority of the population. The current distribution of the city's population by religious affiliation (as of December 31, 2020) is Roman Catholic 25.4%, Protestant 20.0%, and other/none 54.6%.(53.5% in 2019)
Precise figures on other religious communities (in addition to the two official churches) were last collected in the 2011 census: At that time, 0.7% of the population were Evangelical Free Churches, 2.6% Orthodox. According to a calculation based on the census figures for persons with a migration background, Muslims accounted for 10.8% of the population in 2011.
Protestants
Elector Ottheinrich introduced the Reformation of the Lutheran confession in the Electoral Palatinate by mandate of April 4, 1556, after his predecessor Frederick II had already made serious efforts in this direction ten years earlier (first Lutheran communion in the Heiliggeistkirche in Heidelberg on April 18, 1546). Under Ottheinrich's successor Friedrich III, the Electoral Palatinate switched to the Reformed confession of Calvinist character from 1561 (Heidelberg Catechism 1563). The time of the founding of the city of Mannheim thus fell into the phase of Electoral Palatine Reformedism, which gave the city a Reformed-Protestant character for a long time.
In 1821, the union between Lutheran and Reformed congregations was carried out in the Grand Duchy of Baden. In 2005, the first youth church of the Protestant regional church of Baden was opened in the Waldhof district. With the incorporation of the previously independent Evangelische Kirchengemeinde Friedrichsfeld in 2008, all Protestant congregations, unless they belong to a free church, are part of the Mannheim church district within the Nordbaden church district of the Evangelische Landeskirche in Baden. The church district of North Baden has its seat in Schwetzingen.
Catholics
The first churches can be traced back to the 8th century in the suburbs of Scharhof, Wallstadt and Feudenheim. A parish in Mannheim itself was first mentioned in the 14th century. It belonged to the diocese of Worms and was dedicated to St. Sebastian. The oldest Catholic church is the parish church of St. Sebastian on the market square, which was completed in 1723. In 1729, Elector Karl Philipp donated 100,000 florins for the construction of the Jesuit Church, which was to serve as the court church. Together with the Liebfrauenkirche, it has belonged to a joint parish of St. Sebastian since 2005. The other 28 Roman Catholic parishes are grouped into ten pastoral units and belong to the Mannheim City Deanery of the Archdiocese of Freiburg.
Other churches
There are also several Orthodox parishes, including the Russian Orthodox Church of St. Alexander Nevsky and the Greek Orthodox Church of the Exaltation of the Holy Cross.
Protestant free churches are also numerous. These include, for example, the Free Evangelical Church (FEG), the congregation Haus des Herrn (HdH-Mannheim) in Mannheim-Rheinau, the Free Church of the Seventh-day Adventists (STA) and the Evangelical Free Church (Baptist). Their Hope Church has been located in the Neckarstadt district since 1961.
The congregation of the Old Catholic Church has been at home since 1873 in the Schlosskirche and in Mannheim's only blue church, the Erlöserkirche Gartenstadt.
In addition, there are other Christian denominations in Mannheim today, including the New Apostolic Church, Jehovah's Witnesses, and a Free Religious congregation that was founded during the Baden Revolution in the mid-19th century.
Jews
→ Main article: Jewish community Mannheim
The first synagogue was built in Mannheim in 1660. Especially after the destruction of the city in the 17th century, the electors specifically promoted the settlement of Jews with tax concessions and the privilege of freedom of trade to help trade and crafts flourish. In 1719, 10.6% of the population were Jewish. By 1895, the Jewish community had grown to 4768 members. However, the rest of the population grew even more rapidly, so that after 1900 the Jewish proportion was only around three percent. In 1933, 6402 Jews lived in Mannheim, forming the largest community in Baden.
Due to the repressive measures after the National Socialists seized power, many Jews found themselves in need at an early stage. As early as 1933, the mayor at the time, Carl Renninger (NSDAP), forbade the awarding of contracts to Jewish companies. Jewish lecturers at the local commercial college were suspended, the Mannheim National Theater dismissed Jewish actors, and Jewish doctors had their health insurance licenses revoked. Many families emigrated abroad, especially to the United States. After the devastation of the three Mannheim synagogues in 1939, about 2000 and thus almost all remaining Jews were deported to Gurs in 1940. Most were deported from there to the German concentration camps in occupied Poland and murdered.
After the Second World War, only a few emigrants returned to Mannheim. The re-establishment of the Jewish community after the Nazi persecution took place with only 120 members. The new synagogue of the Jewish community was opened in 1987. In 2012, the community had about 500 members.
Muslims
With the second wave of guest workers in the mid-1960s, many immigrants from Turkey came to Mannheim, and with them a significant number of Muslims for the first time. Their number rose to 20,827 by 2004, seven percent of Mannheim's population, the majority of them being immigrants from Muslim countries and their descendants. In 1995, therefore, the Yavuz Sultan Selim Mosque, by then the largest mosque in Germany, was built, offering 2,500 places for prayer. In 2005, the minaret, which had already fallen into disrepair, was rebuilt slimmer and taller. In 2010, the Ehsan Mosque of the Ahmadiyya Muslim Jamaat was built in Mannheim-Casterfeld. There are also other mosques in the districts of Innenstadt/Jungbusch (three), Neckarstadt-West (two) and Neckarstadt-Ost, Waldhof, Neckarau, Rheinau and Hochstätt (one each).
Evolutionary Humanism
The Giordano Bruno Foundation, which represents Evolutionary Humanism, is represented by the Secular Humanists - gbs Rhein-Neckar e. V., founded in Mannheim in 2010.
