Chancellor of Germany in the context of "Friedrich Merz"

The social market economy (SOME; German: soziale Marktwirtschaft, German pronunciation: [zoˌt͡si̯aːlə ˈmaʁktˌvɪʁtʃaft] ), also called Rhine capitalism, Rhine-Alpine capitalism, the Rhenish model, and social capitalism, is a socioeconomic model and ideology combining a free-market capitalist economic system with social policies and enough regulation to establish both fair competition within the market and generally a welfare state. It is sometimes classified as a regulated market economy. The social market economy was originally promoted and implemented in West Germany by the Christian Democratic Union under Chancellor Konrad Adenauer in 1949 and today it is used by ordoliberals, social liberals and social democrats alike. Its origins can be traced to the interwar Freiburg school of economic thought.

The social market economy was designed to be a middle way between laissez-faire forms of capitalism and socialist economics. It was strongly inspired by ordoliberalism, which was influenced by the political ideology of Christian democracy. Social market refrains from attempts to plan and guide production, the workforce, or sales but support planned efforts to influence the economy through the organic means of a comprehensive economic policy coupled with flexible adaptation to market studies. Combining monetary, credit, trade, tax, customs, investment, and social policies, as well as other measures, this type of economic policy aims to create an economy that serves the welfare and needs of the entire population, thereby fulfilling its ultimate goal.

Nazi Germany, officially the German Reich and later the Greater German Reich, was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a totalitarian dictatorship. The Third Reich, meaning "Third Realm" or "Third Empire", referred to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which the Nazis referred to as the Thousand-Year Reich, ended in May 1945, after 12 years, when the Allies defeated Germany and entered the capital, Berlin, ending World War II in Europe.

After Hitler was appointed Chancellor of Germany in 1933, the Nazi Party began to eliminate political opposition and consolidate power. A 1934 German referendum confirmed Hitler as sole Führer (leader). Power was centralised in Hitler's person, and his word became the highest law. The government was not a co-ordinated, cooperating body, but rather a collection of factions struggling to amass power. To address the Great Depression, the Nazis used heavy military spending, extensive public works projects, including the Autobahnen (motorways) and a massive secret rearmament program, forming the Wehrmacht (armed forces), all financed by deficit spending. The return to economic stability and end of mass unemployment boosted the regime's popularity. Hitler made increasingly aggressive territorial demands, seizing Austria in the Anschluss of 1938, and the Sudetenland region of Czechoslovakia. Germany signed a non-aggression pact with the Soviet Union and invaded Poland in 1939, launching World War II in Europe. In alliance with Fascist Italy and other Axis powers, Germany conquered most of Europe by 1940 and threatened Britain.

Adolf Hitler (20 April 1889 – 30 April 1945) was an Austrian-born German politician who was the dictator of Germany during the Nazi era, which lasted from 1933 until his suicide in 1945. He rose to power as the leader of the Nazi Party, becoming the chancellor of Germany in 1933 and then taking the title of Führer und Reichskanzler in 1934. Germany's invasion of Poland on 1 September 1939 under his leadership marked the outbreak of the Second World War. Throughout the ensuing conflict, Hitler was closely involved in the direction of German military operations as well as the perpetration of the Holocaust, the genocide of about six million Jews and millions of other victims.

Hitler was born in Braunau am Inn in Austria-Hungary and moved to Germany in 1913. He was decorated during his service in the German Army in the First World War, receiving the Iron Cross. In 1919, he joined the German Workers' Party (DAP), the precursor of the Nazi Party, and in 1921, was appointed the leader of the Nazi Party. In 1923, he attempted to seize governmental power in a failed coup in Munich and was sentenced to five years in prison, serving just over a year. While there, he dictated the first volume of his autobiography and political manifesto Mein Kampf (lit. 'My Struggle'). After his early release in 1924, he gained popular support by attacking the Treaty of Versailles as well as promoting pan-Germanism, antisemitism, and anti-communism with charismatic oratory and Nazi propaganda. He frequently denounced communism as being part of an international Jewish conspiracy. By November 1932, the Nazi Party held the most seats in the Reichstag, but not a majority. Former chancellor Franz von Papen and other conservative politicians convinced President Paul von Hindenburg to appoint Hitler as chancellor on 30 January 1933. Shortly thereafter on 23 March, the Reichstag passed the Enabling Act of 1933, which ultimately began the Weimar Republic's transformation into Nazi Germany.

At the Congress of Berlin (13 June – 13 July 1878), the major European powers revised the territorial and political terms imposed by the Russian Empire on the Ottoman Empire by the Treaty of San Stefano (March 1878), which had ended the Russo-Turkish War of 1877–1878. The Congress was the result of escalating tensions; particularly British opposition to Russian hegemony over the Ottoman Empire in the Balkans, through the creation of a Russian-aligned 'Greater Bulgaria'. To secure the European balance of power in favour of its splendid isolation achieved after the Crimean War, Britain stationed the Mediterranean Fleet near Constantinople to enforce British demands. To avoid war, Otto von Bismarck, Chancellor of the newly formed German Empire, was asked to mediate a solution that would restore the Ottoman Empire's position as a counterbalance to Russian influence in the Mediterranean and the Balkans, in line with the principles of the 1856 Treaty of Paris.

Attended by delegates from Europe's then six great powers: Russia, Great Britain, France, Austria-Hungary, Italy, and Germany; the Ottomans as well as representatives of four Balkan states (Greece, Serbia, Romania and Montenegro), the Congress culminated in the Treaty of Berlin (13 July 1878). This agreement essentially dismantled the autonomous Greater Bulgarian State envisaged at San Stefano, and reorganised the borders of south-eastern Europe. The main results were the Austro-Hungarian forcible occupation of Bosnia and Herzegovina, the British de facto annexation of Cyprus under false pretenses, and the formal recognition of the self-declared independence of Romania, Serbia and Montenegro; allies of Russia in the previous war. While the settlement averted war, it exacerbated nationalist grievances in the Balkans and deepened the rivalry between Britain and Russia (The Great Game), contributing to long-term regional instability that foreshadowed the Balkan Wars and World War I.

The German Empire (German: Deutsches Reich), also referred to as Imperial Germany, the Second Reich, or simply Germany, was the period of the German Reich from the unification of Germany in 1871 until the November Revolution in 1918, when Germany changed its form of government to a republic. The German Empire consisted of 25 states, each with its own nobility: four constituent kingdoms, six grand duchies, five duchies (six before 1876), seven principalities, three free Hanseatic cities, and one imperial territory. While Prussia was only one of the four kingdoms in the realm, it contained about two-thirds of the Empire's population and territory, and Prussian dominance was also constitutionally established, since the King of Prussia was also the German Emperor (Deutscher Kaiser).

The empire was founded on 18 January 1871, when the south German states, except for Austria, Switzerland and Liechtenstein, joined the North German Confederation. The new constitution came into force on 16 April, changing the name of the federal state to the German Empire and introducing the title of German Emperor for Wilhelm I, King of Prussia from the House of Hohenzollern. Berlin remained its capital, and Otto von Bismarck, Minister President of Prussia, became chancellor, the head of government. After 1850, the states of Germany had rapidly become industrialized. In 1871, Germany had a population of 41 million people; by 1913, this had increased to 68 million. A heavily rural collection of states in 1815, the now united Germany became predominantly urban. German factories were often larger and more modern than many of their British and French counterparts, but the preindustrial sector was more backward. The success of the German Empire in the natural sciences was such that one-third of all Nobel Prizes went to German inventors and researchers. During its 47 years of existence, the German Empire became an industrial, technological, and scientific power in Europe, and by 1913, Germany was the largest economy in continental Europe and the third largest in the world. Germany also became a great power, building the longest railway network of Europe, the world's strongest army, and a fast-growing industrial base. Starting very small in 1871, in a decade, the navy became second only to Britain's Royal Navy.

The Schuman Declaration, or Schuman Plan, was a proposal to place French and West German production of coal and steel under a single authority that later became the European Coal and Steel Community, made by the French foreign minister, Robert Schuman, on 9 May 1950 (now celebrated in the EU as Europe Day), the day after the fifth anniversary of the end of World War II in Europe. The alliance would later be opened to other European countries. The ultimate goal was to pacify relations, especially between France and West Germany, through gradual political integration to be achieved by creating common interests. Schuman said that "[t]he coming together of the countries of Europe requires the elimination of the age-old opposition of France and Germany ... the solidarity in production thus established will make it plain that any war between France and Germany becomes not merely unthinkable, but materially impossible."

Konrad Adenauer, the first Chancellor of the Federal Republic of Germany, responded positively to the Declaration, as did the governments of the Netherlands, Belgium, Italy, and Luxembourg. On 18 April 1951, the six founding members signed the Treaty of Paris. It created the European Coal and Steel Community – Europe's first supranational community, which paved the way for the European Economic Community and subsequently the European Union.

The Christian Democratic Union of Germany (German: Christlich Demokratische Union Deutschlands [ˈkʁɪstlɪç demoˈkʁaːtɪʃə ʔuˈni̯oːn ˈdɔʏtʃlants], CDU [ˌtseːdeːˈʔuː] ) is a Christian democratic and conservative political party in Germany. It is the major party of the centre-right in German politics. Friedrich Merz has been federal chairman of the CDU since 31 January 2022, and has served as the Chancellor of Germany since 6 May 2025.

The CDU is the largest party in the Bundestag, the German federal legislature, with 208 out of 630 seats, having won 28.5% of votes in the 2025 federal election. It forms the CDU/CSU Bundestag faction, also known as the Union, with its Bavarian counterpart, the Christian Social Union in Bavaria (CSU). The group's parliamentary leader has been Jens Spahn since 5 May 2025.

Konrad Hermann Joseph Adenauer (5 January 1876 – 19 April 1967) was a German statesman and politician who served as the first chancellor of West Germany from 1949 to 1963. From 1946 to 1966, he was the first leader of the Christian Democratic Union (CDU), a newly founded Christian democratic party, which became the dominant force in the country under his leadership.

As a devout Catholic, Adenauer was a leading politician of the Catholic Centre Party in the Weimar Republic, serving as Mayor of Cologne (1917–1933) and as president of the Prussian State Council. In the early years of the Federal Republic, he switched focus from denazification to recovery, and led his country to close relations with France, the United Kingdom, and the United States. During his years in power, he worked to restore the West German economy from the destruction of World War II to a central position in Europe with a market-based liberal democracy, stability, international respect and economic prosperity.
