Pan-Germanism (German: Pangermanismus or Alldeutsche Bewegung) is a pan-nationalist political idea. Pan-Germanists originally sought to unify all the German-speaking populations of Europe in a single nation-state known as Großdeutschland (Greater Germany), where "German-speaking" was taken to include the Low German, Frisian and Dutch-speaking populations of the Low Countries, and sometimes also as synonymous with Germanic-speaking, to the inclusion of Scandinavia.
Pan-Germanism was highly influential in German politics in the 19th century during the unification of Germany when the German Empire was proclaimed in as a nation-state in 1871 without Austria (Kleindeutsche Lösung/Lesser Germany), and the first half of the 20th century in the Austro-Hungarian Empire and the German Empire. From the late 19th century, many Pan-Germanist thinkers, since 1891 organized in the Pan-German League, had adopted openly ethnocentric and racist ideologies, and ultimately gave rise to the foreign policy Heim ins Reich pursued by Nazi Germany under Adolf Hitler from 1938, one of the primary factors leading to the outbreak of World War II. As a result of the disaster of World War II, Pan-Germanism was mostly seen as a taboo ideology in the postwar period in both the Federal Republic of Germany and the German Democratic Republic. Pan-Germanism remains practically extinct as an ideology, at best limited to some fringe groups of Neo-Nazism in Germany and Austria.
Origins (before 1860) 
Pan-Germanism's origins began with the birth of Romantic nationalism during the Napoleonic Wars, with Friedrich Ludwig Jahn and Ernst Moritz Arndt being early proponents. Germans, for the most part, had been a loose and disunited people since the Reformation, when the Holy Roman Empire was shattered into a patchwork of states following the end of the Thirty Year's War with the Peace of Westphalia.
Advocates of the Großdeutschland (Greater Germany) solution sought to unite all the German-speaking people in Europe, under leadership of the Austrians Germans from the Austrian Empire. Pan-Germanism was widespread among the revolutionaries of 1848, notably among Richard Wagner and the Brothers Grimm. Writers such as Friedrich List and Paul Anton Lagarde argued for German hegemony in Central and Eastern Europe, where German domination in some areas had begun as early as the 9th century AD with the Ostsiedlung, Germanic expansion into Slavic and Baltic lands. For the Pan-Germanists this movement was seen as a Drang Nach Osten, in which Germans would be naturally inclined to seek Lebensraum by moving eastwards to reunite with the German minorities there.
The Deutschlandlied ("Song of Germany"), written in 1841 by Hoffmann von Fallersleben, in its first stanza defines Deutschland as reaching " From the Meuse to the Memel / From the Adige to the Belt", i.e. as including East Prussia and South Tyrol.
The German question 
By the 1860s the Kingdom of Prussia and the Austrian Empire were the two most powerful nations dominated by German-speaking elites. Both sought to expand their influence and territory. The Austrian Empire — like the Holy Roman Empire — was a multi-ethnic state, but the German-speaking people there did not have an absolute numerical majority; the creation of the Austro-Hungarian Empire was one result of the growing nationalism of other ethnicities especially the Hungarians. Under Prussian leadership Otto von Bismarck would ride on the coat-tails of nationalism to unite all of modern-day Germany. After Bismarck excluded Austria and the Austrian Germans from Germany in the German war and following a few other events over the next few years, the unification of Germany, created the Prussian-dominated German Empire ("Second Reich") in 1871 following the proclamation of Wilhelm I as head of a union of German-speaking states, while disregarding millions of its non-German subjects who desired self-determination from German rule.
Integrating the Austrian Germans nevertheless remained a strong desire for many people of Germany and Austria, especially among the liberals, the social democrats and also the Catholics who were a minority in Germany.
German nationalism in Austria 
After the Revolutions of 1848/49, in which the liberal nationalistic revolutionaries advocated the Greater German solution, the Austrian defeat in the Austro-Prussian War (1866) with the effect that Austria was now excluded from Germany, and increasing ethnic conflicts in the multinational Habsburg Monarchy, a German national movement evolved in Austria. Led by the radical German nationalist and anti-semite Georg von Schönerer, organisations as the Pan-German Society demanded the link-up of all German-speaking territories of the Danube Monarchy to the German Empire, and decidedly rejected Austrian patriotism. Schönerer's völkisch and racist German nationalism was an inspiration to Hitler's ideology. In 1933, Austrian Nazis and the national-liberal Greater German People's Party formed an action group, fighting together against the Austrofascist regime which imposed a distinct Austrian national identity and in accordance said that Austrians were "better Germans", while Kurt Schuschnigg adopted a policy of appeasement towards Austrian-born Hitler's annexing of Austria to the Third Reich and called Austria the "better German state" he still struggled to keep Austria independent. With "Anschluss" of Austria in 1938, the historic aim of Austria's German nationalists was achieved. After 1945, the German national camp was revived in the Federation of Independents and the Freedom Party of Austria.
Pan-German League 
The Pan-German Movement was officially founded in 1891, when Ernst Hasse, a professor at the University of Leipzig and a member of the Reichstag, who organized the Pan-German League an ultra-nationalist political interest organization which promoted imperialism, anti-semitism, and support for Ethnic German minorites in other countries. The organization achieved great support among the educated middle and upper class, the organization promoted German nationalist consciousness, especially among ethnic Germans outside Germany. In his three-volume work, "Deutsche Politik" (1905–07), Hasse called for German imperialist expansion in Europe. Similar expansionist policies were preached by Munich professor Karl Haushofer, Ewald Banse, and Hans Grimm, author of Volk ohne Raum and his brother Jacob who published a treaty about German "Volksrecht". Georg Schönerer and Karl Hermann Wolf articulated Pan-Germanist sentiments in Austria-Hungary.
The position of the Pan-German League gradually evolved[clarification needed] into biological racism, with the belief that Germans are a "superior race" and that Germans need protection from mixing with other races, particularly Jews. By 1912, in the publication "If I were the Kaiser", the Pan-German League's leading member Heinrich Class called on Germans to conquer Eastern territories inhabited by "inferior" Slavs, depopulate their territories, and settle German colonists there.
Pan-Germanic tendencies were also widespread among the Norwegian independence movement, notably proposed by Peter Andreas Munch, and Bjørnstjerne Bjørnson. Prominent cultural personalities like Knut Hamsun and Henrik Ibsen also expressed sympathy for the Pan-German idea. Bjørnson, who wrote the lyrics for the Norwegian national anthem, proclaimed in 1901:
I'm a Pan-Germanist, I'm a Teuton, and my greatest dream is for the Northern Germans and the Western Germans to unite in a fellow Confederation.—Bjørnson, 
Jacob Grimm adopted Munch's anti-Danish Pan-Germanism and argued that the entire peninsula of Jutland had been populated by Germans before the arrival of the Danes and that there it could justifiably be reclaimed by Germany, whereas the rest of Denmark should be incorporated into Sweden. This line of thinking was countered by Jens Jacob Asmussen Worsaae, an archaeologist who had excavated parts of Danevirke, who argued that there was no way of knowing the language of the earliest inhabitants of Danish territory, that Germans had more solid historical claims to large parts of France and England, and that Slavs by the same reasoning could annex parts of Eastern Germany. Regardless of the strength of Worsaae's arguments, pan-Germanism spurred on the German nationalists of Schleswig and Holstein and lead to the First Schleswig War in 1848. In turn, this likely contributed to the fact that Pan-Germanism never caught on in Denmark as much as it did in Norway.
1918 to 1945 
World war I became the first attempt to carry out the Pan-German ideology in practice, and the Pan-German movement argued forcefully for an expansionist imperialism providing the German people with Lebensraum.
Following the defeat in World War I, influence of German-speaking elites over Central and Eastern Europe was greatly limited. At the Treaty of Versailles, Germany was substantially reduced in size. Austria-Hungary was split up. A Rump-Austria, which to a certain extent corresponded to the German-speaking areas of Austria-Hungary (a complete split into language groups was impossible due to multi-lingual areas and language-exclaves) adopted the name "German Austria" (German: Deutschösterreich) in hope for union with the Germany. Union with Germany and the name "German Austria" was forbidden by the Treaty of St. Germain and had to be changed back to Austria.
It was in the post-WWI period that the Austrian-born Adolf Hitler, under the influence of the stab-in-the-back myth, first took up German nationalist ideas in his Mein Kampf. Hitler met Heinrich Class in 1918, and Class provided Hitler with support for the 1923 Beer Hall Putsch. Hitler and his National Socialist friends shared most of the basic pan-German visions with the Pan-German League, but nonetheless differences in political style lead the two groups to open rivalry. The German Workers Party of Bohemia cut its ties to the pan-German movement, which was seen as being too dominated by the upper classes, and joined forces with the German Workers Party led by Anton Drexler, which later became the National Socialist German Workers Party (Nazi party) that was to be headed by Adolf Hitler from 1921.
Nazi propaganda also used the political slogan Ein Volk, ein Reich, ein Führer ("One people, one Reich, one leader"), in order to enforce pan-German sentiment in Austria for the "Anschluss"
The Heim ins Reich initiative (German: literally Home into the Empire, meaning Back to the Reich, see Reich) was a policy pursued by the Nazis which attempted to convince the ethnic Germans living outside of the Third Reich (such as in Austria and Sudetenland) that they should strive to bring these regions "home" into a Greater Germany. This notion also led the way for an even more expansive state to be envisioned, the Greater Germanic Reich, which Nazi Germany tried to establish. This pan-Germanic empire was expected to assimilate practically all of Germanic Europe into an enormously expanded Greater Germanic Reich. Territorially speaking, this encompassed the already-enlarged German Reich itself (consisting of pre-1938 Germany proper, Austria, Bohemia, Moravia, Alsace-Lorraine, Eupen-Malmedy, Memel, Lower Styria, Upper Carniola, Southern Carinthia, and German-occupied Poland), the Netherlands, the Flemish part of Belgium, Luxembourg, Denmark, Norway, Sweden, Iceland, at least the German-speaking parts of Switzerland, and Liechtenstein. The most notable exception was the predominantly Anglo-Saxon United Kingdom, which was not projected as having to be reduced to a German province but to instead become an allied seafaring partner of the Germans.
History since 1945 
World War II brought about the decline of Pan-Germanism, much as World War I had led to the demise of Pan-Slavism. Parts of Germany itself were devastated, and the country was divided, firstly into Soviet, French, American, and British zones and then into West Germany and East Germany. To add to the disaster, Germany suffered even larger territorial losses than it did in the First World War, with huge portions of eastern Germany directly annexed by the Soviet Union and Poland. The scale of the Germans' defeat was unprecedented. Pan-Germanism became almost taboo because they had been tied so blatantly and self-destructively to racist concepts of the "master race" and Untermenschen by the Nazis. Indeed, racist terms such as "Volksdeutscher" in reference to ethnic Germans in other countries manipulated by the Nazis during World War II later developed into a mild epithet among Hungarians. However, reunification of Germany in 1990 revived the old debates, but this ideology still remains to only the far-right and those who do advocate a "Greater Germany" today are often labeled Fascist and/or neo-Nazi.
