Pan-Germanism ( or ), also occasionally known as Pan-Germanicism, is a pan-nationalist political idea. Pan-Germanists originally sought to unify all the German-speaking people – and possibly also Germanic-speaking peoples – in a single nation-state known as the Greater Germanic Reich (), fully styled the Greater Germanic Reich of the German Nation (). Pan-Germanism was highly influential in German politics in the 19th century during the unification of Germany when the German Empire was proclaimed as a nation-state in 1871 but 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 Austrian-born 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 West and East Germany. Today, Pan-Germanism is mainly limited to some nationalist groups in Germany and Austria. Etymology The word pan is a Greek word element meaning "all, every, whole, all-inclusive". The word "German" in this context derives from Latin "Germani" originally used by Julius Caesar referring to tribes or a single tribe in northeastern Gaul. In the Late Middle Ages, it acquired a loose meaning referring to the speakers of Germanic languages (alongside 'Almain' and 'Teuton') most of whom spoke dialects ancestral to modern German. In English, "Pan-German" was first attested in 1892. In German, there exists a synonym "Alldeutsche Bewegung" which is a calque using German instead of Latin and Greek roots. Origins (before 1860) The origins of Pan-Germanism 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 Years' War with the Peace of Westphalia. Advocates of the Großdeutschland (Greater Germany) solution sought to unite all the German-speaking people in Europe, under the leadership of the German Austrians from the Austrian Empire. Pan-Germanism was widespread among the revolutionaries of 1848, notably
