Flags of the German Lands

Federal Republic of Germany (reunified)

Who & why: mass protests through 1989, the fall of the Berlin Wall on 9 November, and the East German Volkskammer's own vote to accede force the issue; formal reunification under the Federal Republic's Basic Law takes effect 3 October 1990, chosen deliberately over any date tied to 1871 or 1933. Germany joins the fully sovereign community of nations for the first time since 1945.

What it represents: the same black-red-gold tricolor the Federal Republic had flown since 1949, now simply extended over the whole reunified country — no redesign, no new symbol, a deliberate statement of unbroken continuity rather than a fresh start.

Federal Republic of Germany (West) / German Democratic Republic (East)

Who & why: the three Western occupation zones consolidate into the Federal Republic of Germany, founded 23 May 1949 in Bonn; the Soviet zone answers five months later, founding the German Democratic Republic on 7 October 1949 in East Berlin. For forty-one years two German states exist side by side — a NATO-aligned parliamentary democracy in the west, a Soviet-aligned one-party state in the east — separated after 1961 by the Berlin Wall itself.

What it represents: both states adopt the same black-red-gold tricolor at first, each claiming to be the sole legitimate Germany. The GDR breaks the symmetry in 1959, adding a state emblem (hammer and compass ringed by a wreath of grain) once reunification looks less likely — from that point the same three colors read as two different countries at a glance.

Allied-occupied Germany

Who & why: unconditional surrender on 8 May 1945 ends the Third Reich; the four victorious Allied powers — the United States, Britain, France, and the Soviet Union — divide the country into occupation zones under the Allied Control Council, with Berlin itself split four ways inside the Soviet zone. No sovereign German government of any kind exists.

What it represents: the Nazi swastika flag is banned outright, and no replacement German national flag is authorized for civilian use anywhere in the country during these four years — ships and public buildings fly the flags of the occupying powers instead. Shown here honestly blank rather than invented.

Nazi Germany (Third Reich)

Who & why: President Hindenburg appoints Adolf Hitler Chancellor on 30 January 1933; the Reichstag Fire Decree and the March 1933 Enabling Act dismantle democratic government within weeks, but 30 January is the standard start point for the regime itself. Hindenburg's 1934 death lets Hitler merge the presidency and chancellorship as Führer. The regime's rearmament, expansion, and the Holocaust culminate in a war that kills tens of millions before unconditional surrender in May 1945.

What it represents: the black-red-gold tricolor is banned; on 12 March 1933 two flags became legal, black-white-red and the Nazi Party flag, and from 15 September 1935 the swastika banner becomes the sole national flag, a totalizing break from every prior German state's symbolism. Shown here in stylized, abstracted form rather than reproducing the emblem itself.

Weimar Republic

Who & why: Kaiser Wilhelm II abdicates on 9 November 1918 as defeat and revolution topple the Empire; the republic is proclaimed the same day, and a National Assembly meeting in Weimar — Berlin still unsettled by street fighting — adopts a democratic constitution in August 1919. Hyperinflation, the Great Depression, and relentless attacks from both the far left and far right leave it chronically unstable until Hitler's appointment ends it in January 1933.

What it represents: the black-red-gold tricolor first raised by liberal revolutionaries and the Frankfurt Parliament in 1848 becomes again an actual national flag, as the Frankfurt Parliament had declared it in 1848–49 — a deliberate assertion of continuity with Germany's own democratic, not monarchical, tradition.

German Empire (Kaiserreich)

Who & why: victory over France in the Franco-Prussian War lets Otto von Bismarck proclaim the German Empire at Versailles on 18 January 1871, with King Wilhelm I of Prussia crowned Kaiser. It is Bismarck's deliberate "small German" solution — Austria permanently excluded — and Prussia dominates the new empire outright: two-thirds of its territory and population, and the Prussian king as hereditary emperor.

What it represents: black-white-red keeps the North German Confederation's flag exactly — Prussia's own black-and-white state colors combined with the red-and-white of the Hanseatic trading cities — now flying over a unified empire rather than a federal union. The throughline from Prussia's own banner to Germany's is now complete and unbroken.

North German Confederation

Who & why: Prussia's decisive victory over Austria at Königgrätz in July 1866 ends the old German Confederation and, crucially, ends any question of Austria leading a unified Germany. The Peace of Prague that August dissolves the Confederation outright; Prussia organizes the German states north of the Main into a new federal union, formalized by a constitution that takes effect 1 July 1867, with the Prussian king as its president and Bismarck as chancellor — a Prussian-led state in almost everything but name.

What it represents: the first appearance of black-white-red as a national flag: Wikipedia says the colours appeared for the first time in 1867 in the constitution of the North German Confederation, and Flags of the World dates the flag to 25 June 1867. Flags of the World gives as the most common theory a combination of Prussia's black-white with the red-white of the Hanseatic League, but says the significance is not completely clear and that it was only a civil ensign in 1867-1870 and became the Empire's merchant flag in 1871.

German Confederation

Who & why: the 1815 Congress of Vienna, filling the void Napoleon left when he dissolved the Holy Roman Empire, creates a loose league of 39 sovereign German states under Austrian presidency, with Prussia as its powerful rival member from the start. The Confederation has a federal diet at Frankfurt but no real central government, no common army, and no common flag of its own — the 1848 Revolution's Frankfurt Parliament briefly tries and fails to build a unified liberal state.

What it represents: black-red-gold is adopted by student fraternities and then the 1848 revolutionaries as the symbol of the liberal-national unity the Confederation itself never delivers — it was the Confederation's colours only briefly: the Bundestag adopted the tricolour on 9 March 1848 and the Frankfurt Parliament declared it the official colours in 1848–49, and FOTW says it was abolished in 1852. Alongside it, Prussia's own black eagle on white: the Hohenzollern kingdom's real state banner, already the strongest single member, already the state that will drive both wars of unification within the next two decades.

Confederation of the Rhine (Napoleonic client states)

Who & why: Napoleon forces the dissolution of the thousand-year-old Holy Roman Empire on 6 August 1806, organizing sixteen (later up to 36) client states — Bavaria and Württemberg elevated to kingdoms, Baden and Hesse to grand duchies — into the Confederation of the Rhine under his own protection. It collapses the moment Napoleon's power does, after the catastrophic 1812 Russian campaign and defeat at Leipzig in 1813; the 1815 Congress of Vienna replaces it with the German Confederation.

What it represents: similar to the Napoleonic-era interruptions elsewhere in this atlas, no single confederal flag existed — each client kingdom kept and flew its own colors under Paris's protection, not a shared German banner. Shown here honestly blank rather than inventing one.

Holy Roman Empire (German lands)

Who & why: Otto I's coronation as Emperor in 962 traditionally marks the start of what later becomes known as the Holy Roman Empire of the German Nation — never a unified state, but a shifting elective realm of hundreds of individual kingdoms, duchies, prince-bishoprics, and free cities, loosely bound to an emperor with real power that waxed and waned across eight and a half centuries, until Napoleon forces Francis II to dissolve it in 1806.

What it represents: the gold field and black eagle was the Emperor's own personal and imperial banner, not a flag of "Germany" as a sovereign state. Wikipedia and Flags of the World both date the double-headed eagle only to about 1401 (the early 15th century); before that the eagle was single-headed (red claws and beak from the late 13th or early 14th century), so the double-headed eagle drawn here fits only the later centuries. The individual German lands within the Empire each kept their own coats of arms and colors. Shown here as the imperial banner only, with that scope made explicit rather than implying a unified German flag that never existed.

Germanic Tribes & the Roman Frontier

Who & why: for roughly nine centuries before Otto I's coronation, "Germany" is not a place with a government but a linguistic and cultural zone of independent tribes east of the Rhine and north of the Danube — first in intermittent contact and conflict with Rome, then gradually consolidating under Frankish rule from the 5th century onward. Charlemagne, a Frank, is crowned Holy Roman Emperor in 800, uniting most of the Germanic-speaking lands (plus Gaul and Italy) under one crown for the first time; the Carolingian Empire's 843 partition among his grandsons leaves East Francia as the direct territorial ancestor of the kingdom Otto I inherits in 936 and crowns into an empire in 962.

What it represents: no flag from this era survives or was likely ever created in any modern sense — shown here honestly blank. Tribes carried standards (the Romans record animal totems and carved wooden or bronze figures on poles) but nothing resembling a woven national flag.

World context: this span runs alongside the building of Rome's Colosseum (70–80 CE) and Pantheon (126 CE), the height and slow decline of the Han dynasty in China, the life of Muhammad and the rapid 7th-century Arab conquests, and Charlemagne's own 800 coronation in Rome — a deliberate echo of the fallen Western Roman Empire three centuries after its last emperor was deposed in 476.
