King of Prussia who signed the Declaration of Pillnitz and campaigned against France

In August 1791 he co-signed the Declaration of Pillnitz with Leopold II in support of the French king, and in 1792 he joined in person the campaign led by the Duke of Brunswick.

He succeeded his uncle Frederick II as King of Prussia in 1786 and, at home, turned away from his predecessor’s enlightened style towards tighter censorship and religious control. In reaction to the French Revolution he set aside the old rivalry with Austria: in August 1791 he joined Leopold II in the Declaration of Pillnitz, and a formal alliance followed in February 1792. He took part in person in the 1792 and 1793 campaigns against France, but was held back by lack of money while his advisers looked more to the partitions of Poland. He signed a separate peace with France at Basel in 1795 and died in 1797.

Holy Roman Emperor who co-signed the Declaration of Pillnitz

On 27 August 1791 he and the King of Prussia signed the Declaration of Pillnitz, saying they would act together for the French king if the other powers joined them.

A son of Maria Theresa and brother of Marie Antoinette, he ruled Tuscany as a reforming grand duke from 1765 and abolished the death penalty and torture there in 1786. He succeeded his brother Joseph II as emperor in 1790. In August 1791 at Pillnitz he and Frederick William II declared that they would intervene in France only if the other powers joined them. Historians have called it a formality, since Leopold knew Russia and Britain would not act, but it contributed to the radicalisation of the revolutionary movement in France. He died of pneumonia in Vienna on 1 March 1792, shortly before France declared war.

French king deposed and tried during the Revolution

The National Convention ruled on 3 December 1792 that it would try Louis XVI itself; convicted of high treason by vote, he was guillotined on 21 January 1793.

King of France from 1774, Louis XVI summoned the Estates-General in 1789 amid a fiscal crisis. He accepted the Constitution of 1791, but the Flight to Varennes and foreign war deepened distrust of the crown. The monarchy was suspended in 1792; the National Convention convicted him and he was executed in January 1793.

Monarchs and royalty French monarchy 1757–1836 ○ Died in exile

Count of Artois who led émigré royalism during the Revolution

At his 1825 coronation at Reims he tried to revive the royal touch, asserting the sacredness of monarchy; in July 1830 his ordinances dissolved the chamber and censored the press, and the Paris rising forced his abdication on 2 August.

Louis XVI’s younger brother, the Count of Artois left France soon after the fall of the Bastille in 1789. Abroad he promoted Bourbon restoration and became a political centre of émigré royalism. He succeeded as Charles X in 1824 and was overthrown by the July Revolution of 1830.

Government and administration Consulate and First Empire state institutions 1769–1821

A conqueror who rose from revolutionary general to emperor

In the coup of 9–10 November 1799 (18 Brumaire), he conspired with Talleyrand and Sieyès and used troops with fixed bayonets to disperse the Council of Five Hundred and overturn the Directory, then took effective power as First Consul.

Born into an Italian-descended Corsican family, he was commissioned in the French royal artillery in 1785, supported the Revolution of 1789, and rose through his victories over royalists at Toulon in 1793 and Vendémiaire in 1795. The Italian campaign of 1796 made him a national hero, and in November 1799 the Brumaire coup overthrew the Directory and made him First Consul; in 1804 he became emperor of the First Empire. He won at Austerlitz in 1805 but was ruined by the Russian campaign of 1812 and Leipzig in 1813, was exiled to Elba in 1814, and after the Hundred Days lost at Waterloo and died on Saint Helena in 1821. His reforms such as the Napoleonic Code and public education endure, while the plunder of occupied lands, suppression of the press and deportation or imprisonment of critics, and the restoration of slavery in the colonies make him a contested figure.

Monarchs and royalty Russian Empire 1818–1881 ✕ Assassinated

The Tsar who tried to modernize the old regime from above through emancipation and reform, and became the revolutionaries' prime target

To the Moscow nobility in 1856: "The existing order of serf-owning cannot remain unchanged. It is better to begin abolishing serfdom from above than to wait until it begins to abolish itself from below."

Taking the throne in 1855 amid the defeat of the Crimean War, Alexander II declared it better to abolish serfdom 'from above than to wait until it begins to abolish itself from below,' and in 1861 he emancipated 23 million serfs, following up with zemstvo self-government, judicial reform, and universal military conscription. Hailed as the 'Tsar-Liberator,' he found his reforms too little for the radicals and too much for the conservatives, and after an assassination attempt in 1866 he turned toward reaction. On 13 March 1881, the very day he approved the Loris-Melikov constitutional draft, a bomb thrown by a member of the People's Will mortally wounded him; he died in the Winter Palace. His death ended the era of Great Reforms, ushered in the reaction of Alexander III, and confirmed revolutionary terrorism as a decisive method in Russian politics.

Monarchs and royalty Russian Empire 1845–1894 ○ Nephritis

The 'Peacemaker' who reversed the Great Reforms and re-established autocracy as the unshakeable creed of the Russian state

When the Austrian ambassador threatened war, Alexander III twisted a silver fork into a knot, threw it onto the ambassador's plate, and said: 'That is what I am going to do to your two or three army corps.'

Alexander III ascended the throne in 1881 over the body of his assassinated father, Alexander II, and drew a single lesson: reform breeds revolution. He immediately issued Pobedonostsev's Manifesto on Unshakeable Autocracy, killing the constitutional proposals his father had approved, and launched systematic counter-reforms: weakening the zemstvos, placing peasant communes under noble Land Captains, and enshrining 'Orthodoxy, Autocracy, Nationality' as state creed alongside aggressive Russification and the anti-Jewish May Laws of 1882. In foreign affairs he avoided major wars and earned the epithet 'The Peacemaker.' Yet his signature achievement, the Franco-Russian Alliance of 1892, created the framework that would draw Russia into World War I. The autocratic order he rebuilt and handed to Nicholas II was precisely what the revolutions of 1905 and 1917 would shatter.

Monarchs and royalty Russian Empire 1868–1918 ✕ Executed

The last Tsar, who believed autocracy was a duty from God

On the night of 2 March 1917, after signing the act of abdication, Nicholas II wrote in his diary: "At one in the morning I left Pskov with a heavy feeling of what I had lived through. All around there is treason, cowardice, and deceit!"

After the shootings of 1905, and even after taking personal command in 1915 and with it the blame for defeat, he held autocracy to be a trust from God that could not be yielded by an inch. In February 1917, when no army would fire for him, three hundred years of Romanov rule ended in a week; in July 1918 he was shot with his family in a cellar in Yekaterinburg.

Religion Affiliation unconfirmed 1869–1924 ○ Natural death

The Tibetan-born reincarnate lama enthroned as the last great khan of Mongolia

'The princes feared him, the common people loved him.'

Born in Lhasa, Tibet, the 8th Jebtsundamba Khutuktu was, after the Dalai and Panchen Lamas, the highest living incarnation in Mongolian Buddhism. When the Qing dynasty collapsed in 1911, Mongol nobles enthroned him on 29 December as the 'Bogd Khan' ('Holy Ruler') of a new theocratic state. Stripped of power when China abolished autonomy in 1919, he was reinstated as a limited monarch after the 1921 revolution and died of throat cancer on 20 May 1924, ending the monarchy. The first and last great khan of Outer Mongolia since the late 17th century, he held Mongols together amid upheaval through his religious charisma.

Monarchs and royalty Italy state institutions 1869–1947 → Died

A monarch caught between constitutional authority and responsibility for Fascism

On 25 July 1943, he dismissed Mussolini, had him arrested, and appointed Badoglio to head a new government.

As king of Italy, he presided over the decline of liberal constitutionalism, the consolidation of the Fascist state, and two world wars. He approved Mussolini's seizure of power, colonial wars, the racial laws, and entry into the Second World War, making the monarchy a participant in Fascist rule. In July 1943 he dismissed Mussolini and appointed Pietro Badoglio, using the crown's constitutional powers to open a legal route for governmental change, but his flight from Rome after the armistice left the armed forces and state in disarray. He abdicated in 1946 after the monarchy failed to recover its legitimacy.

The last Empress, whose reliance on Rasputin helped doom the dynasty

When told of Nicholas's abdication, Alexandra said only: 'Dieu donne que cela sauve la Russie!' — 'God grant that this may save Russia!'

Granddaughter of Queen Victoria, Alexandra became Empress of Russia in 1894 and guided Nicholas II with an unshakeable conviction that autocratic power was a divine trust that could not be compromised. Desperate to save her hemophiliac son Alexei, she fell under the sway of Grigori Rasputin, and during World War I (with Nicholas at the front as supreme commander) she dismissed and replaced ministers on Rasputin's counsel, effectively directing domestic policy. Her German birth, her reliance on Rasputin, and her refusal of political reform earned her public hatred and accelerated the collapse of the Romanov dynasty. On 17 July 1918 she was shot by Bolsheviks in the cellar of the Ipatiev House in Yekaterinburg, alongside her husband and five children.

Monarchs and royalty Ethiopia 1892–1975 ✕ Murdered by the Derg after deposition

Moderniser and anti-fascist icon who never touched the land order that finally undid his dynasty

In 1936 he told the League of Nations, 'God and history will remember your judgment.'

Descended from the Solomonic dynasty, Haile Selassie I was the 20th-century emperor who modernised Ethiopia and, with his 1936 speech to the League of Nations, became a global symbol of anti-fascism. From his regency he drove reform through the 1931 constitution and the abolition of slavery, and after exile under Italian occupation he returned with British forces in 1941 to restore the throne. But his modernisation, which left the northern rist and gult tenures and the southern land-grant system intact through compromise with the nobility and clergy, never freed the peasantry from tenancy, and the 1972 Wollo famine turned opinion against him. Deposed by the Derg in September 1974, he was strangled on the junta's orders the following August, months after the proclamation that nationalised the land system his reign had preserved.

Monarchs and royalty Yugoslavia 1893–1976 → Died

A regent pressed toward the Axis while trying to keep Yugoslavia out of war

Two days after Yugoslavia joined the Tripartite Pact on 25 March 1941, a military coup removed him from the regency.

Paul Karađorđević was the prince regent who governed the Kingdom of Yugoslavia for the minor Peter II after the assassination of Alexander I. He sought to soften the legacy of centralised rule and reconcile the state with the Croatian national movement, culminating in the 1939 Cvetković-Maček Agreement and the creation of the Banovina of Croatia. As war spread and British and French guarantees weakened, his attempt to preserve neutrality shifted toward concessions under German pressure, and Yugoslavia’s 1941 accession to the Tripartite Pact triggered a military coup that removed him. He lived in exile after the war, died in 1976, and was rehabilitated by a Serbian court in 2011.

Monarchs and royalty Japan state institutions 1901–1989 ○ Natural causes

The emperor who carried Japan through war and constitutional transformation

“Enduring the unendurable”, a phrase from his 1945 rescript announcing Japan’s surrender

Hirohito was Japan’s 124th emperor from 1926 to 1989, occupying both the sovereign position of the imperial constitution and the symbolic role defined by the postwar constitution. He stood at the apex of the state that authorized Japan’s aggression and Pacific War, while the extent of his responsibility for the war and its crimes remains contested. After Hiroshima, Nagasaki, and the Soviet entry into the war left the Supreme Council deadlocked, he intervened to accept the Potsdam terms and announced the surrender by radio. After the war he renounced imperial divinity and remained a symbolic head of state, while continuing his research in marine biology.

Monarchs and royalty Qing dynasty 1906–1967 ↓ Abdicated 1912 · natural causes

Last emperor of the Qing, puppet emperor of Manchukuo, and a “remoulded” citizen of the People’s Republic

Crowned China's last emperor before he was seven, he lost the throne to the 1911 revolution and was restored once in 1917. Through Manchukuo's chief executive and emperor to Soviet captivity in 1945, he was amnestied in 1959 and shown as a model of reeducation.

Enthroned at three as the Xuantong Emperor, he abdicated in the 1911 revolution. Expelled from the Forbidden City in 1924, he went to the Japanese concession in Tianjin and in 1932 became chief executive, then emperor, of Japan’s puppet state Manchukuo. Captured by the Soviets in 1945 and returned to China in 1950, he was “remoulded” at the Fushun war criminals’ prison and pardoned in 1959. He lived as a gardener and later a political-consultative delegate in Beijing and died of illness in 1967, early in the Cultural Revolution.

Monarchs and royalty Vietnam 1913–1997 → Died in exile

Last emperor of the Nguyễn dynasty, who abdicated in 1945 and returned as head of the French-backed State of Vietnam

Bảo Đại abdicated in August 1945, returned as head of the State of Vietnam in 1949, and was ousted in a 1955 referendum organized by Ngô Đình Diệm’s government.

The thirteenth and last emperor of the Nguyễn dynasty, he came to the throne in 1926 as nominal ruler of the French protectorates of Annam and Tonkin. When Japan overthrew the French in March 1945 he became emperor of the Japanese-sponsored Empire of Vietnam; after the August Revolution he abdicated in Huế on the 30th and became “supreme advisor” to Ho Chi Minh’s government. Soon in exile, he returned under the Élysée Accords of 1949 as Chief of State of the French-backed State of Vietnam, criticised as too close to France and too often abroad. Ousted by Ngô Đình Diệm in a 1955 referendum, he died in Paris in 1997.

Monarchs and royalty Romania 1921–2017 ↓ Forced to abdicate; died in exile

The last King of Romania, who arrested Antonescu on 23 August 1944 to bring the country over to the Allies and abdicated at gunpoint in 1947

On the morning of 30 December 1947, in a palace surrounded by troops, Groza and Gheorghiu-Dej put the abdication before him. Michael testified in exile that he was told refusal would mean bloodshed and the shooting of a thousand students held in custody. That afternoon parliament proclaimed the People's Republic.

Born to Crown Prince Carol of the House of Hohenzollern-Sigmaringen and Helen of Greece, he became king at six in 1927 under a regency because his father had renounced the succession, and was demoted to crown prince when Carol II returned to take the throne in 1930. When Antonescu deposed Carol II in September 1940 he was crowned again at eighteen, but power lay with Antonescu's dictatorship and the Axis alliance. On 23 August 1944, with the Red Army across the border, he arrested Antonescu in a palace coup, concluded an armistice with the Allies and turned Romania against Germany, becoming one of the very few foreigners awarded the Soviet Order of Victory. Yet in March 1945 he had to appoint the Groza government under Vyshinsky's pressure, and his "royal strike" of refusing to sign decrees from August that year could not stop the rigged election of 1946 or the Maniu trial of 1947. On 30 December 1947 he signed the abdication forced on him by Groza and Gheorghiu-Dej, and the People's Republic was proclaimed the same day. Stripped of citizenship in 1948, he lived in Britain and Switzerland as a test pilot and a broker; a million people gathered in Bucharest on his first return at Easter 1992. His citizenship was restored in 1997, and he died in Switzerland in 2017, buried with a state funeral in the royal necropolis at Curtea de Argeș.

Cambodian king and united-front leader

In June 1982 he joined the Khmer Rouge and Son Sann's KPNLF in an anti-Vietnamese coalition government and became its president, retaining Cambodia's UN seat.

King, head of state and prime minister of Cambodia. He came to the throne in 1941 under French colonial rule, led the country to independence in 1953, abdicated in 1955 to enter politics and was removed in 1970. Held under house arrest under the Khmer Rouge in 1975–1979, he led a resistance coalition allied with the Khmer Rouge in 1982–1991, was restored as king in 1993 and abdicated again in 2004.

Monarchs and royalty Yugoslavia 1923–1970 ○ Died

The last king who carried Yugoslavia’s royal legitimacy into exile

On 27 March 1941, Dušan Simović told him: "Your Majesty, from this moment you will exercise your full sovereign power."

Peter II became king of the Kingdom of Yugoslavia as a child after the assassination of his father, Alexander I, and was its last monarch. The 27 March 1941 coup ended the regency and declared him of age, but the Axis invasion soon forced him to lead a government in exile from London. His crown represented state continuity against occupation, yet the exile government’s divisions and the Partisans’ military and political victory stripped it of an effective base of power. After the monarchy was abolished in 1945, his permanent exile left unresolved the question of Yugoslavia’s political legitimacy.
