Radical French prime minister at the end of the First World War who pressed harsh terms on Hungary at the Paris Peace Conference
A physician turned journalist from the Vendée, he became mayor of the 18th arrondissement of Paris in 1870 and the next year tried to broker a compromise between the Paris Commune and the government. A key figure of the Independent Radicals, he advocated the separation of church and state. As interior minister in 1906 he ordered repressive policies toward the workers’ movement and was nicknamed “the Tiger”, and he was prime minister in 1906–1909 and 1917–1920. Appointed in November 1917 at one of the darkest hours of the war, he demanded total victory over Germany and achieved the Treaty of Versailles at the Paris Peace Conference. Seeking to weaken Hungary as Germany was weakened, he brought about the stringent terms of the Treaty of Trianon. He died in 1929.
Aristocratic statesman who led Hungary’s delegation to the Paris peace talks in 1920 and pleaded for revising Trianon at the League
A count born in Vienna, he entered parliament in 1877 and was a leading orator for half a century. As education minister in 1906–1910 he drafted the Apponyi laws of 1907, which imposed Hungarian-language teaching on non-Hungarian schools. He led the Hungarian delegation at the Paris peace talks in January 1920 and spoke on 16 January, without changing the terms, and in March lost the regency vote to Horthy. Thereafter, as a legitimist opposition deputy and Hungary’s representative at the League of Nations, he denounced the injustice of the Trianon borders. He died in Geneva in 1933, where he had come for the Disarmament Conference.
US president whose Fourteen Points and League of Nations failed to win the Senate’s ratification
Born in Virginia, he was president of Princeton University and governor of New Jersey before winning the presidency in 1912, and in his first year imposed racial segregation across the federal bureaucracy. In April 1917 he asked Congress to declare war over unrestricted submarine warfare, and in January 1918 set out the Fourteen Points, with a League of Nations and self-determination. At the Paris Peace Conference he presided over the drafting of the League Covenant but conceded much to the other powers to get it. A stroke in October 1919 incapacitated him, and his refusal of a compromise sank the Senate’s ratification of the treaty. The Palmer Raids of the Red Scare came in the same years. He received the 1919 Nobel Peace Prize and died in 1924.

Conservative viceroy of India and foreign secretary who gave his name to the Curzon Line and led the Allies at Lausanne
Born into an aristocratic Derbyshire family and educated at Eton and Oxford, he entered Parliament in 1885 and wrote travel books warning of a Russian threat to India. As Viceroy of India from 1899 to 1905 he pursued administrative reform, but his 1905 partition of Bengal was criticised as an attempt to divide Bengali nationalism, and a major famine coincided with his tenure. In the First World War he served in Lloyd George’s war cabinet; appointed Foreign Secretary in October 1919, he gave his name to the proposed Soviet-Polish boundary, the Curzon Line. He designed the Treaty of Sèvres and, as chief Allied negotiator at Lausanne in 1922, settled the borders of Turkey. Passed over for prime minister in 1923, he died in 1925.
Italian prime minister who led the country to victory after Caporetto but failed to win its territorial claims at the peace conference
Born in Palermo, he became a renowned law professor and from 1897 sat in the Chamber of Deputies as a Liberal. When the government fell after the defeat at Caporetto in October 1917 he became prime minister, dismissed Cadorna and rebuilt the army, and the victory of Vittorio Veneto in 1918 earned him the name “Premier of Victory”. At the peace conference he demanded Dalmatia, promised by the Treaty of London, and Fiume, obtained neither, walked out in April 1919 and resigned in June. The “mutilated victory” helped Mussolini’s rise. He at first supported Mussolini but broke with him after the murder of Matteotti in 1924. He died in Rome in 1952.

A statesman caught between diplomacy and responsibility under military pressure
In June 1945 he approached Malik, while the Soviet side prolonged the talks to gain time for its war preparations against Japan.
Kōki Hirota was a Japanese imperial diplomat and politician who proclaimed international cooperation yet failed to restrain the military’s policy of expansion in China and beyond. As foreign minister and prime minister, he helped restore the active-duty military-minister system and advanced the Anti-Comintern Pact, choices that narrowed civilian autonomy. In June 1945 he approached Soviet ambassador Yakov Malik to explore mediation for ending the war, but the Soviet government used the contacts to delay while preparing its entry into the war against Japan. Convicted of war crimes at the Tokyo Trial, he was hanged in 1948 as the only civilian executed there, a responsibility and sentence that remain contested.
