An Old Bolshevik of the Georgian Affair

In 1922, after he called Ordzhonikidze "Stalin's donkey", Ordzhonikidze struck him in the face with his fist. The timing is disputed: one report gives 20 October, while an English-language account places it in November.

Akaki Kabakhidze was a Georgian Old Bolshevik who joined the party in 1904 and belonged to the Society of Old Bolsheviks. Repression records give his birth in 1889 in Ambrolauri, Georgia, nationality Georgian, with residence in Tiflis. In 1922, as a member of the Georgian Communist Party Central Committee, he sided with those opposing Transcaucasian amalgamation, and that year, after calling Sergo Ordzhonikidze "Stalin's donkey", he was struck in the face with the fist. The timing is disputed between October and November accounts. Arrested on 22 December 1936, he was sentenced to death by the Military Collegium of the USSR Supreme Court on 24 June 1937, shot the next day, and rehabilitated on 2 April 1957. Identifying the 1922 figure with the executed man is a source-based inference; a namesake cannot be excluded.

Dictator who built a racist war state

Released from Austrian citizenship in 1925, he remained stateless until he acquired German citizenship in 1932. Appointed chancellor on 30 January 1933, he used the Enabling Act of 23 March 1933 to build a dictatorship and became head of state on 2 August 1934 after Hindenburg's death. His regime was responsible for the genocide of about six million Jews and the deliberate killing of an estimated 19.3 million civilians and POWs. He died by suicide in Berlin on 30 April 1945.

A towering leader of the Indian independence movement, he became independent India's first prime minister in 1947 and held the office until his death in 1964. He anchored the new republic in parliamentary democracy, secularism, and planned economic development, while charting a foreign policy of non-alignment that refused subordination to either Cold War bloc. With Tito he issued the 1954 joint statement that first defined 'non-alignment' as a positive, active policy, not passive neutrality, and went on to co-found the Non-Aligned Movement through the 1956 Brioni Declaration and the 1961 Belgrade summit. The Sino-Indian War of 1962 shook his domestic standing, yet he is remembered as the architect of the Indian republic.

He explained, pointing with an outstretched finger, like a university lecturer — a historian delivering a report on the life and deeds of a long-dead man named Pyatakov, striving to clarify every detail, seized by the single desire that his listeners and students should understand everything correctly."

As JCP Chairman from 1958 to 1982, he steered the party through the Anpo protests and the Sino-Soviet split, but in 1992 the discovery of his 1939 letter denouncing a comrade to the NKVD led to his expulsion from the party he had founded.

In August 1940, redirecting the air offensive toward London and civilian cities gave the RAF time to recover.

Hermann Göring rose from a First World War fighter ace to a central power-holder in Nazi Germany and commander-in-chief of the Luftwaffe.

During the Battle of Britain in 1940, he overestimated the Luftwaffe and was involved in shifting attacks from the RAF's struggling airfields and fighter defences toward British cities, giving Fighter Command time to recover. After the war, the Nuremberg Tribunal condemned him as a major war criminal, and he committed suicide on the eve of his execution.
