Leon Trotsky, a Bolshevik revolutionary, Marxist theorist, and co-leader of the Russian October Revolution, is exiled to Alma Ata, at the time part of the Soviet Union but now located in Kazakhstan. He is later expelled entirely from the Soviet Union to Turkey, accompanied by his wife Natalia Sedova and his son Lev Sedov.

Adolf Hitler is sworn in as Chancellor of Germany in President Paul Von Hindenburg's office, in what observers describe as a brief and simple ceremony. Hitler's first speech as Chancellor takes place on 10 February. The Nazis' seizure of power subsequently becomes known as the Machtergreifung.

During World War I, German zeppelins conduct a bombing raid on Paris. Such raids were rare, because the ships had to fly hundreds of miles over French territory to reach their target, making them vulnerable to attack. Reaching London, conversely, was much easier, because the approach was over German territory and water. The results of these raids were generally not good, but the use of zeppelins as bombers would continue until the end of the war.
