Parliament repealed the tax the following year, but the episode became an early flashpoint in the growing dispute over taxation without representation that led toward the American Revolution.

Britain, France, and Russia signed the London Protocol, recognising an autonomous Greek state under their joint protection.

The agreement built on earlier great-power intervention in the Greek War of Independence against Ottoman rule, following the allied naval victory at Navarino. It set out preliminary borders and status for the future Greek kingdom, though full independence and final boundaries were not settled until further negotiations the following year. Britain's role in Greek independence reflected its broader strategic interest in the Eastern Mediterranean and containing Ottoman and Russian power.

Nazi Germany opens the Dachau concentration camp, its first, near Munich.

Established by Heinrich Himmler just weeks after Hitler became chancellor, Dachau initially held Communists, Social Democrats, and other political opponents of the Nazi regime before expanding to imprison Jews, Roma, clergy, and other targeted groups. It became a model for the broader Nazi concentration camp system and remained in operation until its liberation by American forces in April 1945, by which point tens of thousands of prisoners had died there.

The Royal Navy fought off a stronger Italian battle fleet in the Second Battle of Sirte, protecting a vital convoy bound for besieged Malta.

A British force of light cruisers and destroyers, heavily outgunned by Italian battleships and cruisers, used smoke screens and aggressive destroyer attacks to shield the merchant convoy through a fierce Mediterranean storm. Although the convoy was later damaged by air attack near Malta, the Royal Navy's tactical success in fending off the Italian fleet helped sustain the besieged island through one of the most critical periods of its wartime blockade.

The attack, launched in the final weeks of the war, dropped a mix of high-explosive and incendiary bombs that ignited firestorms across Hildesheim's medieval centre, killing over 1,000 people and destroying numerous half-timbered buildings and churches dating back centuries. The devastation was among the most severe suffered by any German town of its size and remains a contested episode in debates over the necessity of late-war Allied bombing.

The United Kingdom formally granted independence to Transjordan, ending its League of Nations mandate over the territory.

The Treaty of London ended direct British control while Britain retained military basing rights and continued to subsidise and train the Transjordanian army. Emir Abdullah I, who had ruled under British oversight since the 1920s, took the title of king, and the state was later renamed the Hashemite Kingdom of Jordan in 1949 after it annexed the West Bank.
