Second World War
Why were Atomic Bombs Dropped on Hiroshima and Nagasaki?
The bombing of Hiroshima and Nagasaki in August 1945 brought an end to the Second World War, but at a terrible cost to the Japanese civilian population, and signalling the dawn of the nuclear age. What had led to the fateful decision to deploy these new weapons of mass destruction?

How Winston Churchill And The Conservative Party Lost The 1945 Election
The 1945 election was the first general election to be held in Britain since November 1935. Churchill had proved himself to be a popular leader during the Second World War, so he was confident that the Conservatives would win this election based on his wartime success.

The End Of The British Empire After The Second World War
After the Second World War, the disintegration of Britain's empire transformed global politics. Before the war, Britain maintained colonies all over the world, which provided valuable raw materials, manpower and strategic bases. By 1945, however, colonies were an expensive liability for Clement Attlee's newly elected Labour government. 
On the right two benches of the accused leaders stretch away from the foreground to the centre of the painting. Behind the defendants stands a line of white-helmeted military police who guard the benches and separate them from the court beyond. On the left, in front of the defendants, sit two rows of lawyers, largely in black robes. The lawyers and the defendants study sheaves of paper.

A Short History Of The War Crimes Trials After The Second World War
After the end of the Second World War, the Allies brought the leading civilian and military representatives of wartime Germany and Japan to trial on charges of war crimes, crimes against peace and crimes against humanity. The principles of the trial of the Nazi leadership were agreed at a meeting of the ‘Big Four’ – Britain, the United States, the Soviet Union and France – in London in the summer of 1945, resulting in the Nuremberg Charter.

Reimagining Victory

In 1945, the Allied nations marked the end of the Second World War on VE Day and VJ Day. 

But in today’s context, as conflicts descend into protracted crises, what does it really mean to ‘win’ a war and what challenges do we face when it comes to peacebuilding? Journalists, peacebuilders, artists and academics question the concept of victory through a series of debates, discussions and performances.
