Photography: 98 for 98 The century in photographs: today 1939

A woman window-shopping in London with her Kenyan cheetah reflected colonial trade and prosperity, but as the public prepared for the different lifestyle that world war would bring, this image swiftly became representative of a bygone era. By March, Hitler had entered Prague, less than six months after saying that he had no more territorial claims in Europe. Hooting and hissing welcomed the Nazis in Prague, and this echoed in the debating- rooms of world leaders, not least because it was the first time that Hitler had occupied territory not inhabited by people of German origin. Chamberlain denounced Hitler and recalled the British ambassador from Berlin, showing the pointlessness of rhetoric and written agreements.

The moves to defend vulnerable countries, such as the Anglo-French-Polish military alliance, were less about diplomacy than a scramble to join whatever countries looked the best prepared for war. By May, Mussolini signed the "Pact of Steel" with Germany to support each other in the war, and in August, Germany and the Soviet Union signed a non-aggression pact. The outbreak of a European war appeared virtually inevitable.

Whilst Hitler rallied support, the European powers concentrated on preparations for war. Even before the developments in Prague, the RAF had stepped up plane production to more than 400 aircraft a month, competing with Germany's 600. The Territorial Army was doubled; production of weapons, factories, camps and uniforms was stepped up. The most potent disruption was in the patterns of everyday life: more than 2 million children were evacuated, football games were cancelled as players were called up for service, and the Mediterranean and the Baltic were closed to British merchant shipping.

On 3 September, the British prime minister declared that "This country is now at war with Germany. We are ready." The expected blitz did not happen straightaway. and for a while the petty officialdom, regulations and posters exhorting people not to travel and not to spread rumours were like baubles in a shop window: merely an indication of things to come.
