United Kingdom: World War One: One hundred images for one hundred years
On 4 August 2014 it will be 100 years since Europe went to war. To mark the centenary, every day for the hundred days until 4 August we'll be tweeting a picture from our First World War archives from @ICRC_uk.
Follow the countdown to war on Twitter using the hashtag #100pics100years and on Storify: World War One: One hundred images for one hundred years.
The images show the world at war seen through the eyes of our staff and the people the ICRC strived to help.
At the outbreak of World War One, the ICRC was already 50 years old. It was a small institution which was tested to the limits by the sheer scale of the suffering wrought upon civilians and soldiers alike.
The war acted as a catalyst for the ICRC to greatly increase the range and scale of its activities. These included sending its delegates to prison camps to ensure detainees were kept in acceptable conditions, campaigning against the use of chemical weapons, and establishing the International Prisoners of War Agency to find soldiers who had lost contact with their relatives.
