The concept of organised care for the injured was firstly inspired by the Battle of Solferino in 1859. It was here in Northern Italy that the Swiss businessman Henry Dunant witnessed thousands of Italians, French and Austrian soldiers at battle. As he bear witness to the death and destruction, Dunant organised to provide aid to the wounded soldiers which later led to the creation of the International Red Cross.
