Recent commentators have asserted Nightingale's Crimean War achievements were exaggerated by media at the time, but critics agree on the importance of her later work in professionalising nursing roles for women. In 1860, Nightingale laid the foundation of professional nursing with the establishment of her nursing school at St Thomas' Hospital in London. It was the first secular nursing school in the world, and is now part of King's College London. In recognition of her pioneering work in nursing, the Nightingale Pledge taken by new nurses, and the Florence Nightingale Medal, the highest international distinction a nurse can achieve, were named in her honour, and the annual International Nurses Day is celebrated around the world on her birthday. Her social reforms included improving healthcare for all sections of British society, advocating better hunger relief in India, helping to abolish prostitution laws that were harsh for women, and expanding the acceptable forms of female participation in the workforce.
