Why was Mary seacole not allowed to go to the Crimean war with Florence Nightingale?

Mary Seacole was not allowed to accompany Florence Nightingale to the Crimean War due to racial prejudice and discrimination. Despite her qualifications and experience as a nurse and healer, her Jamaican heritage led to her being overlooked for official recognition and support by the British military. Nightingale's team was predominantly composed of white nurses, and Seacole had to independently fund her journey to the war, ultimately setting up her own hospital to care for soldiers.
