National AIDS Trust
One of the most important causes for Diana was the fight against HIV/AIDS. Not only did she serve as patron of the trust, which promotes the awareness of AIDS and helps prevent the spread of HIV, but she took her sons to meet with those who had contracted the virus. As a result, it has also become one of the most important causes for Harry. During his gap year, Harry worked in the tiny African kingdom of Lesotho — the country had one of the highest rates of HIV/AIDS in the world — and 10 years ago he set up the charity Sentebale to raise funds and awareness.
