Princess Diana brought her signature determination to her campaigning against landmines.

She was already known for her other charitable endeavors, such as her role in the 1987 opening of the U.K.’s first HIV/AIDS unit in London, which was designed specifically to treat patients with the virus at a time when it was perceived with much stigma. Pool/Samir Hussein-WireImage Why Princess Diana walked across a minefieldĪt the time of Princess Diana’s visit to Angola in January 1997, Prince William and Prince Harry were 14 and 12 years old, and her divorce from Prince Charles had been finalized the previous year. Since then, 164 countries have become parties to the agreement, which is informally known as the Ottawa Treaty. Her untimely death in August 1997 came only a few months before the United Nations Mine Ban Treaty - a legally binding prohibition on the use, stockpiling, production and transfer of landmines - was opened for signature. The photographs of Princess Diana wearing protective clothing and equipment, as well as her meeting landmine survivors, raised the profile of the work being done to clear landmines around the world. Harry is honoring Princess Diana’s advocacy against landmines in Angola by making a trip very similar to the one his mother made in January of 1997, when she walked across a minefield in Huambo in central Angola. The tour across southern Africa begun Monday by Prince Harry, Duke of Sussex Meghan, Duchess of Sussex and their son, Archie Mountbatten-Windsor, will surely be as modern as they are - but Prince Harry’s plan for Thursday and Friday has also echoed the past.
