If you notice members of the royal family using the hashtag #WeWillRememberThem over the next few days, you should know that it’s for a very good reason.
The campaign is in honor of Remembrance Day, which honors members of the Armed Forces, who have died in the line of duty. (It’s basically the U.S. equivalent to Veterans Day.)
The royal family celebrates the holiday every year, attending engagements and events in the days leading up to Remembrance Sunday. This year, they’re raising awareness with the hashtag #WeWillRememberThem.
