Flashback: On the Verge of Divorce, Charles and Diana Take William to School

Photos from the young Prince's big day in 1995 — just months before the infamous split.

On September 16, 1995, Prince Charles and Princess Diana did what most parents do come the end of summer: They took their son to school. Then 13 years old, Prince William was accompanied by his mother, father, and 11-year-old brother Harry for his first day at the prestigious Eton College. It was an auspicious occasion for many reasons — and a poignant one in Charles and Diana's troubled marriage. The couple, who married in 1981, had announced their separation in 1992, but only weeks after these photos at Eton, Diana would give a bombshell interview to the BBC in which she'd go into more detail about her and Charles' infidelities. Referring to Camilla Parker Bowles, Diana would also say, infamously, "There were three of us in this marriage, so it was a bit crowded." By December 1995, the Queen herself was urging the two to divorce, a legal split that would eventually become official on August 28, 1996. Here, a look back at one of the last public moments before the final chapter of Charles and Diana's union.

A British TV report from the time noted, "Along with the traditional uniforms and customs, William will face a range of subjects, from cookery to car maintenance, from Latin to Swahili." Prince William follows Eton tradition by signing a book before starting at the school, as Prince Charles, Princess Diana (1961 - 1997) and Prince Harry look on, September 1995.

The happy, optimistic family moment, sadly, would not last.
