Prince William and Kate Middleton have hit a big relationship milestone: a decade of marriage.
The pair tied the knot on April 29, 2011, at Westminster Abbey in London. A million people lined the city streets, hoping to catch a glimpse of the couple, while many more around the world watched the day unfold on TV.

“You could hear it all outside to begin with as she approached,” Martin Fidler said of the royal wedding entrance. “It was like a wave of sound getting louder and louder as she got closer to the Abbey. When the trumpets started inside to announce that she’d arrived, it’s a wonder the roof didn’t lift off!”
A decade later, we look back at Will and Kate’s 20-year relationship history from their college days to parenthood and more.

The college sweethearts met while they were students at the University of St. Andrews in Scotland in 2001. During their second year, they shared a townhouse with two other friends. It wasn't until 2003, though, that the pair reportedly began dating. They were able to keep their relationship hush-hush until they were photographed together on a ski trip in 2004. (Kate is pictured here on their graduation day in June 2005).
