It was a year that the royal family will look back on fondly, as records were broken and new life was welcomed into the world.
On May 2nd, Princess Charlotte Elizabeth Diana was born inside the Lindo Wing at St. Mary's Hospital in London.
Just 10 hours later, the Duke and Duchess of Cambridge wrapped the little girl in a soft ivory bonnet (a gift from nanny Maria Borrallo's Spanish mother), and took her back to Kensington Palace.
Since her birth, the public has been treated to photos of Charlotte and her big brother, George, from the infant's christening to the family's first Christmas card together.
When the Duke and Duchess pay an official visit to India in the spring, royal fans hope that they'll bring along their two children.
In other royal happenings, Her Majesty surpassed Queen Victoria as the longest-reigning British monarch in history, a milestone that she told others she'd prefer not to make a fuss over.
Check out what else happened over this past year in Windsorville in the slideshow below.
A Princess Is Born
Charlotte Elizabeth Diana of Cambridge made her arrival into the world at 8:34 am local time on May 2nd, weighing 8 lbs., 3 oz. Per tradition, a sign was posted at the gates of Buckingham Palace declaring the news.
Prince George Dabbles In Vintage
When Prince William carried his son, Prince George on to Buckingham Palace's balcony for the 2015 Trooping of the Colour, something about George's outfit looked very familiar. In fact, Kensington Palace confirmed that William wore the exact same thing to the parade in 1984. According to What Kate's Kids Wore, the outfit may be older than that; Charles wore something very similar in a 1950 photo of Cecil Beaton.
One Is Happy And Glorious
At about 5:30 local time on September 9th, 2015, Queen Elizabeth II became the longest-reigning British monarch in history, surpassing her great-great grandmother, Queen Victoria. Her Majesty carried on an engagement that day, treating it as business as usual. "Many, including you First Minister, have also kindly noted another significance attaching to today, although it is not one to which I have ever aspired," the Queen told crowds at Edinburgh Waverley Train Station in Scotland. "Inevitably, a long life can pass by many milestones. My own is no exception. But I thank you all and the many others at home and overseas for your touching messages of great kindness."
Well, This is Awkward
The Sun releaved family footage of the Queen, the Queen Mother, Princess Margaret and Edward VIII in 1933 making a Nazi salute. "Most people will see these pictures in their proper context and time," a palace source told the Daily Mail of the footage. "This is a family playing and momentarily referencing a gesture many would have seen from contemporary news reels. No one at that time had any sense how it would evolve. To imply anything else is misleading and dishonest."
Prince George held his baby sister, Charlotte as the Duchess of Cambridge took the first official photos of the Princess at the family's Norfolk home.
Prince Harry's Remarkable Work
After ending his ten-year career with the army in June, Prince Harry focused his efforts on charitable endeavors. One of them was supporting a 1,000-mile trek through the UK for Walking With The Wounded, an organization that focuses on helping wounded vets recover from their injuries. In this particular shot, Harry embraced a vet who gave him a dog tag belonging to her fallen comrade. It was a touching moment between the two, and signified Harry's dedication to the cause.
