The 25 Biggest Royal Family Moments of the Past Decade

The decade started out with a bang! Prince William and Kate Middleton finally announced their engagement in late 2010 after nine years of dating. The pair met in university and commoners were buzzing about who William would choose to be his future wife — and the future queen of the Commonwealth! He proposed during a trip to Kenya and Kate said it was very romantic.

Introducing the Duke and Duchess of Cambridge! Their wedding was such an important day for the Royal Family that it was deemed a national holiday for Brits. Their special day spared no expense, coming in at a wild cost of $34 million, with two billion people watching the live broadcast from around the world. Kate's long sleeved gown was elegantly stunning and William looked like he couldn't be happier in the many photos taken that day.

The milestones for Will and Kate were coming in hot at the start of the decade. Their pregnancy announcement was not only exciting because it was their first child, but also because the future baby would be knocking Prince Harry out of third in line for the throne (after Prince Charles and William).

On this day, Will and Kate announced the birth of a baby boy at St. Mary's Hospital in London. The future king was named George Alexander Louis, but would be formally known as Prince George of Cambridge.

This passion project was started by Prince Harry in 2014. The games celebrate the abilities of service men and women around the world who endured life-changing injuries while in duty. They compete in a series of sports, with the first event kicking off in Harry's hometown of London.

The first-time parents decided to add another baby to the mix. The palace announced Kate was pregnant with her second child a little over a year after Prince George was born. While it's unlikely this baby will ever reign in the commonwealth, they would technically be fourth in line to take the title.

The Duke and Duchess of Cornwall celebrated 10 years of marriage on this day. They tied the knot at St. George's Chapel in Windsor, with Camilla wearing a striking gold headpiece that's worth remembering.

It's a girl! Will and Kate named their little one Charlotte Elizabeth Diana, a touching tribute to her great grandmother, Queen Elizabeth, and her late grandmother, Princess Diana. This bundle of joy is known as Princess Charlotte of Cambridge and was also born at St. Mary's Hospital like her brother. The palace shared an adorable photo of her and big brother, George to celebrate the occasion.

Happy birthday, your majesty! The reigning Queen celebrated a major milestone by turning 90 in 2016. Fun fact: the Queen actually has two birthdays. The day she was born, on April 21, as well as a summer date in June called Trooping the Colour, a 260-year-old tradition celebrating the official birthday of the sovereign.

The longest reigning monarch celebrated a significant milestone in 2016. Queen Elizabeth was only 25-years-old when she ascended the throne following her father's passing. She's ruled longer than any other monarch in British history, and continues to perform royal duties at 93 years of age.

It's always a special time when the royals pursue a group project. The trio started the Heads Together campaign which aims to end the stigma about mental health and encourage people to seek help if they need it. This topic is near and dear to Will and Harry, who both opened up about the struggles they faced after the tragic loss of their mother, Princess Diana, in 1997. The video is a raw and real conversation between the royals, something that doesn't happen very often for the public to see.

After 70 years, the palace announced Prince Phillip is retiring from royal duties. Formally known as the Duke of Edinburgh, Phillip has been a full-fledged royal since marrying Queen Elizabeth in 1947. It's been quite the ride, and the Duke finally decided to take it easy at 96 years old.

The third time's the charm. There was a ton of speculation about whether or not Kate was expecting, and the palace officially announced it in late 2017. This baby would soon become the fifth heir to the throne and a royal cutie in no time.

They grow up so fast! The palace shared these adorable photos of 4-year-old Prince George attending his first day of school at Thomas's Battersea in London.

Cue the start of a whirlwind romance. After this day, Prince Harry would no longer be known as one of the world's most eligible bachelors. Enter Meghan Markle, an American actress best known for her role on the hit show Suits. Harry and Meghan flaunted their love for the public to see for the first time in Toronto during the Invictus Games. To say the world went into a frenzy is an understatement, and this would be the start of the young couple's every move being watched from that point on.

Congratulations were in order for Queen Elizabeth and Prince Phillip in 2017. The two celebrated a whopping 70 years of marriage! That is certainly no easy feat, especially while being in the public eye.

Harry and Meghan's love story is a fairytale come to life. On this day, Meghan officially said goodbye to life as she knew it and said hello to joining the British royal family. She made history becoming the first American to marry into the modern royal family.

Hello, baby number three! On this day, Louis Arthur Charles was born at St. Mary's Hospital, weighing in at 8 pounds, 7 ounces. He would formally be known as Prince Louis of Cambridge and officially turn Will and Kate's circle into a family of five.

On this historic day, Meghan and Harry would officially become the Duke and Duchess of Sussex. Hearts melted as Meghan officially became a member of the family and fulfilled every little girl's dream of becoming a princess. The couple shared their wedding day not only with their 600 guests, but also 1,200 lucky members of the public who were invited to the shindig. The estimated cost of their wedding greatly trumped Will and Kate's, ringing in at $45 million. It was a beautiful day full of gorgeous dresses and decor, and it is completely worthy of being turned into a Disney movie.

All eyes were on Meghan and Harry for the first time since their royal wedding. The newlyweds officially attended their first royal duty about a month after having a romantic honeymoon.

Meghan and Harry weren't the only ones having a royal wedding in 2018. His cousin, Princess Eugenie, had a beautiful ceremony with her fiance, Jack Brooksbank. Her dress was stunning, and she proudly chose to display her scar from a scoliosis surgery from when she was 12 years old.

Less than one year after the pair got married, Meghan and Harry proudly announced they would be expecting their first child! This baby would officially be seventh in line to the throne and the eighth

great-grandchild for Queen Elizabeth and Prince Phillip. The news is also exciting for George, Charlotte, and Louis because they would officially be expecting their first cousin.

The longest reigning monarch officially made history when she published her first Instagram post. While the royal family has had an Instagram account for years, this was the first time Queen Elizabeth actually shared something herself. The public has the Science Museum to thank for this momentous day, since she had chosen to share a personal story from one of their archives.

The world eagerly waited for the announcement of Meghan and Harry's baby news. The couple chose to steer away from the tradition of facing the public the day of giving birth, which is totally respectable. After a few days, they made their first public appearance as a family and formally introduced Archie Harrison Mountbatten-Windsor.

Princess Charlotte officially became a pupil when she joined her brother George at Thomas's Battersea for her first day of school. This time, Kate was able to join sending off her kid to school for the first day, which is lucky for us because the photos are adorable.
