They picked Louis Arthur Charles, and he will be known as Prince Louis.

Kate Middleton, Duchess of Cambridge, gave birth to Prince William's first child on July 22, 2013. Officially called George Alexander Louis, Prince George became a big brother on May 2, 2015. The boy is third in line to succeed his great-grandmother, after his grandfather Charles and his father.

These happy chubby cheeks belong to none other than Queen Elizabeth II. She is in the arms of her mother Elizabeth, the Duchess of York. Her father was the future King George VI. Elizabeth II's birth was a difficult one: The heiress to the throne was finally delivered via C-section on April 21, 1926. She grew up with her younger sister Margaret (1930-2002). Today, she is 92 years old.

This young boy was born on June 10, 1921. At the time, Philip, Duke of Edinburgh didn't realize that about 25 years later he would be asking the hand of a future queen in marriage: Elizabeth II.

The failure of their marriage would be just as publicized. Diana's death in a car accident on the night of August 31, 1997 would be followed by another media frenzy. Her fans still mourn her today.

Prince William Arthur Philip Louis Mountbatten-Windsor was born on June 21, 1982 in London. After their parents separated in 1992, William and his brother Harry lived alternately with Princess Diana in London's Kensington Palace or with their father and grandmother Elizabeth II at the Royal Court.

His real name is Prince Henry Charles Albert David Mountbatten-Windsor. But the world prefers to simply call him Prince Harry. The sandy-haired baby was born on September 15, 1984. Harry's excessive partying as a teenager would later make tabloid headlines. He managed to get rid of his bad-boy image, and later married Meghan Markle. They now have children of their own.
