Discover all about the birth of Prince Louis, including his name, significance, and place in royal succession. Learn about the royal family’s traditions and the historic importance of this new arrival in the British monarchy. From the birth details to royal wedding plans, get the latest updates on the young prince’s entry into royal life.

On April 23, 2018, the Duchess of Cambridge, Kate Middleton, welcomed her third child with Prince William at London’s Lindo Wing of St. Mary’s Hospital. The royal family announced the birth shortly after, and the couple introduced their new son, Prince Louis, to the world a few hours later.
The baby’s name, Louis Arthur Charles Cambridge, was revealed after four days of speculation. He holds the official title, His Royal Highness Prince Louis of the United Kingdom, and is fifth in line to the throne, following Prince Charles, Prince William, Prince George, and Princess Charlotte.
Born at the same hospital wing as his siblings, Prince George and Princess Charlotte, Prince Louis weighed 8 lbs 7 oz — the heaviest newborn in a century for the family. His birth was celebrated with traditional gun salutes fired by the British Army in London.
This naming and birth have significant historical importance. The Succession to the Crown Act 2013 ensures gender neutrality in the line of succession, solidifying Princess Charlotte’s position despite her gender. Kate Middleton plans to attend Meghan Markle and Prince Harry’s royal wedding on May 19, 2018, shortly after her son’s arrival.
Overall, Prince Louis’s birth marks a noteworthy milestone in royal history, symbolizing continuity and change within the monarchy.
