t’s a prince! On Monday, the world welcomed the newest addition to the royal family and the future heir to England’s throne.

Palace officials confirmed the arrival of His Royal Highness the Prince of Cambridge, born at St. Mary’s Hospital at 4:24 PM BST, weighing 8 lbs 6 oz.

The birth marks a new era for not only the first-time parents but also the extended royal family. As third in line to succeed the throne after his grandfather Prince Charles and his father, Prince William, he’s the first baby born under new succession laws.

The modernized bill amends a centuries-old policy, allowing the royal couple’s first-born child the right to inherit the throne regardless of gender.
