As part of a long-standing royal tradition, 2025 will mark a significant change for Prince George as he begins preparations for his future role as King.

In just seven months, the 11-year-old will experience a major shift—one that will separate him from his parents and siblings due to an established royal rule designed to protect the line of succession.

For those needing a refresher, Prince George, the eldest child of Prince William and Kate Middleton, will celebrate his 12th birthday on July 22, 2025. While he is not expected to ascend the throne anytime soon, like future monarchs before him, much of his life will be dedicated to preparing for the role.

Currently second in line to the throne, George follows his father, Prince William, 42, and grandfather, King Charles III, 76. However, history has shown that succession can be unpredictable. Queen Elizabeth II became monarch at just 25 after her father, King George VI, passed away suddenly. His own reign was unplanned, as he had to step in following the unexpected abdication of his brother, Edward VIII.

Because the timing of a monarch’s ascension is uncertain, official preparations for Prince George are crucial. A key part of these preparations will begin in July 2025, when George will no longer be permitted to travel with his parents or siblings.

Since Prince William is first in line to the throne, royal protocol dictates that direct heirs should not travel together in case of a tragic accident, such as a plane crash. This measure ensures that at least one successor remains safe to maintain the stability of the monarchy.

Prince William followed the same rule, traveling with his family—including his parents and brother—until he turned 12. After that, he was required to travel separately.
