Queen Elizabeth has been the monarch of the United Kingdom and 15 other Commonwealth realms for a record-breaking 65 years. At the age of 94 years old, Her Majesty is not showing any sign of slowing down.

As for her eldest son, Prince Charles, he has been the longest-serving heir to the British throne. While there is no possible way for anyone to say the exact day he’d take the crown, one thing is for sure — he will become King one day.

When Prince Charles becomes King, he will face a tough decision over what he will call himself. There were speculations that the Prince of Wales may follow the footsteps of his grandfather King George VI.

“The last king to be crowned was called Bertie but styled George VI. The one before him went by the name David but was crowned Edward VIII. There is, as yet, no guarantee that Charles will be crowned King Charles III,” royal expert Christopher Wilson said.

Prince Charles may choose King George VII, or King Philip, or King Arthur as his Christian names are Charles Philip Arthur George. However, it is still too early to tell what name he would pick when he becomes King.

Meanwhile, Prince William is the older son of the heir apparent Prince Charles, making him the second in line to the British throne. A previous report claimed that the Duke of Cambridge and his wife, Kate Middleton, will be “burdened” of the reign sooner than expected.

Unlike Queen Elizabeth, Prince Charles will not get that much time. The Prince of Wales is 71 years old as of this writing, and his mother is still the reigning Queen.

But of course, all things must come to an end, even Queen Elizabeth’s reign. But, by the time that Prince Charles becomes King, he will not stay as long on the throne as his mother, who became the Monarch when she was 25. Royal historian Marlene Koenig, then, said that the “burden” is not really on the Prince of Wales but on Prince William and Kate Middleton.

However, it seems that Prince William and Kate Middleton are already prepared for their future roles. The Duke and Duchess of Cambridge have taken over most of the royal engagements during the coronavirus pandemic as Queen Elizabeth and Prince Charles remained in isolation due to their age being considered as high-risk to catch severe COVID-19.
