Queen Elizabeth Ⅱ, the previous monarch of the United Kingdom (U.K.), passed away on September 8th at the age of 96. Her funeral was held at London’s Westminster Abbey, and several billion mourners participated worldwide. As the Queen passed away, Prince Charles was declared the new monarch of the U.K. on September 10th, bringing up some political concerns. Queen Elizabeth Ⅱ was famous for keeping her political neutrality following the adage, “Never complain, never explain.” However, Charles has actively clarified his opinions on issues such as climate change and environmental problems over the years, drawing concerns about his political neutrality. In addition, as movements toward republicanism grow in some areas of the Commonwealth, his enthronement has become one of the significant issues in reconstructing diplomatic relations with the association. Thus, the relationship between the U.K. and the 56 countries that form the Commonwealth could collapse in her absence. Furthermore, voices have long been raised toward abolishing the monarchy in Australia and some Caribbean nations, including Jamaica. Richard Fitzwilliams, a royal historian in the U.K., said, “One of the major challenges for King Charles Ⅲ would be to make the monarchy appealing for the younger generations.” Meanwhile, the King’s coronation will be held at Westminster Abbey next spring.
