The memorial service of Queen Elizabeth II, on Friday evening, witnessed the change of the words of the national anthem from "God save the Queen" to "God save the King", for the first time in 70 years.

The memorial service at St. Paul's Cathedral in the British capital, London, which began minutes after the new King Charles III delivered the first address to the nation, was attended by Prime Minister Liz Terrace, in addition to a number of clergy and dignitaries.

For the first time in 70 years, the church choir performed the national anthem using the phrase "God Save the King," which was last sung in 1952, before changing to "God Save the Queen" with Elizabeth II's accession to the throne.

It is noteworthy that this is the national anthem of the United Kingdom and New Zealand, as well as in countries that recognize the British monarch as head of the Commonwealth, such as Australia, Canada and others.

Queen Elizabeth II passed away at Balmoral Castle at the age of 96, on Thursday, after seventy years in power, making her the longest-reigning British monarch on the throne.

The Queen ascended the throne in 1952 and her era witnessed tremendous social changes.
