1645 On September 28th, a grand theatre in London sang the song "God Save the King" for the first time. This song is popular, easy to sing, solemn and majestic, and deeply loved by the people. By 1825, it has become the national anthem of Britain. Now the national anthems of other countries in the world come from this place. This national anthem, named "God Bless the King", has been changed to "God Bless the Queen" since the Victorian Dynasty if a woman inherits the throne.

Now more than 20 countries in the world take this song as their national anthem or quasi-national anthem. Liechtenstein completely adopted the melody of the British national anthem, and Switzerland also used it for a long time. It was not until 196 1 that another national anthem was chosen. Commonwealth countries such as New Zealand, Canada and Australia, although they also have their own national anthems, all take the British national anthem as the official national anthem.
