Why does the Estonian national anthem have the same melody as the Finnish national anthem?

Forget it if you don’t believe it, I support the poster. The two national anthems have the same melody, but they are just the national flag song, that is, the national flag song, and the flag song. There are a few countries or regions in the world that are like this (Taiwan, Estonia, Finland) It is very interesting to sing the national anthem before raising the flag (playing the national flag song) in the flag-raising ceremony. It is different from most countries~hehehe

The following is a positive answer: Estonia’s national anthem "My Land, My Joy" "The lyrics of the song are written by Johann Voldemar Jannsen (Johann Voldemar Jannsen), and the music was composed by Fredrik Pacius. Pacius is also the composer of the Finnish national anthem "Our Country" Composer. Now you understand, the composer of the national anthems of both countries is the same person!

The following is the Estonian government's official interpretation of the national anthem in English:

The Estonian national anthem "My Native Land..." is a choral-like melody arranged by a Finnish composer of German origin Fredrik Pacius in 1843. In Estonia, Johann Voldemar Jannsen's lyrics were set to this melody and sung at the first Estonian Song Festival in 1869.

It is also mentioned that the Estonian national anthem is based on the lyrics of the Finnish national anthem< /p>
